Scenario: a company buys 10,000 carbon credits from a wind project at an agreed price, prepaying 50%. Two years later, the project has issued only 4,000 — the rest “pending verification”. The company lacks credits for its customer-facing neutrality pledge, and the contract… never addressed this case. Prolonged dispute, money lost, reputation lost. The lesson: a carbon credit purchase agreement (ERPA) isn’t an ordinary sale of goods — it carries bespoke risks that generic terms don’t cover.
Why ERPAs are special
Carbon credits are intangible assets tied to future outcomes: at signing, the credits may not exist yet (project underway, pending verification or issuance). Buyers pay today for an asset forming tomorrow — bearing project-failure, verification-failure, or under-issuance risk. Plus, credit value hinges on legal quality (standard, additionality, no double counting) — “junk credits” are worthless in use. ERPAs thus need tailored clauses for these risks, atop the general frame of the 2015 Civil Code and 2005 Commercial Law.
Seven essential clauses
1. Subject matter — credit identification: name the standard (Verra, Gold Standard…), project type, vintage, quantity, project registry number. Specificity prevents “which credits” fights. 2. Price and payment: fixed or formula pricing; how much prepaid, when — tie instalments to issuance/verification milestones, not lump sums. 3. Delivery terms: deadlines, registry transfer mechanics (into buyer’s account or direct retirement in buyer’s name). 4. Seller warranties: the project is real, credits are additional, not double-counted, unencumbered and unsold to third parties — breach triggers damages. 5. Under-issuance risk: what happens if the project issues less than promised — pro-rata price cuts, make-up from other projects, or termination with refund. 6. Force majeure and regulatory change: what if standards change rules, or domestic carbon law shifts destroy the credits’ usability. 7. Dispute resolution: arbitration or courts, governing law — critical for cross-border deals (foreign sellers).
Negotiation notes
Buyers should diligence the project before signing: check standard-registry listings, verification status, developer reputation — never sign on brochure alone. Limit prepayment for unissued credits; milestone-based payment is the best shield. Sellers should be honest about timelines — overpromising leads to warranty breaches and damages dwarfing a modest original deal. Both sides should agree an independent verification mechanism for quality disputes, before escalation.
Conclusion
A carbon credit purchase agreement is a contract for a future asset — so all seven essential clauses (credit identification, price, delivery, warranties, under-issuance, force majeure, disputes) must be tailored to that nature. A good ERPA protects not just the buyer’s money — but the credibility of the “neutrality” claim behind every credit.
