【 摘 要 】

This paper uses a randomizedexperimental design with real-time electronic stovetemperature measurements and controlled cooking tests toestimate the fuelwood and carbon dioxide savings from animproved cookstove program in the process of beingimplemented in rural Ethiopia. Knowing more about howhouseholds interact with improved cookstoves is important,because cooking uses a majority of the fuelwood in thecountry and therefore is an important determinant ofgreenhouse gas emissions and indoor air pollution. Creatinglocal networks among stove users generally appears toincrease fuelwood savings, and among monetary treatments themost robust positive effects come from free distribution.The paper estimates that on average one improved stove savesapproximately 634 kilograms of fuelwood per year or about0.94 tons of carbon dioxide equivalent per year, which isabout half of previous estimates. Using the May 2015California auction price of $13.39/ton, the carbonsequestration from each stove deployed is worth about$12.59. Such carbon market offset revenues would besufficient to cover the cost of the stove within one year.
