Per the Central Pollution Control Board (CPCB), air quality in the India's capital improved in 2019 with the number of good air quality days increasing (from 159 to 182) and the number of bad air quality days decreasing from (206 to 183).
“This is a result of policy change and better enforcement of pollution control measures by all agencies. The number of days meeting air quality standards have also increased. While we are still above the standards annually, there’s gradual improvement every year.” said V K Shukla, head of the CPCB’s air quality management division.
A preliminary assessment by the CPCB also showed the concentration of fine particulate matter (PM2.5 and PM10) has reduced in the air in Delhi as compared to the previous year. In fact, per the CPCB reports, the air quality of the capital has been improving every year since 2016.
While the number of ‘good, satisfactory and moderate’ air quality days increased from 159 to 182, the number of ‘poor, very poor and severe’ days decreased from 206 to 183 in 2019.
Shukla said policy changes, including opening of peripheral expressway around Delhi and closure of Badarpur thermal power station in 2018, shifting industries to piped natural gas and use of BS6 fuel, helped improve air quality. “Our pollution control teams and those of all agencies have been on the ground…Every body is doing their bit to control air pollution,” Shukla said.
