Plastic credit contracts: forward purchases, delivery risk and what to write down

Why the contract matters as much as the credit

A plastic credit is only as reliable as the agreement that delivers it. Many buyers do not take credits off a registry on the day they need them. They sign a contract with a developer or intermediary, pay in advance or on delivery, and receive units months or years later, once collection has been measured and verified. Between signing and delivery, several things can go wrong. The project can be delayed, the verified volume can come in below forecast, or the registry entry can take longer than expected. The contract decides who carries each of those risks.

Forward purchases and delivery risk

A forward purchase fixes a price and a volume today for credits that will be issued from a future vintage. It gives project developers the revenue they need to build collection capacity, and it gives buyers price certainty and early access to supply. The trade-off is delivery risk. A forward contract commits the buyer to paying for credits that may not exist in the quantity or on the timetable that was promised.

Delivery risk has three parts. Volume risk is the gap between contracted and verified tonnes. Timing risk is the gap between the year a buyer needs credits for a report and the year they are actually issued. Quality risk is the possibility that the verified credits do not meet the methodology the buyer relied on. Each part needs its own clause, because a single general warranty rarely covers all three.

Payment terms: advance, milestone or on delivery

Payment structure is the first decision. Full prepayment gives the developer the most working capital and leaves the buyer most exposed, so it suits established projects with a verification history better than new ones. Payment on delivery protects the buyer but may leave the project unable to fund its operations while it waits. Milestone payments sit between the two. They are tied to events such as the issue of a verification report or the registration of a vintage, which gives both sides a clear trigger. Pair milestones with a long-stop date, so that a delayed verifier does not leave either party stranded indefinitely.

What a supply agreement should specify

A workable agreement names the following:

• The standard and methodology, including the version, under which credits will be issued.
• The registry in which credits will be recorded, and the account into which they will be transferred.
• The vintage, the contracted quantity in tonnes or credits, and the minimum acceptable volume.
• The expected delivery date and a long-stop date after which the buyer may cancel.
• The remedy if volumes fall short: replacement from another project, a partial refund, or a price adjustment.
• The retirement arrangements, including the beneficiary name and the date by which retirement will be made.

Protective clauses buyers often overlook

Three clauses deserve particular attention. The first is a double-counting warranty, under which the seller confirms that each credit has not been claimed or sold to another buyer. The second is a reversal provision that sets out what happens if collected material is later mismanaged. The background is in reversal risk in plastic credits and how double counting is prevented. The third is data access. The buyer should be entitled to the monitoring data and verification reports behind the credits, so that its own disclosure can be checked rather than taken on trust.

Force majeure and termination

Define force majeure precisely. Events outside the developer's control, such as a flood that halts collection or a regulatory suspension of a waste site, may justify a delay. A project's own failure to run its operations properly generally should not. Include a termination right for persistent under-delivery, and state clearly whether unused advance payments are refunded and within what period.

Checking the counterparty before signing

A contract is only as strong as the organisation behind it. Check the developer's track record, whether the project has been verified before, which verification body has audited it, and whether the public project page shows the information a buyer needs. The steps are set out in our guide to evaluating a plastic credit project.

Accounting and disclosure

Contract terms also affect how credits appear in financial statements and sustainability reports. Prepayments, forward commitments and retired credits may each be treated differently, and the treatment depends on the reporting framework and the facts of the deal.

Frequently asked questions

Should I pay in advance for plastic credits?

Only when the price discount outweighs the risk, and usually only for projects with a verification history. If you do pay in advance, make the refund right explicit and tie it to a date.

What happens if a project delivers fewer credits than contracted?

The contract should set the remedy in advance, whether that is replacement, a partial refund or a price adjustment. Without one, the buyer may have no clear route to recover the shortfall.

Do I need a lawyer to review a credit supply agreement?

For any material purchase, yes. This article describes common commercial terms and is not legal advice. Counsel should check the wording against your jurisdiction and your own reporting obligations.
