A landmark study and a sweeping legal move have thrust India’s air-quality crisis into the spotlight, urging policymakers and courts alike to treat polluted air not just as an environmental issue but a full-blown public health emergency.

The cost of Tuesday’s two flights alone is estimated at ₹1.2 crore (approximately) as part of the pilot. While rainfall did not materialise, IIT Kanpur reported modest reductions in particulate matter (PM₂.₅ and PM₁₀) at test locations, roughly 6 to 10 per cent lower concentrations.

Delhi Chief Minister Rekha Gupta told reporters she was confident the state was “fully geared to fight pollution,” referencing the Centre’s approval of the cloud seeding plan.

Delhi Environment Minister Manjinder Singh Sirsa has ordered a time-bound scientific study of photocatalytic “smog-eating” coatings, including titanium dioxide-based surfaces, hoping they may offer a drawbridge between policy and technological innovation to reduce harmful pollutants like nitrogen dioxide (NO₂) and volatile hydrocarbons.

Dhaka is warming faster than the rest of the country, and the consequences for public health, productivity, and well-being are growing.
