Centre revises air pollution control plan for Delhi-NCR, tightens curbs

The Centre's panel on Delhi-NCR air quality has issued a revised plan to tackle winter pollution, asking states to implement stricter measures when the air quality deteriorates and making it mandatory for schools to shift to hybrid learning on days with severe air pollution. Poor air quality, driven by unfavourable weather conditions, usually persists for long periods during winter, from November to January. During this time, Delhi frequently enforces restrictions under the Graded Response Action Plan (GRAP), which categorises air quality into four stages: Stage I (Poor) with AQI between 201 and 300, Stage II (Very Poor) between 301 and 400, Stage III (Severe) between 401 and 450, and Stage IV (Severe Plus) for AQI above 450. According to the revised plan, inter-state buses from NCR states, except those EVs and those running CNG or BS-VI diesel, will not be allowed to enter Delhi under Stage II. This provision earlier came into effect under Stage III. Resident welfare associations

Drone mist-spraying pilot project in hitch for high costs, limited results

A pilot project that involves the use of drones to spray mist at pollution hotspots has not been approved over the high cost and lack of measurable results, an official has said. The technology was proposed as part of Delhi's 21-point Winter Action Plan to combat worsening air quality. Officials have deemed the project costly and ineffective, stating it has failed to deliver significant, measurable improvements. "The technology is extremely expensive and does not provide noticeable advancements compared to existing methods, which are already yielding better results at a fraction of the cost," an official involved in the evaluation told PTI. On November 8, a demonstration of the project was conducted at Anand Vihar, one of Delhi's most polluted areas. During the demonstration, Delhi Environment Minister Gopal Rai highlighted challenges posed by hotspots, such as narrow roads or congested areas where traditional modes of transport, such as trucks, cannot reach.
