China and the US may be the largest producers of coal power, but power plants in India take the highest toll in the world when it comes to health, a global study claims.
Coal-fired power plants produce more than just carbon dioxide, which contributes to global warming, said researchers from ETH Zurich in Switzerland.
Coal burning also releases particulate matter, sulphur dioxide, nitrogen oxide and mercury — thus damaging the health of many people around the world, they said.
To estimate where action is most urgently required, the researchers modelled and calculated the undesired side effects of coal power for each of the 7,861 power plant units in the world.
