The World Air Quality Report 2024 by Swiss air quality technology company IQAir reveals a positive trend in India’s air quality, despite ongoing challenges. India now ranks as the fifth most polluted country globally in 2024, a notable improvement from its third-place ranking in 2023. The country also recorded a 7 per cent decline in PM2.5 concentrations, which dropped from 54.4 micrograms per cubic metre in 20 23 to 50.6micrograms in 2024. 13 of the world’s 20 most polluted cities are in India, including Byrnihat, Delhi, and Faridabad. Air pollution remains a significant health concern, with an estimated 1.5 million deaths annually linked to PM1.5 exposure. Experts emphasise the need for continued and increased action to combat air pollution, such as promoting the use of LPG over biomass, expanding public transport, and providing stronger subsidies for low-income families could further reduce pollution and improve public health. The report was released on March 11, 2025.
