A carbon credit offtake agreement is a contract to buy future credits from a project. The buyer gets access to supply, often at an agreed price or formula. The developer gets demand certainty, and sometimes a financing signal that helps raise capital.
Offtakes are useful because many projects need funding before credits are issued. But they also transfer risk into a contract. If the project under-delivers, the methodology changes, validation takes longer or prices move sharply, the offtake terms decide who absorbs the pain.
The key terms
- Volume: fixed annual volume, percentage of issuance or right of first refusal.
- Price: fixed price, floor and upside share, index-linked price or negotiated vintage price.
- Delivery date: when credits must be issued, transferred or retired.
- Shortfall: what happens if the project delivers fewer credits than expected.
- Quality threshold: standard, methodology, vintage, geography, co-benefit or buyer claim requirements.
- Termination: when either party can walk away, and what happens to advance payments.
Fixed price or revenue share?
A fixed price gives certainty but can leave money on the table if the market rises. A revenue share or floating price can preserve upside but may be less bankable for financing. Developers often want flexibility; funders often want certainty. The best structure depends on how much early capital the project needs and how confident the parties are in future market demand.
Delivery risk is the heart of the deal
Most bad offtake outcomes come from over-promising volume or timing. A project may be delayed by validation, monitoring gaps, VVB availability, registry review, host country rules or field performance. The contract should recognise that carbon projects are not factory output. Conservative delivery schedules are not pessimism; they are self-defence.
Before signing an offtake, run low-volume and low-price cases so the downside is visible in the same model as the upside.

Be cautious with broad exclusivity, uncapped replacement obligations, vague quality discretion, aggressive termination rights and pricing that does not reflect delivery risk. If the buyer wants all upside protection and the developer keeps all downside exposure, the agreement is not really a partnership.
