Annual PM2.5 air pollution levels in India 2018-2023
Annual particulate matter (PM2.5) concentrations in India averaged 54.4 micrograms per cubic meter of air (µg/m³) in 2023. While annual PM2.5 levels have fallen since 2019, they have still remained more than 10 times above the World Health Organization's recommended limit of five µg/m³. The lowest average annual PM2.5 concentration between 2018 and 2023 was recorded in 2020, when COVID-19-related lockdowns and restrictions had an impact on pollution levels.
