A Proposed Methane-Removal Credit for Forest Projects
Forests remove methane from the air through their bark. SelvaFlux measures that uptake and is developing a crediting module for eligible 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.
The separate GWP* scenario represents a newly established methane sink and assumes full mature-forest uptake from the first modeled year. It produces about 1.81 tCO₂-we / ha / year in years 1 to 20 and 0.11 tCO₂-we / ha / year after year 20. No registry currently uses GWP* for crediting. The full calculations are on the impact page.
Credit structure
Proposed Credit Structure
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. Under an approved method, these measurements would support a project estimate with stated uncertainty for an independent auditor to review.
Project-Attributable Uptake
The host project must demonstrate a forest outcome relative to an approved baseline. A future methane method would separately determine which measured methane removal is attributable to that outcome.
Registry Rules Would Apply
An approved methane credit would be subject to baseline, additionality, permanence, leakage, and double-counting rules. The final requirements would come from the approved methane method and the host project’s methodology.
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 Measurements of Bark Methane Uptake
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. We will contact people who register interest if issuance becomes possible.
