6. Platform Summary

6.1

The Platform is a marketplace where Buyers and Sellers can find each other, and advertise, buy and sell products and/or services online. Piazza Smart operates the marketplace and may provide promotional opportunities for Sellers (together, the "Piazza Smart Services"); Sharetribe provides the underlying technology infrastructure (including hosting and maintenance), and payments from Buyers to Sellers at checkout are processed securely by Stripe. Collectively, these are referred to as the "Services". We facilitate the Piazza Smart Services in accordance with these Terms and all applicable laws. You understand and agree that we only make available the Piazza Smart Services. We are not party to any agreement entered into between a Buyer and a Seller and we have no control over the conduct of Sellers, Buyers or any other users of the Platform. Interactions between Buyers and Sellers are at the buyers' and sellers' own risk, subject to statutory consumer rights under UK law.

Providers are the sole sellers of record. Piazza Smart is a technology platform only. Piazza Smart does not:

• (a) verify Seller identity, credentials, product claims, or online selling experience;
• (b) control pricing, fulfilment, inventory, or how a Seller sells; or
• (c) act as agent, partner, or joint venturer with any Provider.

We exclude all liability for Provider actions, false information, or misrepresentations to the maximum extent permitted by UK law.

6.2

A Seller wanting to provide products and/or services creates an Account on the Platform and posts an accurate and complete description of the products and/or services they can provide, including the fees for the products and/or services, including delivery, and customs and duties ("Listing Fees") ("Seller Listing").

6.3

Unless otherwise agreed with us in writing, a Seller's Listing Fees may be no higher than they charge on any other website or platform for the same products and/or services.

6.4

We may place limits on the number of Seller Listings that a Seller may post at any given time.

6.5

A Buyer wanting to buy products and/or services may create an Account on the Platform to view and browse Seller Listings, or browse as a guest.

6.6

A Buyer may request to purchase the goods and/or services described in a Seller Listing by sending a request through the Platform. The request is an offer from the Buyer to the Seller to book/buy the goods and/or services described in the Seller Listing ("Purchase Request"). As a Buyer, you acknowledge and agree that we will share your contact details and personal information (email address, phone number, physical billing address, physical shipping address, full name if you're not an organization) with the relevant Seller(s) when you make a Purchase Request. Our third-party payment provider(s) will collect and store your payment details as you enter them to the Platform.

6.7

A Seller will be obliged to automatically accept the Purchase Request through the Platform, and it will become a "Confirmed Purchase". If the Seller cannot fulfil the Purchase Request, it will be obliged to refund the relevant Buyer. As a Seller, you acknowledge and agree that we will share your contact details and personal information (email address, full name if you're not an organization) with the relevant Buyer when you receive a Purchase Request.

6.8

The Seller confirms that it is legally entitled to and capable of supplying the products and/or services described in the Purchase Request.

6.9

Buyers and Sellers may enter into written agreements in relation to the goods and/or services. To the extent there is inconsistency between any additional terms and conditions and these Terms, these Terms will prevail.

6.10

Sellers must include all additional terms and conditions relating to their products and/or services in the relevant Seller Listing. By sending a Purchase Request, a Buyer is accepting the additional terms and conditions of the relevant Seller.

All Provider Terms of Sale must include: 14-day right to cancel, clear returns policy. The 14-day post-fulfilment limit applies to "no questions asked" cancellations under UK Consumer Contracts Regulations 2013; disputes/chargebacks via Stripe have a longer window (up to 120 days), but Providers should respond within 7 days to protect account standing.

6.11

We are not responsible or obliged to verify the identities of Buyers or Sellers on the Platform, nor are we obliged to verify the goods or services being offered on the Platform or any Seller Listings (including in relation to their compliance with laws). We may review a Seller Listing before it is posted to the Platform, but we are not obliged to, and we may also remove Seller Listings from the Platform at any time, at our sole discretion, including where the content of a Seller Listing is abusive, vague, or makes unverified claims such as "vintage" or "antique". Liability for vague descriptions or unverified claims in listings rests with Providers.

---

7. Promotional Opportunities

As a Seller, you may choose to purchase promotional opportunities, such as a feature in our email marketing or social media or placement on our home page (Promotional Opportunity). Promotional Opportunities are subject to the fees and the terms and conditions as set out in any Promotional Opportunity offer and displayed on the Platform or otherwise communicated to you. In the event of any conflict between any Promotional Opportunity terms and conditions and these Terms, the Promotional Opportunity terms and conditions will prevail.

---

8. Promotions and Gift Vouchers

8.1 Promotional codes:

We may from time to time issue promotional discount codes for use on the Platform to Buyers. These discounts will apply to our Service Fees only, and will not affect the amount of the Listing Fees owed to the Seller. Where you are issued with a promotion discount code, you must enter the promotion discount code at the time of making a purchase through the Platform, to claim the discount. Only one promotion code can be used per purchase and it may not be used in conjunction with any other discounts or promotional codes or offers. Promotion codes do not have a monetary value and cannot be sold or redeemed for cash and are non-transferable. Unredeemed promotion codes will only be valid for the validity period made known to you at the time of providing the promotion code and cannot be used after the date of expiration. It is your responsibility to keep track of the expiration date. Failure to use the promotion code according to these Terms, including but not limited to, publication or selling of the promotion code or obtaining the promotion code through an unauthorised channel, is prohibited and may constitute fraud. A promotion code will not be accepted if the code is invalid or does not match the code on our system. If we become aware, or have reason to suspect, that you are fraudulently obtaining or misusing promotion codes and/or have breached these Terms, we may cancel all purchases made by you using the promotion code. Our decision is final in all matters relating to a promotion code offer. Further conditions of use relating to promotional discount codes may be set out on our website or made available to you at the time of providing you with the promotional discount code.

8.2 Gift Vouchers:

We may, from time to time, offer gift vouchers for purchase on our Platform. Gift vouchers do not have an expiry date. If you are purchasing a gift voucher for another person, you should ensure that they are aware of these Terms. If the amount of your gift voucher does not cover the total Listing Fees for the products and/or services you wish to purchase, you will need to pay the remainder of the purchase with another payment method, or with another gift card. Gift vouchers are not redeemable for cash and cannot be returned for a cash refund or exchanged. This clause does not seek to limit any rights you may have under any applicable English consumer laws, including the Consumer Rights Act 2015. Gift vouchers cannot be used to purchase gift vouchers. Any unused balance will remain as credit on a gift voucher and is not transferable for a cash payment.

Your use of the gift voucher may be declined where there is fraud, deception or reasonable suspicion of illegal activities in connection with your use.

8.3 Discounts:

We may from time to time apply discounts on items offered by Sellers on the Platform. These discounts will apply to our Service Fees only, and will not affect the amount of the Listing Fees owed to the Seller.

---

9. Communication

9.1

We may contact you via the Platform using in-Account notifications, or via off-Platform communication channels, such as text message or email.

9.2

Buyers and Sellers must only share their contact details to organise the provision of the products and/or services once a Purchase Request has been made.

9.3

Sellers must not advertise their contact details publicly on their Account profile on the Platform, unless expressly authorized in writing by Piazza Smart to do so.

9.4

Buyers or Sellers must not otherwise seek to transact outside the Platform, or otherwise attempt to circumvent the payment of Service Fees to us.

---

10. Payments

10.1

As a Buyer, you agree to pay (and your chosen payment method will be charged with) the Listing Fees at the time you make a Purchase Request.

10.2

In consideration for operating the Platform, we will charge the services fees to the Seller as set out on the Platform ("Service Fee"), plus any third-party payment processing fees. You acknowledge and agree that we have no control over, and we will not be responsible or liable for, any fees set by our payment provider(s). The Service Fee and the payment processing fees will be deducted from the Listing Fees, and will be paid to us and the payment provider at the same time as the Buyer pays the Listing Fees through the Platform. To the maximum extent permitted by law, the Service Fee and the payment processing fees are not refundable, including in circumstances where a Seller chooses to provide a Buyer with a refund.

Payments are processed by Stripe, and card data never touches our servers. We do not promise instant payouts—timing depends on Provider verification, order fulfilment, and Stripe's settlement schedule.

10.3

The Listing Fees minus the Service Fee and the payment processing fees will be deposited in a Seller's merchant account as linked in their Account after payment by the Buyer.

10.4

Where a Seller wishes to purchase a Promotional Opportunity, the Seller agrees to pay (and your chosen payment method will be charged with) the fee set out on the Platform (or as otherwise agreed between the Parties) for the Promotional Opportunity at the time of purchase ("Promotional Opportunity Fees").

10.5

The payment methods we offer for the Listing Fees and Promotional Opportunity Fees are set out on the Platform. We may offer payment through a third-party provider. You acknowledge and agree that we have no control over the actions of the third-party provider, and your use of the third-party payment method may be subject to additional terms and conditions.

10.6

You must not pay, or attempt to pay, the Listing Fees or Promotional Opportunity Fees by fraudulent or unlawful means. If you make a payment by debit card or credit card, you warrant that you are authorised to use the debit card or credit card to make the payment. If payment is made by direct debit, by providing your bank account details and accepting these Terms, you authorise our nominated third-party payment processor to debit your account in accordance with these Terms and you certify that you are either an account holder or an authorised signatory on the account for which you provide details.

10.7

You agree that we may set off or deduct from any monies payable to you under these Terms, any amounts which are payable by you to us in connection with the Platform.

10.8

We do not store any credit card details, and all payment information is collected and stored through our third-party payment processor.

---

11. Refunds and Cancellation Policy

11.1

The cancellation, exchange, variation, repair, return or refund of any products and/or services ordered on this Platform are strictly a matter between the relevant Buyer and Seller, as are all other aspects of the purchase and delivery process. The terms and conditions agreed to between the Seller and the Buyer must be set out clearly in the relevant Seller Listing. All Sellers agree to ensure they comply with the Consumer Rights Act 2015 and any other applicable laws in the refund of any Listing Fees. Nothing in this clause is intended to limit your rights as a consumer under UK applicable law.

We facilitate dispute resolution but are not liable for Provider actions. Piazza Smart facilitates transactions between independent makers and buyers. We are not the seller of record. Claims regarding item quality, delivery, or description must be resolved directly with the Provider, with our dispute workflow. We encourage Buyers and Sellers to resolve disputes in good faith before escalating.

11.2

This clause will survive the termination or expiry of these Terms.

---

12. Reviews

12.1

Buyers of products may review their experience with the Seller on the Platform, including the product ("Review").

12.2

Reviews can be viewed by any user and will remain viewable until the relevant Account is removed or terminated. You acknowledge and agree that the first part of your email address may be publicly displayed next to your Review.

12.3

You agree to provide true, fair and accurate information in your Review. If we consider that the Review is untrue, unfair, inaccurate, offensive or inappropriate, we may delete the Review or ban you from posting the Review. We do not undertake to review each Review. To the maximum extent permitted by law, we are not responsible for the content of any Reviews.

12.4

You can write a Review about a Seller if you have had an experience with that Seller, which means that (1) you have engaged the Seller through the Platform; or (2) you can otherwise document your interaction with the Seller in relation to the Platform, including via correspondence (collectively referred to as a "Buyer Experience").

12.5

You may not write a Review about a Seller you have previously owned, currently own, or which an immediate family member currently owns, or if you are an executive or employee of that Seller, or work for the Seller. Similarly, you may not write a Review about a direct competitor to the Seller that you own, are employed by or work for.

12.6

Your Buyer Experience must have occurred in the 12 months prior to you writing a Review.

12.7

You may only write about your own Buyer Experience. You are not permitted to write a Review about somebody else's Buyer Experience, such as that of a family member or friend.

12.8

You are encouraged to be specific and factual in your Reviews. If you have been offered an incentive by a Seller to write a Review, you should include information about this in your Review. Incentives include the Seller offering you a gift, reward, discount or advantage for writing a Review about the Seller on the Platform.

12.9

This clause will survive the termination or expiry of these Terms.

13.1

• (a) you do not assert that you are the owner of Our Intellectual Property;

14.3

You agree that you are solely responsible for all User Content that you make available on or through the Platform, including on social media using a Tag or in any of our groups or channels on social media platforms. You represent and warrant that:

• (a) you are either the sole and exclusive owner of all User Content or you have all rights, licences, consents and releases that are necessary to grant to us the rights in such User Content (as contemplated by these Terms);
• (b) neither the User Content nor the posting, uploading, publication, submission or transmission of the User Content or our use of the User Content on, through or by means of our Platform (including on social media) will infringe, misappropriate or violate a third party's intellectual property rights, or rights of publicity or privacy, or result in the violation of any applicable law or regulation; and
• (c) all User Content will be in English.

14.4

We do not endorse or approve, and are not responsible for, any User Content. We may, at any time (at our sole discretion), edit, remove or hide any User Content (including if it contains abusive or offensive material).

However, we will not be liable for damage which you could have avoided by following our advice to apply an update offered to you free of charge, or for damage which was caused by you failing to correctly follow installation instructions or to have in place the minimum system requirements advised by us.

16.5

While we strive to always make the Platform available to you, we do not guarantee that it will be available 100% of the time. The Platform is hosted and maintained by Sharetribe, our technology partner; disruptions may occur due to scheduled maintenance, emergency updates, third-party infrastructure issues, or circumstances beyond our reasonable control. We will use reasonable endeavours to minimise downtime and notify you of planned maintenance where practicable, but we are not liable for any loss arising from temporary unavailability of the Platform, except where such liability cannot be excluded under UK law.

16.6

To the maximum extent permitted by law, we will not be liable for, and you waive and release us from and against, any Liability caused or contributed to by, arising from or connected with:

• (a) any third-party services;
• (b) any unavailability of the Platform;
• (c) any aspect of the Buyer and Seller interaction, including without limitation the products and/or services offered by the Seller, the description of the products and/or services requested or offered, any advice provided, the performance of services or supply and delivery of products by the Seller; or

16.7

Subject to clauses 16.1 (no limitation in respect of deliberate default), clause 16.4 (damage caused by defective digital content) and 16.3 (liability which cannot legally be limited), but despite anything to the contrary, to the maximum extent permitted by law, where you use this Platform as an individual consumer (and not as a business):

• (1) we only operate the Platform for domestic and private use. If you use the Platform for any commercial, business or re-sale purpose we will have no liability to you for any loss of profit, loss of business, business interruption, or loss of business opportunity; and
• (2) if we fail to comply with these Terms, we will not be responsible for any losses that you suffer as a result, except for those losses which are a foreseeable consequence of our failure to comply with these Terms.

16.8

Subject to clauses 16.1 (no limitation in respect of deliberate default), 16.4 (damage caused by defective digital content) and 16.3 (liability which cannot legally be limited), but despite anything to the contrary, to the maximum extent permitted by law, to the extent you use the Platform as a Seller, or a business (including where you are a Buyer):

  • (a) any Liability we incur due to your breach of these Terms,
  • (b) any claim (including from any tax authority) for any VAT for which you are responsible that you did not correctly declare or remit to the relevant tax authority,
  • (c) any Liability we incur due to you providing us with false or misleading information, and
  • (d) any Liability we incur as a result of your interaction with a Buyer or a Seller, including as a result of any transaction between you and a Buyer/Seller;
• (2) neither Party will be liable for any Consequential Loss; and
• (3) our aggregate liability for any Liability arising from or in connection with these Terms will be limited, in our sole discretion, to us resupplying the Piazza Smart Services to you or to us repaying you the amount of the Service Fees paid by you to us in respect of the supply of the relevant Piazza Smart Services to which the Liability relates.

Provider agrees to indemnify Piazza Smart for claims arising from: (a) inaccurate descriptions; (b) illegal goods; (c) breach of UK law; (d) customer disputes. By listing on Piazza Smart, you warrant your items comply with UK law and are accurately described.

You agree to indemnify and hold harmless Piazza Smart Ltd, its directors, and agents from any claims, losses, or costs (including legal fees) arising from your listings, transactions, or breach of this Agreement. This obligation survives termination of your Account.

16.9

We have given commitments as to the compliance of the operation of the Platform with these Terms and applicable Laws. In view of these commitments, the terms implied by sections 3, 4 and 5 of the Supply of Goods and Services Act 1982 are, to the maximum extent permitted by law, excluded from these Terms.

This clause will survive the termination or expiry of these Terms.

18. Sustainability Guidelines

18.1

We encourage Sellers to work towards providing sustainable goods and services. Our Sustainability Guidelines published below are non-mandatory and voluntary, and are provided for self-certification. Providers can advertise on the Piazza Smart website that they comply with one or more Guidelines, or with other ethical criteria, under their own responsibility and liability. Piazza Smart makes no representations about the environmental, ethical, or sustainability attributes of any Provider's products or services.

18.2

You acknowledge and agree that any certification under the Sustainability Guidelines is self-certified by the Seller, and we are not responsible, nor do we endorse or verify, any certifications or claims that a Seller applies to their business on the Platform, including any certifications that a Seller has self-assessed against the Sustainability Guidelines. Where you are a Buyer, you agree to conduct your own due diligence on the Seller before making a purchase from the Seller.

---

19. Seller insurance

As a Seller, we may request that you provide evidence of your insurance. Where we do so, we are not confirming that the insurance you have is sufficient or suitable for the products and/or services you choose to provide to Buyers. If we do not ask you to provide evidence of insurance this does not indicate that we believe you do not require insurance. You acknowledge and agree it is your responsibility to make your own investigations and receive professional advice on the insurance you require.

---

20. General

20.1 Assignment:

You must not assign or deal with the whole or any part of your rights or obligations under these Terms without our prior written consent. We may assign or deal with the whole or any part of our rights or obligations under these Terms without your prior written consent.

20.2 Assignment of Debt:

You agree that we may assign or transfer any debt owed by you to us, arising under or in connection with these Terms, to a debt collector, debt collection agency, or other third party.

20.3 Confidentiality:

Other than where the disclosure cannot lawfully be excluded, each Party agrees not to disclose any confidential information it may access on or through the Platform to a third party, or otherwise misuse such confidential information. Confidential information may include confidential information supplied to you by us, by a Buyer, or by a Seller. This clause will survive the expiry or termination of these Terms.

20.4 Contracts (Rights of Third Parties) Act 1999:

Notwithstanding any other provision of these Terms, nothing in these Terms confers or is intended to confer any right to enforce any provision of these Terms on any person who is not a party to them.

20.5 Disputes:

Dispute resolution is a process where an independent body considers the facts of a dispute and seeks to resolve it, without you having to go to court. Where you are a Buyer and you are not happy with how we have handled any complaint, you may want to contact the alternative dispute resolution provider we use. You can submit a complaint to The Law Society of the United Kingdom via their website at https://www.lawsociety.org.uk/en. The Law Society of the United Kingdom will not charge you for making a complaint and if you are not satisfied with the outcome you can still bring legal proceedings. Where you are a Seller, if we and you cannot agree how to resolve a Dispute between us, a Party may not commence court proceedings relating to a dispute without first meeting with the other Party to seek (in good faith) to resolve the dispute, failing which the Parties agree to engage a mediator to attempt to resolve the dispute. The costs of the mediation will be shared equally between the Parties. Nothing in this clause will operate to prevent a Party from seeking urgent injunctive or equitable relief from a court of appropriate jurisdiction.

20.6 Entire Terms:

Subject to your Consumer Law Rights, these Terms contain the entire understanding between the Parties and the Parties agree that no representation or statement has been made to, or relied upon by, either of the Parties, except as expressly stipulated in these Terms, and these Terms supersede all previous discussions, communications, negotiations, understandings, representations, warranties, commitments and agreements, in respect of their subject matter.

20.7 Force Majeure:

Neither Party will be liable for any delay or failure to perform their respective obligations under these Terms if such delay or failure is caused or contributed to by a Force Majeure Event, provided the Party seeking to rely on the benefit of this clause, as soon as reasonably practical, notifies the other Party in writing about the Force Majeure Event and the extent to which it is unable to perform its obligations, and uses reasonable endeavours to minimise the duration and adverse consequences of the Force Majeure Event.

20.8 Further assurance:

Each Party must promptly do all things and execute all further instruments necessary to give full force and effect to these Terms and their obligations under the same.

20.9 Governing law:

These Terms are governed by the laws of England and Wales. Each Party irrevocably and unconditionally submits to the exclusive jurisdiction of the courts operating in England and Wales and any courts entitled to hear appeals from those courts and waives any right to object to proceedings being brought in those courts.

20.10 Notices:

Notice of legal proceedings sent by you to us shall be exclusively served by registered post at our geographical address stated at the start of these Terms, and will be deemed to have been served three business days after the date of mailing (seven business days if airmail or international mailing is involved). For the purpose of legal notices to us, business days are days in which the banks are open for business in both the place of mailing and the UK. Any notice given by us to you under these Terms will be at your email or physical address (by registered post in case of the physical address) provided in your Account or otherwise on the Platform. Any notice to you will be deemed to have been served three business days after the date of mailing (seven business days if airmail or international mailing is involved) in the case of post, or after 24 hours in the case of transmission by email (unless we receive notification that the email address is invalid). If the 24 hour term falls on a day which is not a business day in the place of receipt, or it expires after normal business hours in the place of receipt, then the notice shall be deemed to have been received by you on the next day which is a business day in the place of receipt. For the purpose of legal notices to you, business days are days in which the banks are open for business in both the UK and the place of receipt.

20.11 Prevailing Language:

You agree that the English text of these Terms (and of any documents that form an integral part of the same, including the Sustainability Guidelines and the Restricted Items Policy) is the authoritative legal version and shall prevail over all versions in other languages in the event of a dispute. We are under no obligation to provide you with a translation of these Terms into any given language.

20.12 Privacy:

We will handle your personal data in accordance with our Privacy Policy, available on our website.

20.13 Relationship of Parties:

These Terms are not intended to create a partnership, joint venture, employment or agency relationship between the Parties.

20.14 Severance:

If a provision of these Terms is held to be void, invalid, illegal or unenforceable, that provision is to be read down as narrowly as necessary to allow it to be valid or enforceable, failing which, that provision (or that part of that provision) will be severed from these Terms without affecting the validity or enforceability of the remainder of that provision or the other provisions in these Terms.

20.15 Third-party sites:

The Platform may contain links to websites operated by third parties. Unless we tell you otherwise, we do not control, endorse or approve, and are not responsible for, the content on those websites. We recommend that you make your own investigations with respect to the suitability of those websites. If you purchase goods or services from a third-party website linked from the Platform, such third party provides the goods and services to you, not us. We may receive a benefit (which may include a referral fee or a commission) should you visit certain third-party websites via a link on the Platform ("Affiliate Link") or for featuring certain products or services on the Platform. We will make it clear by notice to you which (if any) products or services we receive a benefit for to feature on the Platform, or which (if any) third-party links are Affiliate Links.

20.16 Waiver:

Any failure or delay by a Party in exercising a power or right (either wholly or partially) in relation to these Terms does not operate as a waiver or prevent that Party from exercising that power or right or any other power or right. A waiver must be in writing and will be effective only to the extent specifically stated.

Sustainability Guidelines for Piazza Smart Sellers

The Piazza Smart Certificate

Effective from: 10 March 2026

Welcome to this special space, where you will be introduced to Piazza Smart's unique sustainability concept and vision for the future of shopping. In this page, we outline how third-party sellers can self-certify the sustainability of items on our website using the exclusive Piazza Smart Certificate.

A Self-Certification Scheme

Sellers can self-certify that their products and services meet at least one of our 15 Sustainability Guidelines below by displaying the Piazza Smart Certificate on their listings.

The Piazza Smart Certificate is a self-certification scheme which operates on the basis of trust, and it is up to the seller to ensure they are providing truthful and accurate information when certifying themselves.

Sellers are responsible for guaranteeing that the Piazza Smart Certificate accurately reflects their business practices.

If you have reason to believe that a Piazza Smart Certificate displayed in relation to a product or service is false or misleading, you are encouraged to voice your concerns by writing to us at info@piazzasmart.com and we will look into the issue.

The 5 Piazza Smart Certificate Labels

This is the emblem of the Piazza Smart Certificate. It comes in five colours, signifying five increasing levels of sustainability – much like a leaf turning from autumn orange to spring green, or a gemstone growing from beautiful to exceptionally precious. All products embedding eco-conscious practices are indeed valuable gemstones mounted in the frame of a stronger economy.

Topaz Orange

If the item you offer on Piazza Smart as a seller meets at least one of the 15 Guidelines, you will be entitled to display the first-level, Topaz Orange Piazza Smart Certificate on your listing.

Zircon Yellow

If the item you offer on Piazza Smart as a seller meets at least 3 of the 15 Guidelines (or 20% of the Guidelines that are relevant to your particular business, more on this later), you will be entitled to display the second-level, Zircon Yellow Piazza Smart Certificate on your listing.

Sapphire Green

If the item you offer on Piazza Smart as a seller meets at least 6 of the 15 Guidelines (or 40% of the Guidelines that are relevant to your particular business, more on this later), you will be entitled to display the third-level, Sapphire Green Piazza Smart Certificate on your listing.

Emerald Green

If the item you offer on Piazza Smart as a seller meets at least 9 of the 15 Guidelines (or 60% of the Guidelines that are relevant to your particular business, more on this later), you will be entitled to display the fourth-level, Emerald Green Piazza Smart Certificate on your listing.

Diamond Green

If the item you offer on Piazza Smart as a seller meets at least 12 of the 15 Guidelines (or 80% of the Guidelines that are relevant to your particular business, more on this later), you will be entitled to display the fifth-level, Diamond Green Piazza Smart Certificate on your listing.

As a seller, you may only use the Certificate to label your relevant listings on our website. If you want to make additional uses of it, you must first ask for our prior written permission by writing at info@piazzasmart.com. The Certificate must be displayed by someone with the power to make representations on behalf of you and your company or other entity (if any).

We are a startup, and we may not have implemented yet a dedicated function on the website for you to display the Certificate on your listings. In this case, you can make use of existing functions or, if you encounter difficulties, wait until we implement the appropriate functionality. You can also reach out to info@piazzasmart.com for assistance.

How to Use the Guidelines

Our 15 Sustainability Guidelines are listed and explained below. As a seller, you can just pick one of them, verify that your product or service complies with it, and display the Topaz Orange Piazza Smart Certificate on your listing, specifying which Guideline the Certificate refers to. You may also choose to comply with 50% of one Guideline and 50% of another (more on this in our section on flexibility below).

If your item fully complies with multiple Guidelines, you might be able to upgrade your Certificate all the way up to the Diamond Green level, as described below. You must always specify which Guidelines the Certificate refers to. You are entitled to upgrade your Piazza Smart Certificate based on how many Guidelines your items fulfil that are relevant to your particular business.

For example, if you are a fashion seller selling an item including plant-based and animal-based materials, all 15 Sustainability Guidelines will be applicable to your listing. This means, if your jacket on the Piazza Smart marketplace only meets Sustainability Guideline number 2, it will be entitled to our first-level, Topaz Orange Certificate. Should it meet, however, Sustainability Guidelines number 2, 5, and 9, it will be entitled to our second-level, Zircon Yellow Certificate, because it complies with at least 20% of the Guidelines relevant to your industry. And should it meet Sustainability Guidelines number 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 15, it will be entitled to our top-level, Diamond Green Certificate, because it complies with at least 80% of the Guidelines relevant to your industry.

If your jacket on the Piazza Smart marketplace doesn't use plant-based nor animal-based materials, only 13 Sustainability Guidelines will be applicable to your listing (excluding Guidelines no. 13 and 14). This means, if your jacket only meets Sustainability Guideline number 2, it will be entitled to our first-level, Topaz Orange Certificate. Should it meet, however, 2.6 Sustainability Guidelines (for example number 2, 5, and 60% of number 9), it will be entitled to our second-level, Zircon Yellow Certificate, because it complies with at least 20% of the Guidelines relevant to your industry. And should it meet 10.4 Sustainability Guidelines (for example number 2, 3, 5, 6, 7, 8, 9, 10, 12, and 15, and 40% of Guideline no. 11), it will be entitled to our top-level, Diamond Green Certificate, because it complies with at least 80% of the Guidelines relevant to your industry.

If, on the other hand, you are a service provider working only with a computer and without your own office (a home office or a client's office doesn't count as an office), the Guidelines relevant to you will be number 1, 2, 4, 5, 6, 8, 10 and 15. In this case, your services will be entitled to the top-level, Diamond Green Certificate if they comply with at least 6.4 Guidelines (i.e. 80% of the Guidelines relevant to your industry), for example Guidelines 2, 4, 5, 6, 8, 10, and 40% of Guideline 15.

If, after going through the contents of this page, you still have questions or queries left (for example regarding which particular Guidelines are relevant to your business), you are welcome to write to us at info@piazzasmart.com. As a seller, if you see that your products or services do not meet any of the 15 Guidelines below, but you believe they do incorporate ethical practices not mentioned here, you are welcome to advertise them in your listings as you see fit, but without using the Piazza Smart Certificate.

The Guidelines Are Flexible

We want to make life as easy as possible for sellers, so our Sustainability Guidelines are flexible. This means that, as a seller, you can become compliant by fulfilling one Guideline by 50% and another Guideline by 50%. Or perhaps one Guideline by 40%, another by 30% and yet another by 30%. It's up to you. For example, your product will be entitled to our Topaz Orange Certificate if it uses 20% renewable energy (Guideline no. 4), 15% recycled raw materials (Guideline no. 5), and a 6% increase in water efficiency (Guideline no. 9).

Please note that Guidelines may overlap with one another. Therefore, things you do to comply with one Guideline must be additional to, and not identical with, things you do to comply with another Guideline, if you want them both to count for your Certificate.

For example, you may not claim as a seller that you comply with Guideline no. 2 and 6 at the same time if all you do is use 20% less raw materials in your products. In this case, we suggest you indicate Guideline no. 2 if you have a 20% carbon reduction quantified by an independent provider, and Guideline no. 6 otherwise. However, if you both use 20% less raw materials AND produce locally within 100 miles, you may claim compliance with both Guidelines in your Certificate.

Similarly, if you are a reseller and your products are made with 50% recycled materials (Guideline no. 5), you may not claim that they also meet Guideline no. 15 because your suppliers sell you products made with 50% recycled materials. You may, however, claim that your products also meet Guideline no. 15 if a supplier of yours uses 50% pre-owned equipment.

And now, let's get to explore the individual Guidelines that make up our concept for the future of shopping.

---

Sustainability Guideline Number 1 – Solutions for Eco-Conscious Lifestyles and Business

To meet Guideline no. 1, items you list on our website as a seller must be included in the list of eco-conscious items below.

The list below is exhaustive – a seller cannot claim that their item fulfils Guideline no. 1 if it's not included in the list. However, if you have more items in mind on top of those listed below, please write to us at info@piazzasmart.com, and we will consider expanding the list. Some of the items in the list may not differ per se from conventional ones in terms of their production process or materials, but they will certainly have a reduced impact on the environment if they are used in place of their traditional plastic or animal-based counterparts.

We include in the list below items which are predominantly made of eco-friendlier materials than traditional plastics, synthetic fibres, or even cotton. We include items enabling water, energy or CO2 savings. We include items having a positive impact on health or society, or offering some other benefit compared to their traditional counterparts.

• Items made at least 80% of one or more of the following materials: bamboo, cork, flax, hemp, jute, grass, maize starch, bio epoxies, bioresins, bioplastics and other biodegradable materials; paper, cardboard and timber from well-managed forests; lead-free glass; ceramics; recyclable metals (steel, aluminium, tin, iron, copper, brass, zinc; precious metals are excluded); mushroom leather and other non-animal leather products (excluding fossil fuel-derived leather)*
• Vegan products (excluding apparel, and products using palm oil): for example, vegan food and recipes (even if sold as paper books), makeup and body care products (which should additionally not be tested on animals), accessories, detergents, glues and other items; these products do not need to come with a separate Vegan certificate
• Lab-grown diamonds and other gemstones (including the frames they are mounted on)
• Certified conflict-free gemstones and precious metals
• Liquid soap sold in powder form (water to be added by the buyer)
• Toothbrushes made of bamboo, maize starch or other biodegradable materials, or toothbrushes that require changing heads only; solid toothpaste and shampoo, or toothpaste sold in lead-free glass pots
• Mineral water and other beverages sold in 100% recycled plastic or lead-free glass bottles, recyclable metal cans (for example aluminium or tin cans), or cartons from well-managed forests
• Merchantable food sold in the context of an anti-food waste programme
• Water/air purifiers and filter systems
• Tap aerators, low-flush toilets, dual-flush toilets, water recycling systems, rainwater harvesting systems
• FSC-certified products or other paper/timber from well-managed forests
• E-books
• VOC-free alternatives to conventional items
• Mineral (NOT chemical) sunscreens
• Folding fans
• Swamp coolers, dehumidifiers, CO2-based or hydrocarbon-based air conditioners
• Heat insulation mechanisms, cogeneration systems, three-layer windows and in general systems designed to make buildings more efficient
• Renewable energy systems and their components, such as solar panels, wind turbines, geothermal systems, and energy storage systems
• Multi-purpose products (i.e., products serving more purposes than conventional ones)
• Bicycles
• Electric vehicles and powered transporters, such as electric cars, mopeds, scooters, bicycles, unicycles, hoverboards
• Parking spot finding services
• Exercise bikes and other equipment that are self-powered
• Radiator reflector panels
• Infrared heaters
• Water-based glues and stains
• Composters
• Grow systems
• Chemicals allowed in organic farming
• Vegetable inks, and paper material using vegetable inks
• Biofuels
• Menstrual cups
• Reusable pads and diapers
• Products and services for animals which are meant to promote animal welfare better than conventional ones
• Cruelty-free alternatives to conventional animal products (e.g. silk made with farming practices where larvae are not killed; cultured meat and dairies; please note that products which are simply not tested on animals do not meet this requirement per se)
• Verifiable carbon offsets
• Fair Trade labelled items
• Items for which at least 10% of the revenue goes into verifiable environmental, social or economic sustainability programmes (e.g. empowering women, people with disability, BIPOCs, economically disadvantaged individuals, etc.)

• If your items are made 40% of one of the materials listed in the first bullet point of this Guideline, and 50% of recycled materials or scraps, as set out in Guideline no. 5, they will be compliant with both Guidelines. Your items will also comply with both Guidelines if they are made 80% of one of the materials listed in the first bullet point of this Guideline, and 20% of recycled materials or scraps.

Sustainability Guideline Number 2 – Reduced Net Carbon Emissions

To meet Guideline no. 2, items you list on our marketplace as a seller must only be products and services for which you have calculated your business's carbon footprint and offset it by at least 50%.

Alternatively, to meet Guideline no. 2, items you list on our marketplace as a seller must only be products and services for which you have calculated your business's carbon footprint and reduced it by at least 20% compared to current standard industry practice, or to your own previous practice in a reference year.

We want sellers to list on our marketplace products and services with a reduced impact on the climate compared to traditional solutions. To do this, the first thing you need to do as a seller is calculate your item's carbon footprint, or have it calculated by a credible certifier (one who is not known to have been involved in frauds and who takes a serious approach to the matter–scandals are common in the carbon calculating and offsetting industry).

The carbon footprint is the release of greenhouse gases (GHG) into the atmosphere. GHGs include CO2 (e.g. from combustible fuels used to power a car, make a product or produce electricity), methane, nitrous oxides, CFCs, HFCs, PFCs (these are commonly used as refrigerants), sulphur hexafluoride, and nitrogen trifluoride. You can use as a reference the GHG Protocol and UK government guidance.

Then, you will need to offset or reduce your item's carbon footprint. You won't need to offset or reduce your carbon footprint resulting from: your other products; your suppliers for products you offer on Piazza Smart; transport of your products to Piazza Smart customers (unless it is carried out by your own business).

The carbon footprint of a product or service can be lowered by means of carbon offsets or carbon reductions. Carbon offsets are the simplest way to make your items more sustainable, and they are also a good start if you haven't got any previous experience doing eco-conscious business, because they don't require you to change your business processes. They also make a good complement to other, more effective measures.

Ways in which you can offset your carbon footprint include, among others:

• Buying certified carbon offsets from a credible vendor
• Financing a credible forest conservation or tree-planting project
• Financing a renewable energy company or installation project
• Funding community projects aimed at reducing carbon emissions or improving energy efficiency
• Funding energy communities
• Funding a waste-to-energy project, whereby methane coming from landfill gas or human/agricultural waste is converted to energy

In particular, you will need to make sure that your carbon offsets are quantifiable and "additional". "Additional" means that the offsetting project you are funding would not have progressed if you hadn't paid for it. For example: the waste-to-energy project you are paying for would have gone forward anyway due to new regulations coming into effect; in this case, your offset is not additional and it will not count for your Piazza Smart Certificate.

Another example: the wind farm installation project you're paying for has been implemented on purely economic grounds, because renewable energies are becoming cheaper than fossil fuels and are a profitable investment per se; in this case, your offset is also not additional and it will not count for your Piazza Smart Certificate.

Carbon offsets have the disadvantage of being less effective against climate change than are other measures, such as carbon reductions. To implement carbon reductions, you will also need to calculate your item's carbon footprint (or engage a credible certifier to do it), and then take quantifiable steps to reduce it. There are all sorts of things you can do to reduce your carbon footprint in order to meet this Guideline (including taking steps suggested in other Guidelines on this page). Below are a few examples.

If you're a manufacturer or artisan, one way to reduce your item's carbon footprint is to have the production process take place locally, where "locally" means within a limited area (say, 100 miles). If you source your raw materials and package the finished product locally, you will avoid releasing vast amounts of CO2 and pollution into the environment, because you won't have to transport materials from one corner of the globe to the other.

This is why, if your item's production process (from raw materials sourcing to storage of the packaged product) takes place within 100 miles of distance, it will be automatically compliant with Guideline no. 2. You won't even need to calculate your item's carbon footprint. "Within 100 miles of distance" means that raw materials, semi-finished products, finished products and packaging must not travel more than 100 miles in total before they are sold. You can rely on remote workers located more than 100 miles away in your production process, provided all they do is provide deliverables in electronic (and not physical) form.

Other ways of reducing your carbon footprint include consistently relying on: (1) remote work in place of work commutes; (2) video conferencing in place of business trips; and (3) cloud services in place of in-house IT infrastructure. If you meet all 3 these requirements in relation to your Piazza Smart item, it will be automatically compliant with Guideline no. 2. If not, you will need to quantify the carbon reductions.

Please note, however, that if relying consistently on remote work, video conferencing or cloud services is already standard in your industry (as is the case, for example, if you are a freelance translator), these practices won't count for your Piazza Smart Certificate.

If, as a seller, you work from home and you haven't got your own office, shop or practice, this will also make your item automatically compliant with this Guideline (unless it is already standard in your industry to do so). An office provided by a client of yours doesn't count as your own office.

Other ways of reducing your carbon footprint include: switching to ultra-low emission vehicles (ULEVs), using public transport, implementing a cycle to work scheme, providing for vegan meals or vegan days if you run a food service for the workplace.

As a seller, when you determine your item's carbon footprint, you must also consider your wider business's activities that apply to all your items. For example, if your administration department has an annual carbon footprint of 20 tonnes of CO2eq (even though it is not directly involved in making or selling the product), and your business has 10,000 individual units of products it can sell every year, you must divide 20 tonnes by 10,000 and add the result to the product's own carbon footprint. This will result in a more realistic calculation of your item's impact on the climate.

This Guideline is flexible. This means you can become compliant by meeting, for example, 50% of the first requirement outlined in bold at the top of this section and 50% of the second requirement. For example, you can become compliant by offsetting emissions from your item by 25% AND reducing them by 10%. You can use any proportion of offsetting and reduction you want in order to meet this Guideline.

Sustainability Guideline Number 3 – Pre-Owned and Vintage Items

To meet Guideline no. 3, items you list on our marketplace as a seller must be second-hand, refurbished or vintage products and services.

Pre-owned items are among the most sustainable products around, because they don't go through the production process. This is why we want sellers to list on our marketplace pre-owned items in search of a new owner who can value them as they deserve – a new consumer, a new user or business buyer, or a vintage collector.

As a seller, you need to make sure your pre-owned items are of merchantable quality and comply with all applicable regulations (including regulations regarding cultural heritage). For example, food, cosmetics, body care items and health products must come in their original unopened package and be sold before their "best before end" date. Also, make sure to describe the item's condition fully and accurately.

---

Sustainability Guideline Number 4 – Renewable Energy

To meet Guideline no. 4, for items you list on our marketplace as a seller, you must power your business using at least 50% renewable energy.

Renewable energies enable substantial reductions in carbon emissions and pollution compared to their fossil fuel-based counterparts. Renewable energy sources include the sun, the wind, hydropower, geothermal energy, wave motion and biogas. Wood is only considered renewable energy if its use demonstrably does not cause forest degradation.

In order to comply with Guideline no. 4, as a seller you need to be able to evidence that at least 50% of your energy supply used for your Piazza Smart item (including power, building heating energy, etc., but excluding fuels for business vehicles) comes from renewable sources.

When you determine your item's energy mix, you must also consider your wider business's activities that apply to all your items. For example:

• Your utility bills evidence that your item is made with electricity coming 70% from renewable energy
• Your business has 10,000 individual units of products it can sell every year, and your production department consumes 200,000 KWh of electricity in a year; if you divide 200,000 by 10,000, you will get how much electricity goes into a single item at 70% renewable energy (i.e., 20 KWh)
• Your utility bills evidence that your building heating energy comes only 30% from renewable energy and amounts to 50,000 KWh in a year; if you divide 50,000 by 10,000, you will get how much heating energy is consumed for a single item at 30% renewable energy (i.e., 5 KWh; if heating is measured in cubic feet, you can convert all into joules for the purpose of the calculation)
• Your administration and other departments (even though they are not directly involved in making or selling the product) have an annual global energy consumption of 40,000 KWh (i.e., 4 KWh per single item) at 50% renewable energy
• So the proportion of renewable energy for a single item you offer on Piazza Smart will be: ((20 KWh0.7)+(5 KWh0.3)+(4 KWh*0.5))/(20 KWh+ 5 KWh+ 4 KWh)= 17.5/ 29= 0.6= 60%

---

Sustainability Guideline Number 5 – Recycled Raw Materials or Equipment

To meet Guideline no. 5, items you list on our marketplace as a seller must be made at least 50% of recycled materials or scraps.

Alternatively, to meet Guideline no. 5, at least 50% of your equipment (including computers, smartphones and other devices, printers, lamps and other office appliances, office furniture, manufacturing machinery, company cars and the like) used in relation to items you offer on Piazza Smart as a seller must be pre-owned, refurbished or recycled.

If your items are made 50% of recycled materials or scraps, and 40% of one of the materials listed in point 1 of Guideline no. 1, they will be compliant with both Guidelines. Your items will also cover both Guidelines if they are made 80% of one of the materials listed in point 1 of Guideline no. 1, and 20% of recycled materials or scraps.

---

Sustainability Guideline Number 6 – Reduced Raw Materials or Equipment

To meet Guideline no. 6, items you list on our marketplace as a seller must be made with 20% less raw materials compared to current standard industry practice, or to the manufacturer's previous practice in a reference year.

Alternatively, to meet Guideline no. 6, your equipment (including computers, smartphones and other devices, printers, lamps and other office appliances, office furniture, manufacturing machinery, company cars and the like) used in relation to items you offer on Piazza Smart as a seller must be at least 20% reduced in amount (compared to standard industry practice, or to your own previous practice in a reference year), or older than 7 years.

---

Sustainability Guideline Number 7 – Efficient Production Management

To meet Guideline no. 7, items you list on our marketplace as a seller must be made to order, in small batches or just-in-time.

One of the most effective ways to reduce carbon emissions, as well as waste and pollution in general, is going straight to the source – by avoiding unnecessary production. This is why we want sellers on our marketplace to meet demand for products with efficient approaches such as just-in-time.

---

Sustainability Guideline Number 8 – Enhanced Energy Efficiency

To meet Guideline no. 8, for items you list on our marketplace as a seller, you must improve the energy efficiency of your business by at least 20% compared to current standard industry practice, or to your own previous practice in a reference year.

We want sellers to adopt measures to make their business more energy-efficient. Examples include heat insulation mechanisms, cogeneration systems, more efficient machinery and electronic devices, reduction of fuel leaks and spills, LED lighting, and the use of public transport and district heating systems. You can also adopt timed systems to prevent energy waste in the workplace, move to smaller premises, or make sure that heat can circulate freely in the office and in the absence of open windows.

As a seller, you must calculate your business's energy efficiency across all types of energy consumption that are relevant to your Piazza Smart items, including power, heating energy, business vehicles etc. Your calculation must also include departments that are not directly involved in making or selling the item, such as the administration department and the legal office.

One way to improve the energy efficiency of the production process is by selling hand-made products. These are eco-friendly in that they require minimum equipment and power to create. In addition, they empower individuals and communities to earn a living with their manual skills, and thus contribute to making our economic system more sustainable at a social level. This is why any hand-made products made with no use of electricity, or with tools which only consume very minor amounts of power, will be automatically compliant with this Guideline (no calculations needed).

---

Sustainability Guideline Number 9 – Enhanced Water Efficiency

To meet Guideline no. 9, for items you list on our marketplace as a seller, you must improve the water efficiency of your business by at least 20% compared to current standard industry practice, or to your own previous practice in a reference year.

Water is bound to become an increasingly scarce resource. This is why we want sellers on our marketplace to adopt measures to make their business more water-efficient. Examples include water recycling systems, rainwater harvesting systems, reduction of water leaks, tap aerators, less water-consuming production processes, intelligent buildings, and dual-flush and low-flush toilets.

---

Sustainability Guideline Number 10 – Reduced Waste, Pollutants or Toxic Chemicals

To meet Guideline no. 10, for items you list on our marketplace as a seller, you must calculate your business's production of one type of waste (it can be solid waste or wastewater, or hazardous waste, or POPs waste, or electronic waste, or fuel waste, or harmful gases released into the atmosphere such as dioxin; greenhouse gases are expressly excluded, as they are addressed in Guideline no. 2) and reduce it (or reduce its toxicity) by at least 20% compared to current standard industry practice, or to your own previous practice in a reference year.

This Guideline is flexible. This means you can become compliant by reducing, for example, solid waste by 10% AND electronic waste by 10%. Or perhaps solid waste by 5%, wastewater by 5%, hazardous waste by 5%, AND harmful gases by 5%.

As a seller, you will automatically become compliant with this Guideline (no calculations needed) if you participate in external pollution reduction programmes, for example by cleaning up tracts of coastline from waste, by collecting substantial amounts of plastic from the oceans, or by restoring degraded soil or ecosystems.

If you want to meet this Guideline the standard way, you will need to track your business's waste. Zero Waste Scotland offers guidelines on how to do it.

You must calculate your business's waste across all sources that are relevant to your Piazza Smart items. You must include in the calculation, for example, waste from business vehicles and departments that are not directly involved in making or selling the item, such as the administration department and the legal office. For example, if your administration department produces 50 tonnes of solid waste per year and your business has 10,000 individual units of products it can sell every year, you must divide 50 tonnes by 10,000 and add the result to the solid waste produced for a single item you offer on Piazza Smart.

A few examples of measures you can take to comply with Guideline no. 10 are:

• Avoiding waste to be created in the first place (e.g., by using less materials, repairing broken equipment, or re-purposing discarded items)
• Reducing disposable items used in your business activity (e.g., coffee cups, cutlery and dishes)
• Reducing leaks and spills of water, fuel or other fluids (e.g. due to defective plumbing)
• Switching to biodegradable materials or easily recyclable monomaterials
• Recycling your discarded parts into the manufacturing process
• Embracing additional manufacturing (3D printing) in place of traditional subtractive techniques
• Using waste substances (such as tall oil or cooking oils) instead of virgin substances in your production process
• Switching to rechargeable batteries
• Switching to digital documents in place of physical ones
• Using refillable ink cartridges in printers, printing on both sides of the page, and using draft quality
• Reselling your electronic and other equipment instead of disposing of it
• Enabling and encouraging the separate collection of waste in the workplace
• Implementing an anti-food waste programme
• Implementing a restricted substance policy in your business, replacing harmful chemicals with less toxic ones wherever possible (or using, for example, a paste form instead of a powder form of the substance)

You can also become compliant by making sure your products and production processes do not involve the use of toxic chemicals normally present in conventional products and production processes. Toxic chemicals are, for example, endocrine disrupting chemicals like BPA, heavy metals like lead, ozone depleting substances, aerosols (see for example the Cradle to Cradle Institute, the SIN List and REACH).

A non-exhaustive list of toxic chemicals is present in slide 8 of this document. Please note that PFCs are now called PFAS and are common e.g. in outdoor apparel. In the fashion industry, for example, substances to avoid include PFAS and formaldehyde, and unacceptable production processes include sandblasting of denim garments. For furniture and other industries, it's a good idea to avoid VOCs.

You should also clearly explain to your customers how to dispose of your product once it is no longer used.

Sustainability Guideline Number 11 – Use of Eco-Conscious Packaging

To meet Guideline number 11, for items you list on our marketplace as a seller, you must use packaging made at least 90% of recycled materials or other kinds of eco-conscious materials (e.g. lead-free glass; biodegradable materials; paper, cardboard and timber from well-managed forests; ceramics; recyclable metals such as aluminium, tin, steel, copper, iron, brass, zinc – precious metals are excluded; mushroom leather and other non-animal leather products, excluding fossil fuel-derived leather).

Alternatively, to meet Guideline number 11, for items you list on our marketplace as a seller, you must reduce materials used for packaging by at least 30% compared to standard industry practice, or to your own previous practice in a reference year.

"Packaging" is taken here to mean the box or bottle containing the product (excluding the label). To reduce the amount of materials used, you can for example:

• Insert larger quantities of product per package
• Design your package so as to minimise the need for materials (e.g. single-layer instead of multi-layer package)
• Sell your products loose or by measure
• Use a refillable packaging model
• Provide multiple use packaging
• Offer a packaging buyback or a two-way container policy

---

Sustainability Guideline Number 12 – Extended Product Life

To meet Guideline number 12, for items you list on our marketplace as a seller, you must offer incentives to your customers to extend product life, such as a repair service, an extended (non-optional) warranty, a trade-in or take-back policy, a product buyback, or opportunities to resell or re-purpose products.

Alternatively, to meet Guideline number 12, you can offer your products on our marketplace on a rental, sharing or PaaS (Product-as-a-Service) basis instead of selling them. Any rental service (excluding real estate and aircraft rental) will be automatically considered compliant with this Guideline.

Any measure you take as a seller to prevent consumed products from becoming waste will make you compliant with this requirement. Just unleash your creativity. You can have products rented and shared instead of sold and consumed, or returned back to you to be reutilised in the production process. You can design your products so that they are easy to disassemble and re-use. You can also become compliant by donating all unsold items to trusted charities. Circular design and longer lasting pieces, avoiding planned obsolescence, can also be part of this strategy.

The measures you take must in any case be demonstrably effective in extending product life compared to current standard industry practice, or to your own previous practice in a reference year.

---

Sustainability Guideline Number 13 – Plant-Based Materials

To meet Guideline number 13, for items you list on our marketplace as a seller, plant-based materials must come from either organic or integrated farming, and be at the same time palm-oil free. Wood, cardboard and paper products (excluding packaging) must come from well-managed forests.

Plant-based products include fruit, vegetables, cotton, flax, hemp, straw, wood, wood pulp, cardboard, paper, etc. High levels of pesticides in farming are harmful to human health, and are bringing bee populations on the verge of extinction. Bees are responsible for about one third of vegetable food production. This is one reason why we want sellers to list on our marketplace items using pesticides sparingly, as is the case in organic and integrated farming.

"Integrated farming" is taken here to mean farming practices that minimize impact on the environment and consumer health, e.g. as defined in the UNI11233-2009 European standard. We don't require all plant-based products to be organic for this Guideline to be met, because organic farming presents its own downsides due to its reduced yields, which would make feeding humans with this type of agriculture an impossible challenge.

Thus, as a seller you need to self-certify that your plant-based materials come from organic or integrated farming. They must also be palm oil-free. Palm oil is widely used as a conventional ingredient in many industries, but oil palm farming is bringing about the destruction of tropical rainforests and is therefore unsustainable.

---

Sustainability Guideline Number 14 – Animal-Based Materials

To meet Guideline number 14, for items you list on our marketplace as a seller, animal-based materials must come from either organic or integrated farming, and be at the same time cruelty-free and use antibiotics sparingly.

Animal-based products include meat, dairies, wool, leather, etc. Organic farming reduces to a minimum the high levels of antibiotics and hormones used in conventional animal husbandry, which are harmful to human as well as animal health and increase the risk of antibiotic-resistant outbreaks of infections. This is one reason why we want sellers to list on our marketplace items using antibiotics sparingly, as is the case in organic farming.

"Integrated farming" is taken here to mean farming practices that minimize impact on the environment and consumer health, e.g. as defined in the UNI11233-2009 European standard. We don't require all animal-based products to be organic for this Guideline to be met, because organic farming presents its own downsides due to its reduced yields, which would make feeding humans with this type of agriculture an impossible challenge.

To meet this Guideline, animal husbandry should also comply with responsible practices concerning animal welfare, i.e. animals should not be subjected to factory farming, maltreatment, or used for product testing. They should have a free range available for at least part of the day.

---

Sustainability Guideline Number 15 – Supply Chain Compliance

To meet Guideline number 15, with sole reference to items you list on our marketplace as a seller, you must have at least one supplier complying with any one Guideline among 2 or 4 through 12 above.

Transparency and traceability of the supply chain and its impact on the environment are essential to sustainable business. This is why we want sellers to list on our marketplace items whose suppliers are compliant with at least one of our Guidelines. Such suppliers can be product suppliers, energy suppliers, IT suppliers, or any other kind of suppliers which is relevant in some way to the item offered on Piazza Smart.

As a seller, please bear in mind that your compliance with this Guideline must be additional to, and not overlapping with, compliance with a different Guideline (see the following section for further clarification).

---

Compliance

Different items showcased on Piazza Smart may display different Certificates. As a seller, your listings must reflect their stated Certificate at all times, and you must undertake regular reviews of your Piazza Smart Certificate compliance. Your sustainability claims must also comply with all relevant legislation and regulations, including the CAP Code published by the Advertising Standards Authority and the Green Claims Code published by the Competition and Markets Authority.

As a seller, you should also bear in mind that, for the purpose of using the Piazza Smart Certificate, you cannot take credit for virtuous business practices which are already required by law, or which have been standard in your industry for years. This applies to all Guidelines. You are welcome to make us aware of any challenges you may encounter in becoming compliant with our criteria.

As a seller, you must have proper procedures in place (using self-assessment or external compliance reviews) to verify that the representations you make about the Piazza Smart Certificate are true and provide such information, documentation or evidence to us upon our reasonable request. Failure to comply with these Guidelines will be considered a material breach of our Terms of Service.

Amendments

We may change these Guidelines from time to time. We will notify you if we make a significant change to these Guidelines, by contacting you through the contact details you have provided to us and by publishing an updated version on our website.
