India biggest emitter of sulphur dioxide: report using NASA data

India largest emitter of sulfur

• A new report by Greenpeace India shows the country is the largest emitter of sulphur dioxide in the world, with more than 15% of all the anthropogenic sulphur dioxide hotspots.
• This was detected by the NASA OMI (Ozone Monitoring Instrument) satellite.
• Almost all of these emissions in India are because of coal-burning, the report says.
• The Singrauli, Neyveli, Talcher, Jharsuguda, Korba, Kutch, Chennai, Ramagundam, Chandrapur and Koradi thermal power plants or clusters are the major emission hotspots in India.

Why India?

• The vast majority of coal-based power plants in India lack flue-gas desulphurization technology to reduce air pollution.
• In a first step to combat pollution levels, the MoEFCC introduced, for the first time, sulphur dioxide emission limits for coal-fired power plants in December 2015.
• But the deadline for the installation of flue-gas desulphurization (FGD) in power plants has been extended from 2017 to 2022.

NASA data

• The report also includes NASA data on the largest point sources of sulphur dioxide.
• The largest sulphur dioxide emission hotspots have been found in Russia, South Africa, Iran, Saudi Arabia, India, Mexico, United Arab Emirates, Turkey and Serbia.
• Air pollutant emissions from power plants and other industries continue to increase in India, Saudi Arabia and Iran, the report says.
• In Russia, South Africa, Mexico and Turkey, emissions are currently not increasing — however, there is not a lot of progress in tackling them either.

India is the loser

• Of the world’s major emitters, China and the United States have been able to reduce emissions rapidly.
• They have achieved this feat by switching to clean energy sources.
• China, in particular, has achieved success by dramatically improving emission standards and enforcement for sulphur dioxide control.
