Technical Explainer: Clean and Improved Cookstove Carbon Credits

This technical guide by RMI analyzes the market, quality risks, and methodological evolution of clean and improved cookstove carbon credits. It details the transition from legacy methodologies, which faced allegations of over-crediting, to newer, more rigorous standards like VM0050 and the forthcoming CLEAR methodology. The document provides a detailed risk assessment, highlighting monitoring, reporting, and verification (MRV) as a high-concern area due to behavioral complexities such as stove stacking and the Hawthorne effect.

• As of August 2025, cookstove projects have issued over 181 million credits, representing 7.6% of all credits issued by the Voluntary Carbon Market (VCM). Gold Standard holds the majority of the market share with over 122 million credits (67.5%), while VCS has issued over 58 million (32.5%).
• Sub-Saharan Africa is the primary region for cookstove credit issuance, accounting for 68.6% of total credits (124,417,687 credits), largely due to high regional fraction of non-renewable biomass (fNRB) values. Kenya, Uganda, and Ghana together account for roughly 34% of all projects.
• Legacy methodologies, specifically CDM's AMS-II.G, Verra's VMR0006, and Gold Standard's TPDDTEC, were responsible for 80% of all cookstove credit issuances. These were criticized for allowing generous assumptions regarding fuel use, stove adoption, and fNRB, leading to allegations of over-crediting and greenwashing.
• The Integrity Council for the Voluntary Carbon Market (ICVCM) has conditionally approved three methodologies for the Core Carbon Principles (CCP) label: GS TPDDTEC v4.0, GS Metered and Measured v1.2, and VCS VM0050 v1.0. Approval is conditional on developers using a conservative 30% fNRB value or deriving one from the MoFuSS model.
• The Comprehensive Lowered Emissions Assessment and Reporting (CLEAR) methodology, developed by the Clean Cooking and Climate Consortium (4C), is intended to be a universal standard for the VCM and Article 6.2 of the Paris Agreement, aiming to set a high bar for MRV and accounting.
• Monitoring, Reporting and Verification (MRV) is identified as a 'High Concern' risk with 'Very Common' prevalence. Key challenges include 'stove stacking' (using both new and old stoves) and the 'Hawthorne effect,' where users change behavior because they are being monitored.
• GHG accounting is a 'Medium Concern' risk. Over-crediting often results from inflated fNRB values based on poor data. To mitigate this, the industry is moving toward the peer-reviewed MoFuSS tool, and TOOL30 is scheduled for withdrawal in 2026.
• Sampling uncertainty is a widespread issue, with some analyses indicating that the majority of cookstove projects monitor less than 1% of distributed stoves. RMI recommends larger sample sizes and stratified random sampling to reduce bias.
• The document identifies several social and environmental co-benefits, including reduced indoor air pollution (lowering respiratory and cardiovascular disease risk), women's empowerment through reduced labor burdens, and forest protection. However, risks include providing stoves that do not match household needs or excluding vulnerable groups.
