EMBEDDED POINT-OF-SALE CONTRIBUTIONS

Merchants and payment platforms can build voluntary contributions to carbon removal into everyday sales. A merchant can set aside a fixed amount per order or a share of revenue, offer customers an optional contribution at checkout, or combine both. The programme collects the money and pools it for removal purchases or project funding, either through an established purchasing partner or contracts arranged by the operator. This gives small businesses and customers a practical way to support projects without negotiating individual supplier agreements. The contribution need not match the sale's emissions. The terms should explain who pays, who is responsible for purchasing and delivery, whether contributors fund future work or receive completed removal units, and what they may claim.

The merchant and platform must decide who pays, whether participation is optional and how consent is obtained. The agreement should distinguish money collected on contributors' behalf from purchases or matching payments that the merchant or operator promises to fund itself. Fees and the share reaching projects should be stated clearly. The operator should publish how suppliers are selected and how carbon accounting, delivery risks and environmental or social impacts are checked. Contributors also need to know who owns any removal units and what happens to refunds, unspent balances and failed purchases. Funding for future delivery should be reported as such. Any claim linking the contribution to the sale's emissions must explain its accounting basis and comply with the law where it is used.

Embedding contributions in existing commerce can reduce the effort required for small businesses and customers to support removals. Aggregation can make dispersed payments usable for project contracts and allow specialist checks on project quality and delivery risk to serve many contributors. Repeated transactions may also broaden awareness of removal activity. The scale and reliability of demand depend on participation, business volumes and procurement terms, rather than assuming every checkout interaction creates a funded tonne or a long-term supplier commitment.

Participation and sales may fall, reducing the money available for contracts the operator has already promised to fund. Processing many small payments can also consume a large share of receipts. Opaque fees, unclear ownership of units or overstated checkout claims can mislead contributors and damage merchants' trust in the programme. If a supplier fails or delivery is delayed, the operator needs an agreed response, such as replacement supply, revised reporting or refunds where the terms provide them. Payment at checkout should not be presented as proof that carbon has already been removed.

The operator should reconcile contributions and fees with purchases, project payments, unspent balances and verified deliveries. Merchant participation, customer understanding and cancellation rates show whether the offer is both usable and accurately understood. Reporting should separate funding collected from removal completed and explain delays or supplier failures. The results can guide changes to the customer offer, portfolio choices and the size of commitments the operator is able to make.

Platforms should design collection and purchasing arrangements with merchants, which choose whether and how to participate. Independent technical specialists can assess project evidence and risks, while suppliers need clear selection and payment terms. Contributors should be able to understand the offer and challenge unclear reporting. Consumer-protection specialists can test the checkout wording, consent process and advertised claims before launch.

Payment platforms, merchants and programme operators implement collection and procurement through commercial or charitable transactions. Philanthropic organisations can operate an equivalent contribution route with suitable payment partners.
