The study by Greenpeace comes as Delhi's pollution level climbed to severe with an AQI of 401 on Tuesday as a thick haze engulfed the city on Tuesday.
As Delhi continues to choke on rapidly deteriorating air quality, a new study has found that three of the world's largest nitrogen dioxide (NO2) emission hotspots that contribute to formation of finer particulate matter causing air pollution are in India, with one in the Delhi-NCR.
The study by Greenpeace comes as Delhi's pollution level climbed to severe with an AQI of 401 on Tuesday as a thick haze engulfed the city on Tuesday.
NO2 is a dangerous pollutant in itself and also contributes to the formation of PM2.5 and ozone, two of the most dangerous air pollutants.
The largest number of hotspots, a total of 10, is found in China, eight in the Arab world, four in the EU and three each in India, the US and the DR Congo, according to an analysis of new satellite data from June 1 to August 31.
Delhi-NCR, Sonbhadra in Uttar Pradesh and Singrauli in Madhya Pradesh and Talcher-Angul in Odisha are the identified hotspots in India. Sonbhadra and Singrauli are considered as part of a single hotspot.
Air pollution is a global health crisis, with up to 95 per cent of the world breathing unsafe air. With hotspots across six continents, ranging from cities to industrial clusters to agricultural areas, this new analysis shows us more clearly than ever before just how big a part of the picture NO2 pollution is," Lauri Myllyvirta, Greenpeace Nordic air pollution campaigner, said.
The list of the largest NO2 hotspots in the world from June 1 to August 31 this year includes well known coal-fired power plants in South Africa, Germany and India, and numerous coal-burning industrial clusters in China.
METRO TO HELP EASE POLLUTION
- The Shiv Vihar-Trilokpuri Sanjay Lake section of the Pink Line is all set to be opened to public on Wednesday, following which the Delhi Metro will be running 4,749 trips a day, the ‘highest ever’ so far. The 17.86 km-long section is slated to be formally flagged off for passenger.
- In view of authorities taking action Tuesday after pollution level nosedived to severe’, the first time this season, DMRC spokesperson said, “The DMRC will also work on the operationally best possible plan to help ease the pollution situation in the city.”
