Berkeley Air supported the Gaia Association and the Clean Cooking Alliance to assess the impacts of scaling up ethanol and charcoal briquette programs in the UNHCR refugee camps near Assosa in Western Ethiopia. The primary research goals were to measure changes in carbon monoxide and particular matter in homes after the introduction of an ethanol cookstove and to characterize cookstove usage patterns and perceptions. However the research was ended prematurely due to interruptions in the ethanol fuel supply.
