In 2015, when AAP came to power, this was the situation on Environment in Delhi:

  • In the winter of 2015, Delhi had become a gas chamber with dangerously high PM 2.5 levels.
  • The city was on the verge of an environmental crisis.
  • Government agencies were refusing to take responsibility for the problem and were passing the blame around.

Now, in 2021, after AAP:

  • A 25% reduction in the 3-year average of PM2.5 levels (between 2012-2014 and 2016-2018)
  • A 25% reduction in overall particulate pollution
  • Pollution peaks getting lower
  • Number of severely polluted days a year has reduced from 20-40 to less than 15
  • More low-pollution days during summer and monsoon months
