Researchers Discover Higher Environmental Impact from Cookstove Emissions

Cookstoves are a central part of millions of homes throughout Asia: families often use readily available and cheap biofuels — such as crop chaff or dung — to prepare the food needed to survive.

Previously, numerous research groups worldwide have shown, mostly based on laboratory experiments, smoke emitted from stoves used for both cooking and heating have a definite, detrimental environmental impact, particularly in India. Despite advances in technology, many people are reluctant or unable to adopt the newer, cleaner cookstoves. For several years, a collaborative team from Washington University in St. Louis has studied the issue and potential solutions. Now, new research gives them a clearer picture of the topic’s true scope.
