The Commission for Air Quality Management (CAQM) has not conducted any scientific study or pollution research regarding the environmental impact of 10-year-old diesel and 15-year-old petrol vehicles, prior to imposing restrictions on their usage, a Right To Information (RTI) response to a query filed by an individual, Amit Gupta, has revealed.
The ban on older vehicles-a matter that has directly impacted thousands of vehicle owners in Delhi-NCR-was imposed, the CAQM clarified, was not an independent one, but a compliance measure based on prior judicial directions issued by the National Green Tribunal (NGT) in Vardhman Kaushik Vs. Union of India & Or, and the Supreme Court order in M.C. Mehta Vs. Union of India & Ors.
The RTI reply also includes a reference to a letter dated July 3, 2025, received from the Government of NCT, Delhi, which appears to have been enclosed as part of the information provided to the applicant.
Citizens unsatisfied with the RTI response have been advised to file an appeal within 30 days with the First Appellate Authority, the Director at CAQM.
With no scientific research conducted or cited, the response dated July 28, 2025, raises questions regarding the evidence base for the decision to ban vehicles purely based on age. Environment activists have earlier pointed out that emissions depend on maintenance and usage patterns rather than age alone. For now, the Commission has disposed of the RTI request, making it clear that the policy is rooted in judicial compliance rather than fresh empirical research. The lack of empirical backing raises concerns over the effectiveness of blanket bans.
The average daily microplastic exposure rose from 10.7 particles in the colder months to 21.1 in the hotter season, the study highlighted.
Monsoon ushers in respiratory trouble for many and pneumonia cases rise sharply, driven by damp air, viral spread, indoor pollutants, and rain-wetting. Children, elderly, and those with compromised immunity are most vulnerable.
Rain lashed several parts of Delhi and the surrounding National Capital Region (NCR) on Saturday evening. Areas including Lajpat Nagar, RK Puram, Lodhi Road, and Mandir Marg witnessed light showers.
In a bid to tackle one of the worst sources of air pollution, Delhi has begun testing retrofitting devices that promise to cut harmful emissions from heavy commercial vehicles by more than 70 per cent.
Delhi is gearing up to build one of India's most advanced e-waste processing facilities, and it's taking cues from Norway's cutting-edge model.

Friday December 20, 2024While some may argue that people in Delhi are now more aware of air pollution than they were a decade back, my rebuttal would be that awareness does not mean that people are concerned.

Friday November 22, 2024On a good day, such as today, the AQI reading in Delhi is 407. We are jubilant at the sickly sunshine trickling through the slightly dissipated smog. At least its not 1600.

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
