The risk of survey bias in self-reports vs. actual consumption of clean cooking fuels

Using a randomized experimental design, real-time electronic stove surface temperature measurements and controlled cooking tests, we estimate fuelwood and CO2 savings from an improved cookstove (ICS) program in rural Ethiopia. Cooking uses a majority of the fuelwood in the country and therefore is a critical determinant of greenhouse gas emissions. Estimating fuelwood savings is therefore a key aspect of crediting ICS climate change benefits....
