The Market Is Converging on MoFuSS: What It Means for Clean Cooking Carbon Projects in Africa
For years, one number has quietly decided how much a cookstove project is worth on the carbon market: the fraction of non-renewable biomass, or fNRB. It sounds like a technical footnote. It isn't. Overstate it, and a project mints credits for "savings" that were never real forest loss to begin with — a big part of why cookstove credits have taken such a public beating on integrity grounds over the past few years. That's finally changing, and not because of one registry's initiative. Gold Standard retired the old CDM Tool 30 in mid-2025 and let every existing fNRB value expire by the end of that year. The ICVCM has gone further, mandating the more rigorous MoFuSS model across cookstove methodologies market-wide. Verra is now the last major registry catching up, with a public consultation on VM0050 v2.0 open through August 10. The market has converged — the only question left is how ready individual projects are for it.
