Assessing the climate impacts of cookstove projects: issues in emissions accounting
This paper examines methodological challenges in gauging the emissions reductions associated with cookstove projects. An estimated 2.6 billion people rely on traditional biomass for home cooking and heating, so improving the efficiency of household cookstoves could provide significant environmental, social and economic benefits. According to the paper, carbon finance offers a policy mechanism for realising some of this potential and could also bring improved monitoring to cookstove projects. However, there are formidable methodological challenges in estimating emission reductions. This paper evaluates the quantification approaches to three key variables in calculating emission impacts: biomass fuel consumption, fraction of non-renewable biomass and emission factors for fuel consumption. The analysis draws on a literature review as well as on interviews with technical experts and market actors, and identifies lessons learned and knowledge gaps.
