The report notes that a large portion of India’s population, about 1.36 billion people, is exposed to PM2.5 levels higher than the WHO guideline of 5 micrograms per cubic meter. Additionally, 1.33 billion people, equivalent to 96 per cent of the Indian population, are exposed to PM2.5 levels seven times the WHO standard.

This worrying trend can be seen at the urban level, with more than 66 percent of Indian cities having an annual average above 35 micrograms per cubic meter.

The information in this report was collected through a global network of air quality monitoring stations and sensors involving many organizations, institutions, and citizen scientists. The 2023 report has expanded its coverage to include 7,812 locations in 134 countries, while the 2022 report will include 7,323 locations in 131 countries.

According to the report, air pollution remains a serious global issue, causing almost one in nine deaths worldwide.

The World Health Organization estimates that air pollution causes seven million premature deaths every year, with individuals affected by various health conditions such as asthma, cancer, stroke and lung disease. Exposure to high levels of PM2.5 pollution can also impact children’s cognitive development, mental health and aggravate existing diseases like diabetes.
