Key facts:
A third of the world's population, or around 2.4 billion people, cook over open flames or inefficient stoves powered by coal, kerosene, and biomass, which includes wood, animal dung, and agricultural waste. This causes dangerous air pollution in homes.
An estimated 3.2 million deaths annually, including over 237 000 deaths of children under the age of five, were attributed to household air pollution in 2020.
Every year, 6.7 million premature deaths are attributed to the combined impacts of household and ambient air pollution.
Exposure to household air pollution causes noncommunicable diseases such as chronic obstructive pulmonary disease, ischemic heart disease, stroke, and electricity, biogas, liquefied petroleum gas (LPG), natural gas, alcohol fuels, and biomass stoves that meet WHO emission guidelines.
