Ambient fine particulate matter (PM) is the world's leading environmental health risk factor. Quantification is needed of regional contributions to changes in global PM exposure. Here we interpret satellite-derived PM estimates over 1998-2019 and find a reversal of previous growth in global PM air pollution, which is quantitatively attributed to contributions from 13 regions.

- Fine particulate matter (PM) is a major cause of premature deaths in South Asia, with approximately 1.02 million deaths linked to PM exposure in 2019.
- The main contributors to PM-related mortality are residential combustion (28%), industry (15%), and power generation (12%), with solid biofuels being the largest fuel source (31%).
- The study highlights the significant health benefits that could result from reducing emissions from traditional energy sources, particularly in high PM states like Delhi and Uttar-Pradesh.
