Combating air pollution in Delhi

The Delhi government has deployed truck-mounted water sprinklers to combat the effects of air pollution. Additionally, the Supreme Court has directed stricter enforcement of restrictions under stage IV of the Graded Response Action Plan (Grap), which includes prohibiting truck entry into Delhi, restricting movement of certain diesel vehicles within the city, and banning public construction projects.

 

On Friday, the Supreme Court said that Grap Stage IV measures could be removed after three days. The apex court also appointed 13 Bar members as court commissioners to monitor compliance at the 113 entry points into the city.

 

Meanwhile, Delhi Environment Minister Gopal Rai has instructed strict adherence to Grap measures and called for coordinated action under the Winter Action Plan 2024. Departments are required to submit daily progress reports, and enforcement mechanisms have been strengthened to penalise violators of pollution norms. 

What is Delhi's  Winter Action Plan 2024?

Delhi’s Winter Action Plan 2024 outlines a 21-point strategy to combat air pollution during the colder months. Measures include drone monitoring of 13 pollution hotspots, intensified anti-dust campaigns, deployment of water sprinklers and smog guns, and stricter vehicular and industrial pollution controls.
