Delhi witnessed a severe episode of smog in the first week of November, which was described the Centre for Science and Environment (CSE) as the worst in 17 years.
Since then, the local and the Central authorities announced a number of steps including the closure of the Badarpur thermal power plant and a temporary ban on construction and demolition activities.
The Centre has also notified the Graded Response Action Plan and empowered the Supreme Court-appointed panel Environment Pollution (Prevention and Control) Authority to implement it.
