Need to take on all sources of pollution at regional level to improve

Environment professionals feel there is a requirement to tackle all sources of contamination at the regional level to improve the scenario in Delhi, which has topped the list of world’s most polluted capital cities for the 3rd year on the trot. However, the nationwide capital must not overstate what other states ought to be doing and do its best to manage locally-generated pollution, they said.

In 2020, New Delhi’s average yearly concentration of PM2.5 was 84.1 microgram per cubic meter, more than double the level of Beijing which balanced 37.5 g/m3 throughout the year, according to a report by a Swiss group that determines air quality levels based upon the concentration of the lung-damaging fine particles.

The commercial sector represent more than 20 percent of the PM2.5 concentration in Delhi. Therefore, it is very important that all industries in the whole National Capital Area (NCR) switch to gaseous fuels, Sumit Sharma, Director (Earth Science and Climate Change), TERI, said.In the transport sector, there is a need to enhance the public transportation system, reduce private car use and modernise the fleet, he said.”Another concern is the dependence on biomass fuels outside Delhi. To eliminate it, there is a need to provide subsidised LPG to the poorest of the bad,” Sharma said.Dipankar Saha, previous air laboratory chief of the Central Pollution Control Panel (CPCB), stated dust pollution is a major problem in the entire north India.”Around 70 percent of the dust originates from outdoors Delhi, however we can control the staying 30 percent. It will lower toxicity levels and minimize the air pollution-related death rate,” he said. Air contamination caused an estimated 54,000 sudden deaths in New Delhi in 2020, according to a current study by Greenpeace Southeast Asia Analysis and IQAir.”Besides carrying out research, there is an urgent requirement to deal with geography-based info,” Saha said.Santosh Harish, a fellow at the Centre for Policy Research, stated there needs to be a method that tackles all major sources of pollution in parallel, with duties of each local corporation and the federal government plainly defined.”There is a need to deal with pollution at local level and the Commission for Air Quality Management was a crucial action in this direction. Also, Delhi also needs to not overemphasize on what other states need to be doing. There suffices to be done with regards to municipal waste and roadway dust,” he said.The World Air Quality report by Swiss innovation company IQAir, launched on Tuesday, said 22 of the leading 30 most contaminated cities worldwide remain in India.Delhi was followed by Dhaka and Ulaanbaatar in Mongolia. Within South Asia, Indian cities of Ghaziabad, Bulandshahr, Bisrakh, Jalalpur, Bhiwadi and Noida are the top five most polluted regional cities.Reacting to the report, Delhi Environment Minister Gopal Rai on Wednesday said air contamination in the nationwide capital has actually lowered by 15 percent for many years due to the efforts of the AAP government and “it is now as much as the Centre to do its bit”.”Of the leading 10 contaminated cities, 9 remain in Uttar Pradesh. Delhi used to be polluted, but the condition is improving gradually … The reason for this decrease is the consistent and persistent efforts of the Arvind Kejriwal government,” he said.Rai said the AAP federal government brought important policies on fuel modification, tree transplantation, and electrical cars, and set up smog weapons in worse-affected areas.Delhi is the first in the nation to close down its power thermal plants, Rai said.He said that the Centre’s intention is clear, as it has actually done nothing to shut down polluting thermal power plants and brick kilns running in neighbouring states.
