What is the greatest source of indoor air pollution in developing countries?

Solid fuels such as biomass and coal used for cooking and heating are the greatest sources of indoor air pollution in developing countries, affecting women and children the most and leading to respiratory infections and millions of deaths annually.

The greatest source of indoor air pollution in developing countries is the use of solid fuels (such as biomass and coal) for household cooking and space heating. This method of cooking and heating is typically done on open fires or stoves without chimneys, which leads to significant indoor air pollution and the potential for serious respiratory infections. Women and children in developing countries are especially affected by this exposure, as they spend more time within the household where such pollutants are prevalent.

It is estimated that half of the world's population relies on these solid fuels. The resulting indoor air pollution is responsible for over 1.6 million deaths per year and accounts for 2.7% of the global disease burden. Children under the age of five, who are more susceptible to harmful pollutants, constitute roughly half of the deaths associated with the indoor use of solid fuels.
