Global Inequity Fueled by Indoor Air Pollution

Household air pollution, primarily from cooking fires, results in millions of premature deaths each year globally. A recent study analyzing data from 1990 to 2021 across 204 countries reveals a significant global inequity in exposure and health consequences. While wealthier regions have experienced reduced exposure, many communities in sub-Saharan Africa and south Asia remain heavily reliant on polluting solid fuels like wood and dung.

The health impacts are severe and wide-ranging, including increased risks for chronic obstructive pulmonary disease, stroke, respiratory infections, and lung cancer. Childhood exposure is linked to impaired cognitive development and long-term health disadvantages. These effects are often hidden, contributing to their neglect.
