Carbon-financed Cookstove Program Failed to Deliver the Benefits in the Field

Replacing traditional cooking fires and stoves in the developing world with "cleaner" stoves is a potential strategy to reduce household air pollution that worsens climate change and is a leading global killer.

A new study by researchers from the University of British Columbia, University of Washington and elsewhere -- which measured ambient and indoor household air pollution before and after a carbon-finance-approved cookstove intervention in rural India -- found that the improvements were less than anticipated.

Actual indoor concentrations measured in the field were only moderately lower for the new stoves than for traditional stoves, according to a paper published in June in Environmental Science & Technology. The study is one of only a handful to measure on-the-ground differences from a clean cookstove project in detail, and the first to assess co-benefits from a carbon-financed cookstove intervention.

Additionally, 40 percent of families who used a more efficient wood stove as part of the intervention also elected to continue using traditional stoves, which they preferred for making staple dishes such as roti bread. That duplication erased many of the hoped-for efficiency and pollution improvements.
