Supreme Court of India coined the term for the “new and heightened condition of air pollution” in Delhi. And asked the govt to notify a plan to tackle it.
This almost-lethal level of pollution which is beyond the ‘severe category’. The Supreme Court said that ‘health emergency’will be declared if the air quality worsens five times the standard. A health emergency will invite blanket ban on constructions, entry of trucks, and Odd-even scheme implementation in Delhi-NCR.
The threshold for this category (health emergency) will be 300 microgram per cubic metre for PM2.5 and 500 micrograms per cubic metre for PM10. Analysis of past air quality trends shows that ‘severe’ and ‘very poor’ air quality is anticipated throughout the winter from November to February and largely ‘poor’ category during the summer months of March to May.
The plan to combat such heightened level of pollution is prepared by Central Pollution Control Board and approved by the Supreme Court in consultation with noted environmentalist Sunita Narain.
