Delhi has bent pollution curve, says report

New Delhi: A new report by the Centre for Science and Environment (CSE) has claimed that long-term trend shows Delhi has already bent the pollution curve downwards and the annual level of particulate matter, PM2.5, is declining every year.

Titled ‘Capital Gains-Clean Air Action in Delhi NCR: What next?’, the report lays down a roadmap on what the national capital and NCR towns should be doing to curb air pollution in the region.

The measures to be taken range from changes in cropping patterns to reduce cultivation of paddy to reduce stubble burning to scaling up pedestrianisation in high footfall areas to create low emissions zones.

“The rolling three-year averages, a firmer indicator of change, have reduced by about a quarter since 2014–15… However, even after that decline, Delhi needs more than 60 per cent cut in annual PM2.5 concentration to meet the national ambient air quality standards,” it said.

Multi-sector action has to gather speed, scale, and urgency. This requires strategic shifts to achieve mobility transition, clean energy transition, circular economy at a scale, and clean energy access at a regional scale, the group said.
