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. Heat stress is not new to India. Over the past two decades, the country has [...]

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 [...]

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 [...]

Baku conference has shown up the glaring inadequacy of the international climate framework and the deep mistrust among nations. Bad news for the fight against climate change. Mahatma Gandhi’s famous critique of the Cripps Mission in 1942—describing its proposal as “a post-dated cheque on a crashing bank”—perfectly captures the essence [...]

COP29, being held in Baku, Azerbaijan, from Nov 11 to 22, has opened under ominous circumstances. The re-election of Trump as US president looms over the event, reviving memories of his first term when he withdrew from the Paris Agreement, halted climate funding, and significantly slowed international climate progress. During [...]

These are anxious times for the climate community, watching with bated breath to see who will become the next US president. The last time Donald Trump held office, he withdrew from the Paris Agreement and stalled efforts to curb domestic emissions. But would Kamala Harris take a radically different approach [...]

We know we’re losing the battle against air pollution, yet we persist with the same corrective measures, hoping for different results. The Graded Response Action Plan (GRAP) serves as a good example. GRAP protocols are triggered when the Air Quality Index (AQI) reaches “poor” category. However, most measures within GRAP [...]
