Assessing the Climate Impacts of Cookstove Projects: Issues in Emissions Accounting

The document examines the technical challenges and gaps in accounting for greenhouse gas emissions in cookstove projects, specifically focusing on the Clean Development Mechanism (CDM) and voluntary offset programs. It identifies critical uncertainties in estimating biomass fuel savings, monitoring stove usage, and determining the fraction of non-renewable biomass used. The brief argues that current methodologies often rely on unscientific workarounds, such as using fossil fuel emission factors, and fail to account for significant non-CO2 climate impacts like black carbon.

• Carbon finance is viewed as a mechanism to scale up improved cookstove projects, with the potential volume of credits estimated to exceed 1 billion tonnes of carbon dioxide equivalent (CO2e) per year.
• Cookstove projects primarily utilize the Clean Development Mechanism (CDM) and the Gold Standard for generating offsets, with very limited use of the American Carbon Registry (ACR) and the Verified Carbon Standard (VCS).
• There are three main methods for quantifying biomass fuel savings: the Kitchen Performance Test (KPT), the Water Boiling Test (WBT), and the Controlled Cooking Test (CCT). While the KPT is considered more robust for gauging actual fuel savings, many developers prefer the WBT because it is cheaper and easier.
• Determining the fraction of non-renewable biomass (fNRB) is a major challenge. While the CDM Executive Board issued national default factors for nearly 60 countries in May 2012, concerns remain that these values are based on poor-quality data and ignore local geographic and climatic variations.
• The CDM uses fossil fuel emission factors as a 'workaround' to avoid crediting avoided deforestation, a practice criticized as unscientific that may lead to the under-crediting of projects.
• Current methodologies largely ignore non-CO2 emissions. While the Gold Standard allows credits for methane and nitrous oxide, most do not account for black carbon, despite residential stove interventions offering high net benefits per cost for reducing it.
