Developers of a proposed US peatland carbon methodology have detailed a protocol that would let carbon already stored in drained peat generate removal credits when rewetting prevents its release. Presented in a webinar on Friday, August 21, the approach departs from the avoided-emissions accounting that governs virtually every peatland credit on the market today. If a registry accepts the logic, a meaningful slice of nature-based supply could migrate from the avoidance bucket into the removal bucket, and that reclassification has direct consequences for how buyers build their portfolios.
What the Proposal Actually Claims
Conventional peatland crediting works on a flux basis. A drained peatland emits CO2 as the exposed peat oxidizes; a project that raises the water table stops or reduces that flow, and the resulting credits are accounted as avoided emissions or emission reductions. The carbon still sitting in the ground is treated as a stock that was never released, not as something removed from the atmosphere.
The proposed US methodology, as described by its developers, challenges that boundary. Under its logic, when rewetting prevents the release of carbon that drainage had put on a path to the atmosphere, the preserved stock can be credited as a removal. That is a categorically different claim: not “we stopped an emission” but “we delivered a removal outcome.” The distinction may sound semantic. In carbon market accounting, it is anything but.
Why Peatland Credits Are Avoidance Units Today
The current market structure explains why this proposal matters. Peatlands cover roughly 3 to 4 percent of global land surface yet store about 30 percent of the world’s soil carbon. Drained for agriculture, forestry, or extraction, they contribute around 4 to 5 percent of annual anthropogenic greenhouse gas emissions, nearly 2 gigatonnes of CO2 equivalent per year. Meta-analyses synthesized by Project Drawdown indicate that rewetting drained peatlands cuts emissions by an average of about 16.5 tonnes of CO2 equivalent per hectare per year, while protecting intact peatlands avoids roughly 38.6 tonnes per hectare per year.
Despite those numbers, nearly all peatland credits in circulation are classified as avoidance. Verra’s VM0036 covers rewetting of drained temperate peatlands using the GEST approach, which estimates emissions from water table depth and vegetation type. In the US, ACR’s Restoration of Pocosin Wetlands methodology is active for peat soils in the Southeast, and landowners in states such as North Carolina can already access peatland restoration crediting through ACR. In Europe, the UK Peatland Code listed 361 projects covering around 52,000 hectares as of mid-2025, with credits averaging about 25 pounds per tonne in 2024, while Germany’s MoorFutures programmes have seen project pricing from roughly 30 to over 120 euros per tonne.
All of these are avoidance or reduction instruments. The removal label, and the price premium and strategic demand that come with it, has so far belonged to biochar, direct air capture, enhanced weathering, and similar pathways.
The Market Stakes of Reclassification
Demand for removals is being pulled forward by corporate target frameworks. The Oxford Offsetting Principles call for portfolios to shift over time from avoidance toward durable removals. SBTi’s draft Net-Zero Standard 2.0 introduces interim removal factors rising from 28 percent in 2030 to 100 percent by 2050. Buyers planning against those trajectories are already competing for credible removal supply, and nature-based removals are scarce relative to the demand those targets imply.
A peatland methodology that credibly delivered removal classification would expand that supply at prices far below engineered removals. For developers, removal status could unlock premium pricing and offtake interest from buyers who currently screen peatland projects out of their removal allocations. For the market as a whole, it would test where registries and integrity initiatives draw the line between protecting a stock and removing carbon from the atmosphere.
The Integrity Questions Buyers Will Ask
Three questions will determine whether this approach survives scrutiny.
First, permanence. Peat carbon is only preserved as long as the water table stays up. Re-drainage, infrastructure failure, and fire, especially in degraded peat, can reverse the claimed outcome decades after issuance. Any removal classification will raise the bar on monitoring duration, buffer contributions, and legal safeguards against future drainage. Existing peatland frameworks already run monitoring periods of 30 to 100 years for a reason.
Second, the stock versus flux question. Critics will argue that preventing a release is definitionally an avoided emission, and that calling it a removal inflates the climate claim: the atmosphere ends up no cleaner than before the intervention. Proponents will counter that once drainage has committed a carbon stock to oxidation, arresting that process is functionally equivalent to removal relative to the baseline. How registries and bodies like the ICVCM resolve that framing will matter well beyond peatlands, because similar logic could be extended to forest carbon stocks and soils.
Third, double counting and claims. If the same preserved tonne is credited as a removal while also underpinning avoided-emission accounting elsewhere in a project’s inventory, the integrity problem compounds. Buyers should expect questions about how baselines, leakage deductions, and claims language are handled before treating any such credits as removal-grade.
What to Watch
The near-term checkpoints are procedural. The methodology must move from webinar to formal submission, then through the registry’s public comment and scientific peer review process, the stage at which ACR and Verra test exactly this kind of accounting novelty. Watch for which registry takes it up, how peer reviewers treat the removal classification, and whether integrity initiatives weigh in on the stock-versus-flux question.
For buyers and investors, the practical posture is simple. Track the review, but do not reprice peatland supply yet. If the removal classification survives peer review, early offtakes in US peatland projects could become one of the cheaper entries into nature-based removals. If it does not, the episode will still have clarified where the market draws the avoidance-removal line, which is information every portfolio strategy needs.
