Delhi has enforced tighter rules to control air pollution after the air quality index, or AQI, reached the 'severe' category. All non-essential construction and demolition work are banned, among other actions.
The Commission for Air Quality Management (CAQM) took the decision to raise the pollution mitigation level to GRAP-3, effective from 8 am on Friday.
While GRAP-3 is in effect, petrol vehicles from the older emission norms BS-III and diesel vehicles of BS-IV category are not allowed on the roads in Delhi and parts of the National Capital Region (NCR) such as Gurugram, Ghaziabad, Faridabad, and Gautam Budh Nagar.
