The Greenpeace Southeast Asia/IQAir AirVisual counter applies an algorithm to ground-level air quality data to calculate the projected cost of air pollution due to PM2.5 and NO2.
Despite having comparatively better air quality because of a strict Covid-related lockdown, air pollution continues to be a serious public health crisis as well as threat to our economy, Avinash Chanchal, climate campaigner at Greenpeace India, said.
"As governments look to rebuild economies, it is more important than ever that investments are directed towards green, just and sustainable sectors of society," he said.
