Government Response

  • The Delhi government ordered closure of all schools until Sunday.
  • The Delhi government is considering implementing the Graded Response Action Plan, a set of emergency measures meant to bring down the levels of pollution. Three key steps that could be brought in are: putting freeze on all construction activity in the Delhi-NCR region; activating an odd-even vehicle rationing system and banning entry of all trucks into Delhi.
  • Delhi is considering temporarily shutting down the local Badarpur Thermal Power Plant, brick kilns and other industrial units in Delhi NCR.
  • Union Minister for Environment, Forests and Climate Change, Dr Harsh Vardhan, who is currently in Bonn, urged the Delhi government to explore the possibility of aerial sprinting of water to bring down levels of pollution

As the landmark Lancet Study highlights air pollution is the greatest contributor for pollution-related deaths globally. The study finds that globally pollution for multiple sources contributes to nearly 9 million deaths every year—about 16% of deaths worldwide. Delhi and cities across India are experiencing alarming air pollution levels. Stronger action is clearly needed now.
