A New Credit for the Methane Forests Absorb

Forests remove methane from the air through their bark. SelvaFlux measures that uptake and is developing a crediting module for existing forest-carbon projects. We estimate that crediting is 1 to 2 years away. Sustainability teams can review the proposed credit and register for availability updates.

Under GWP*, a metric better suited to short-lived gases but not yet approved by registries for crediting, the same uptake represents about 2.1 tCO₂e / ha / yr of near-term climate benefit. We report that value as a possible future case. The full calculations are on the impact page.

What You Would Be Buying

Near-Term Cooling

Methane remains in the atmosphere for about a decade and causes more warming per tonne than carbon dioxide during that time. Removing methane reduces near-term warming while the forest continues to store carbon.

Measured in the Field

The uptake is measured directly at the bark with laser gas analyzers, then scaled across the forest with terrestrial laser scanning. The figure a project is credited on comes from field measurement, with a stated uncertainty an auditor can check.

Adds to Forest Carbon

The methane credit is designed as a module for registry-approved reforestation and forest-carbon methodologies. It would add measured methane removal to the project’s existing biomass-carbon credits.

The Same Safeguards as the Project

The methane is an ongoing sink that lasts as long as the forest does. It carries the same permanence buffer, leakage accounting, and additionality tests as the project’s forest-carbon credits, and it is tied to the same forest.

Credited on the 100-Year Basis

Credits would be issued on GWP100, the 100-year metric registries use today. SelvaFlux reports the larger result from GWP*, a metric for short-lived gases, separately as a possible future case.

Independently Verified

SelvaFlux does not certify its own credits. A registry-approved methodology sets the rules, an accredited third party audits the project, and the registry issues the credit.

Published evidence

Published in Nature, Corroborated Independently

Our 2024 Nature study measured methane uptake through tree bark across upland forests. Other research groups have measured uptake at independent sites. The terrestrial laser scanning methods used to calculate woody surface area are also published.

Status

Methodology Status

We are measuring at pilot sites across the tropics. Gold Standard is considering the crediting concept under NMC 187. Verra’s parallel module, M0423, is on hold pending reassessment in Q1 2027. We estimate that crediting is 1 to 2 years away. Registered buyers will be contacted when issuance becomes possible.
