According to the Centre-run System of Air Quality and Weather Forecasting and Research (SAFAR), the measures against COVID-19 have led to a drop in PM2.5 (fine particulate pollutant) by 30% in Delhi and by 15% in Ahmedabad and Pune, respectively.


  • With a nationwide lockdown in place, over 90 cities, including Delhi, recorded minimal air pollution in the last few days.

  • India is currently under the biggest lockdown with around 130 crore people asked to stay home in view of the COVID-19 outbreak. The government has urged people to avoid unnecessary travel, significantly reducing the traffic movement across the country.

  • The level of Nitrogen Oxide (NOx) pollution, which can increase the risk of respiratory conditions, has also reduced. NOx pollution is mainly caused due to a high motor vehicle traffic.
