India is on the verge of overtaking China as the country with the most deaths caused by air pollution, the world’s biggest environmental killer, according to research published on Tuesday.
In 2015 both countries suffered about 1.1m premature deaths as a result of polluted air, with India just 18,000 behind China, the US-based research organisation Health Effects Institute found, making air pollution the fifth-highest cause of death among all health risks.
For years, China has endured more deaths than any other country as a result of exposure to PM2.5 pollution — particulate matter measuring less than 2.5 millionths of a metre in diameter.
