We know the city is eight years old.
5 million cars
Delhi adds 1,400 new cars to crowded streets every day

What's more difficult is
Fight against air pollution.
Last year, we even made a report on why Delhi lost the clean air war.

By the way, we also know what needs to be done in Delhi to clean the air.
The city needs to expand public transport, clean up congestion around the subway station and improve the last mile connection between the station and the community.

Other parts of India-
Serious implementation of a comprehensive clean air law dating back to 1981 was needed, but was hampered by poor implementation.

Successive governments have been reluctant to cut subsidies that ultimately benefit the rich.
