RECOGNITION AND SALE OF NON-CARBON OUTCOMES

Public authorities and voluntary standard-setters can establish methods and rules that allow CDR projects to demonstrate and sell valuable outcomes beyond carbon removal. These may include improved water resilience, biodiversity and locally defined social benefits. Recognition can take the form of a verified attribute attached to a removal purchase, a contract buying several outcomes together, or a separately sold credit or payment for an agreed result where the relevant rules permit it. A buyer may be interested principally in watershed protection, habitat recovery or community outcomes, with carbon removal forming another part of the project. The lever enables additional sources of revenue by making those outcomes assessable and claimable.

The authority or standard owner should distinguish an assessment module, a certified outcome and a tradable unit. A module specifies how an outcome is assessed; certification establishes what has been demonstrated; a credit needs rules on ownership, transfer and use. Water outcomes require an identified location, affected users and a measure suited to the benefit being sold. Biodiversity and social outcomes similarly need context-specific indicators, an agreed starting condition and evidence of who benefits. Schemes must decide whether payments recognise maintained conditions or additional improvements, how long commitments last and what happens if results deteriorate. Carbon quantities, storage durability and removal claims must continue to meet their own requirements. Where a project receives several revenues, contracts and registries should identify what each buyer paid for and may claim. Separately selling different outcomes from the same activity, often called stacking, is permissible only where all applicable scheme and legal requirements allow it.

Recognised outcomes could bring water utilities, food companies, conservation funders and other buyers into projects that also remove carbon, even when those buyers have little interest in purchasing tonnes alone. A buyer of removal units could also pay more for demonstrated benefits that meet its own priorities, while a separate results contract could supply an additional revenue stream. This can reward project designs that improve ecosystems and livelihoods alongside removal and make their contribution visible to purchasers. The opportunity is particularly relevant where the same activity produces several valuable outcomes, but it depends on actual buyer commitments and the cost of demonstrating results.

A positive biodiversity or social label can distract from weak carbon accounting or conceal harm in another part of the project. Broad composite scores can hide trade-offs and imply that unlike outcomes are interchangeable. Selling the same improvement repeatedly, overlooking an earlier public payment or promising incompatible claims to different buyers can undermine additionality and create contractual disputes. Revenue forecasts may also overstate buyers' willingness to pay, while ecological assessment and verification absorb much of the proceeds. Rights over land, water, data and revenues can be captured by intermediaries if communities lack a meaningful role. Certification should therefore preserve clear limits on claims and remedies for non-delivery, without implying that a purchase automatically offsets biodiversity damage, water impacts or emissions elsewhere.

The scheme owner should distinguish certified projects and units from contracted purchases, realised prices and money received by land managers or communities. Evaluation should examine which buyers enter because of the non-carbon outcome, whether payments recur and how much revenue remains after assessment, verification and transaction costs. Independent checks should compare promised outcomes with measured change, test allocation across overlapping contracts and identify disputed or withdrawn claims. If labels attract little purchasing, the response may be to simplify costly procedures or revise eligible outcomes. If measured results fail or buyer claims exceed what was sold, issuance and recognition should be corrected or suspended under the scheme's rules.

Ecologists, hydrologists and social researchers should help define measurable outcomes and the limits of comparison across places. Communities, Indigenous rights-holders and land or water users should determine relevant benefits, consent arrangements where applicable and the distribution of revenues. Developers must disclose existing grants, carbon contracts and other claims on the same activity. Prospective buyers should explain which outcome they value and the evidence their purchasing decisions require. Public authorities and standard owners decide recognition and sales rules, while independent verifiers and registry operators check evidence and maintain records that let buyers see what has already been sold.

National and regional authorities can set eligibility and sales rules within their environmental powers, including state-level biodiversity credit regimes. The EU's nature-credit work illustrates a supranational route, with methodologies and governance still being tested. Voluntary standard-setters can operate certification and crediting systems through participant agreements, as in Social Carbon's Nature Stewardship Framework. Public rules determine where voluntary arrangements can be used and which claims or combinations of payments are legally permissible.
