A brand new research carried out by NASA and University of Maryland exhibits that India might quickly change into the world’s high sulphur dioxide emitter.
Sulphur dioxide is produced particularly when coal is burned to supply electrical energy. An air pollutant, sulfur dioxide causes acid rain, haze, and a number of other health-related issues.

India and China are the world’s largest coal shoppers. However, the most recent research – revealed within the journal Scientific Reports on November 9, 2017 – signifies that whereas China’s sulphur dioxide emissions have fallen by 75 per cent since 2007, India’s has spiked by 50 per cent.
China’s capital metropolis Beijing has been a relentless sufferer of extreme smog because of the existence of coal-burning factories and energy crops. However, China’s efforts in the direction of fining polluters, defining emission discount objectives, and decreasing emission limits have confirmed useful for the nation.
Despite China’s 75 per cent drop in sulphur dioxide emissions, the air high quality nonetheless stays poor.
In distinction, India’s sulphur dioxide emissions elevated by 50 per cent within the final decade. India’s largest coal-fired energy plant was opened in 2012 and but it surely nonetheless has to undertake measures and controls like China.

“Right now, India’s elevated sulfur dioxide emissions aren’t inflicting as many well being or haze issues as they do in China as a result of the most important emission sources aren’t in essentially the most densely populated space of India. However, as demand for electrical energy grows in India, the impression might worsen,” says Can Li, an affiliate analysis scientist within the University of Maryland’s Earth System Science Interdisciplinary Center and at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
