Double, Double Toil and Trouble

India’s Midsummer Reckoning with Climate

--

On 27 April 2026, something happened that should have rattled every boardroom in Mumbai and every desk in North Block. Every single one of the planet’s top 50 hottest cities was in one country: India. Average peak temperatures across those 50 cities hit 112.5°F. Banda, in Uttar Pradesh, touched 115.16°F — the hottest spot on Earth that day. The air-quality platform that compiled the data put it plainly: “no modern precedent.”

This is not a weather story. It is a balance-sheet story.

We like to tell ourselves a triumphalist tale: India is the fastest-growing major economy in the world, and economic development is both the means and the moral cover. Absolute emissions? Yes, large — India contributes around 8% of global energy-sector CO₂ despite housing 18% of the world’s people. So we point to per capita: roughly 2.6 tonnes per Indian against a global average of 6.3. The denominator does the apologetics for us.

But the atmosphere does not divide by population. It integrates by tonne. And the heat that bakes Banda does not pause to check whether each Indian is consuming a fair share.

The coal trilemma — two out of three

The energy trilemma — security, affordability, sustainability — has always been a “pick two” problem for India, and we have been picking the first two. Coal still generates close to 69% of India’s electricity in 2025. It is cheap, domestic, and underwrites the grid that keeps factories, hospitals and — increasingly — the 1.4 billion air-conditioners we are about to add. Non-fossil capacity has crossed 249 GW, with solar leading at 93 GW. Real progress. But coal’s absolute footprint continues to expand even as its share shrinks.

This is the genuine bind. You cannot ask 1.4 billion people, half of whom are still climbing the energy ladder, to underwrite a sustainability bill that the developed world ran up over two centuries. The witches in Macbeth did not invent the cauldron; they only stirred it. But Banquo, who walked past them with Macbeth, ended up dead all the same.

A 25% haircut on Viksit Bharat

Here is the part that should focus the mind of every CFO, every PE general partner, every infrastructure lender and every citizen.  The Asian Development Bank projects that, under a high-end emissions scenario, India could suffer a 24.7% GDP loss by 2070. Even on milder pathways, India stands to lose 5.21% of GDP by 2050, rising to 9.9% by 2100. Whichever number you favour, the climate discount on our Viksit Bharat 2047 projection is not a rounding error. It is a 20–25% haircut waiting to be applied, with compounding interest.

The insidious impacts are already visible. Researchers have warned that heat in India is becoming so extreme it may cross the survivability limit for healthy humans by 2050. Outdoor workers — construction, agriculture, logistics, the entire informal economy — lose hours. Children lose school days. Hospitals lose surge capacity. El Niño is expected to weaken the 2026 monsoon, threatening farming, reservoirs and aquifers. And on top of all this, the Iran war has cut oil supplies, leaving India short on fuel at precisely the moment cooling needs are soaring. Energy security and climate vulnerability are no longer separate ledgers. They are the same ledger, double-entry.

From CSR footnote to P&L item

If climate risk is a 20–25% drag on the national P&L, it deserves the same governance machinery as any other systemic risk. We have built that machinery before — for credit risk, for operational risk, for market risk. We can build it for this. Four things would change the conversation:

First, climate stress testing of the financial system. The RBI has begun the work; it now needs teeth. Every bank and NBFC of consequence should run physical-risk scenarios that include heat-stress productivity loss in its corporate book, not just transition-risk scenarios on fossil exposure.

Second, real BRSR teeth, not box-ticking. SEBI’s Business Responsibility and Sustainability Report should move from disclosure ornament to capital-allocation instrument. Investors do not need 1,000-row spreadsheets; they need three numbers they can trust: Scope 1, Scope 2, and a credible Scope 3 estimate, audited.

Third, just-transition planning for the coal belt. Jharkhand, Chhattisgarh, Odisha and Telangana cannot be left to discover the energy transition as a redundancy notice. NITI Aayog has the convening authority. State-level transition compacts — with reskilling, land redeployment and stranded-asset financing — need to be funded, not just announced.

Fourth, design for 50°C, not 40°C. Every new road, every new factory floor, every new affordable-housing block underwritten by HUDCO or NHB should be specified to a climate envelope that assumes the heat index hits 122°F before lunch. The marginal cost is small. The retrofit cost, ten years from now, will not be.

Toil and trouble

“Double, double toil and trouble; fire burn and cauldron bubble.” Shakespeare’s witches were a warning that what is brewed in the dark eventually finds its way to the king’s door. Our cauldron has been bubbling for thirty years. April’s heat-and-light show is the lid coming off.

This does not mean abandoning the growth story. It means pricing it honestly. It means treating climate not as an ESG slide but as a line item on the boardroom risk register. It means PE diligence that prices heat-stress productivity loss into the operating model. It means infrastructure designed for 50°C. It means the just transition out of coal as the industrial-policy question of the next decade, not the last item on the agenda.

If we keep telling ourselves the per-capita story while the absolute story bakes our cities, then the next 21 years of growth — the whole arc from here to 2047 — will not be Viksit Bharat at all.

It will be, in the words of the other Bard, A Midsummer Night’s Dream. Beautiful, intricate, fantastical. And, when the morning comes, gone.
