Technical Explainer: Clean and Improved Cookstove Carbon Credits

The report examines the transition of cookstove carbon credits from legacy methodologies, which faced allegations of over-crediting, to more rigorous, CCP-approved standards. It identifies monitoring, reporting, and verification (MRV) as a high-concern risk due to complex human behaviors like stove stacking and the Hawthorne effect, while highlighting the role of new tools like MoFuSS and the forthcoming CLEAR methodology in improving credit integrity.

• Cookstove projects are a significant part of the voluntary carbon market (VCM), with over 181 million credits issued since 2004, representing 7.6% of all VCM credits as of August 2025.
• Sub-Saharan Africa is the dominant region for these projects, accounting for 68.6% of total credits issued, with Kenya, Uganda, and Ghana representing 34% of all projects.
• Legacy methodologies led to allegations of over-crediting and greenwashing due to inflated fraction of non-renewable biomass (fNRB) values, inaccurate fuel consumption estimates, and the underestimation of stove stacking.
• The Integrity Council on Voluntary Carbon Markets (ICVCM) has conditionally approved three methodologies for the Core Carbon Principles (CCP) label: Gold Standard's TPDDTEC v4.0, Gold Standard's Metered and Measured v1.2, and Verra's VM0050 v1.0.
• The forthcoming CLEAR (Comprehensive Lowered Emissions Assessment and Reporting) methodology is intended to establish a new high-caliber universal standard for cookstove projects in both voluntary and compliance markets.
• Monitoring, Reporting and Verification (MRV) is rated as a 'High Concern' with 'Very Common' prevalence because behavioral factors like the Hawthorne effect and stove stacking complicate accurate emissions estimates.
• To mitigate the risk of inflated fNRB values, the industry is shifting toward the peer-reviewed MoFuSS (Modeling Fuelwood Sustainability Scenarios) tool, and TOOL30 is scheduled for withdrawal in 2026.
• Sampling uncertainty is a widespread challenge, with some analyses showing that the majority of cookstove projects monitor less than 1% of all distributed stoves.
• While GHG accounting and MRV are significant risks, additionality, leakage, and permanence are generally considered low concern and uncommon for cookstove projects.
