Air pollution is the biggest environmental contributor to mortality and the second-biggest environmental contributor to global disease worldwide. In developing countries, indoor air pollution contributes greatly to this toll. Burning solid fuels in household stoves for cooking and heating not only harms health but also contributes to carbon emissions and climate change. “Stove Change-Out: A ‘Win-Win-Win’ for Development, Environment & Health,” explored a neighborhood-scale stove change-out program to reduce emission of air pollutants by allowing users to shift from conventional stoves to a less-polluting “improved” stove.
Adoption of the new stoves was moderate, with 38 percent of intervention households using traditional and improved stoves at the same time. One of the more common reasons given for this behavior was difficulty cooking certain foods with the new stoves. The researchers found no significant change in fuel wood usage for households using the new stoves. While laboratory measurements of the new stove suggested improved thermal efficiency over traditional stoves, field measurements did not find large changes in fuel usage.
