For more than a decade, Delhi has experimented with various pollution control measures — the ‘odd-even scheme’, smog towers, water cannon, tree plantation, the Graded Response Action Plan or GRAP, (which restricts industry, construction, and vehicular activity during winter), and now cloud seeding. Despite these efforts, the city continues to [...]

The world needs a new multilateral architecture for a new phase of climate action. Brazilian President Luiz Inácio Lula da Silva had declared the 30th Conference of Parties (COP30) to the UN Framework Convention on Climate Change (UNFCCC) as the “COP of truth”. And truth, indeed, was unmistakable in Belém. [...]

Experiments around the world have already established that cloud seeding can’t defeat air pollution. What Delhi is doing in their wake can’t even be called innovation. It’s just political theatre Yesterday, to mitigate air pollution, Delhi govt, in collaboration with IIT Kanpur, conducted the first cloud-seeding trial in areas like [...]

World Ozone Day is a good reminder of what refrigerants used in millions of air-conditioners do to environment. Hydrofluorocarbons heat up earth even more than CO2. The ozone hole is healing. The layer that shields us from the sun’s deadly ultraviolet rays was severely damaged by chemicals like chlorofluorocarbons (CFCs) [...]

On September 2, 2025, Bhubaneswar became the first Indian city to release an Integrated Heat and Cooling Action Plan (IHCAP) to comprehensively tackle two growing crises—rising heat stress and the explosion in air conditioning demand.

Spanning the coal-rich districts of Jharkhand and West Bengal, Damodar Valley (DV)—India’s ‘Ruhr Valley’—has powered the country’s growth since Independence. Coal from Jharia and Raniganj has fuelled India’s rise while steel plants of Durgapur and Bokaro, and fertiliser factories of Sindri became ‘temples of modern India’. Today, the region stands [...]

Public backlash has forced Delhi govt to walk back from its initiative to impound ‘end of life’ vehicles. But before this, the sudden outrage over the directive to stop refuelling diesel vehicles older than 10 years and petrol vehicles older than 15 years was somewhat amusing. Many seemed to believe [...]

AC temperature cap, while not a game-changer, opens the door to much-needed conversations on an urgent developmental need. The Indian government is reportedly contemplating to limit air conditioner (AC) temperature settings between 20°C and 28°C. This seem like a minor technical move, but it marks an important symbolic step in [...]

Heat Action Plans across cities will fail because they are not backed by money & they don’t factor in local conditions. Heatwaves must be classified as natural disasters, with legally binding solutions. The heatwave of 2024 had a devastating impact in most parts of the country. While we will never [...]

IT is 6.30 in the morning and you are starting your day in Gurugram. A thin fog, more like a mist, hangs low outside. You check your phone for the weather report to see if there could be rain coming. Along with the weather, you check the Air Quality Index [...]

Given the powerful sway of faith, it must work together with science and technology to repair humanity’s broken relationship with nature. The Mahakumbh Mela 2025 has left an indelible mark on history. According to official data, more than 650 million people participated in this monumental event — equivalent to the [...]
