This study is a collaboration between SNV and Berkeley Air Monitoring Group to improve access to clean cook stoves for impoverished communities in Cambodia that rely on solid fuels to meet household energy needs. This project also supported the development of a standardized methodology for estimating averted premature death and disability (e.g. averted Disability Adjusted Life Years or ADALYs) from cookstove intervention programs in regions dependent on solid fuels. This study approximated the impact of the ACE-1 and biogas stove programs on health while contributing to the development of a usable validation protocol for cookstove developers based on exposure to PM2.5 household air pollution and outputs from Kirk Smith’s research group’s model, HAPIT (household air pollution intervention tool), to estimate ADALYs.
