New Delhi: India is the world’s largest emitter of anthropogenic sulphur dioxide, which is produced from coal burning, and greatly contributes to air pollution, a study claimed on Monday. According to an analysis of a National Aeronautics and Space Administration (NASA) data released by environmental NGO Greenpeace on Monday, India has more than 15 per cent of all anthropogenic sulphur dioxide (SO2) hotspots in the world detected by the OMI (Ozone Monitoring Instrument) satellite.

The vast majority of plants in India lack flue-gas desulfurization technology to reduce their air pollution, according to the analysis. The NASA data also highlights other hotspots across the globe, with the Norilsk smelter complex in Russia being the largest SO2 emission hotspot in the world, followed by Kriel in Mpumalanga province in South Africa and Zagroz in Iran. However, as per country-wise world rankings, India was found at the top position in emitting SO2 as it has the maximum hotspots. Environment experts called for a strict action on coal power plants. They said these plants should not be given a free hand to continue polluting and causing a health emergency situation in the country.
