India should change its message for a warmer world

The issue

On 2 September the UN Environment Programme (UNEP) published Limiting Overshoot, its first report on what happens once global warming passes the 1.5°C limit of the Paris Agreement. It says the rise is set to cross 1.5°C, likely within the next few years. In the most hopeful scenario, warming peaks at 1.8°C above pre-industrial levels, and most other scenarios give higher peaks. 2024 was already the first calendar year above 1.5°C.

The report proposes an "overshoot, peak and decline" pathway: cut greenhouse gases, including methane, right away to keep the peak low, reach net zero, and then bring temperatures down with net-negative emissions and carefully governed carbon dioxide removal (CDR). It warns that CDR is no substitute for cutting emissions, and can only help if peak warming stays well below 2°C. It also says that countries with greater responsibility for climate change should act fastest. COP31, hosted by Türkiye, follows later this year.

India's commitments are net zero by 2070 and, in its updated Nationally Determined Contribution of 2022, a 45% cut in the emissions intensity of GDP from 2005 levels by 2030. India has not joined the Global Methane Pledge.

Our view

India's argument on equity still holds. Its emissions per person are far below those of rich countries, and the report itself asks the largest historical emitters to move first. India should say so at COP31.

But the report changes where India's interest lies. In an overshoot world the question is how high the peak goes, and every tenth of a degree means more heatwaves, a less reliable monsoon and more stress on crops in India. A country this exposed gains from a low peak even if others are slow. So India's message should move from what others owe to what the world must do to keep the peak down, with India doing its share.

Methane is where India can act fastest without touching the farmer. Its methane from rice and livestock is tied to small farms, which is why it stays out of the pledge. Methane from landfills, coal mines and gas pipelines is different: cutting it saves money and improves air quality. A domestic target for these sources would add weight to India's voice without joining the pledge.

The other side

• Any methane target could, over time, bring pressure on rice and livestock, which support millions of small farmers.
• The overshoot idea can be read as permission to delay, with rich countries counting on future carbon removal. Novel CDR is unproven and, UNEP notes, can cost up to US$600 a tonne.
• Adaptation finance remains small, and asking India to raise ambition without it shifts the burden to a developing country.

Using it in Mains

This fits GS Paper 3 (environment, climate change) and GS Paper 2 (India's position in international negotiations). For BPSC, use it in General Studies on environment and ecology.

Q. "In a world that has crossed 1.5°C, India's climate diplomacy must change." Critically examine this statement in the light of UNEP's Limiting Overshoot report.

• Overshoot, peak and decline, and why a lower peak matters.
• Carbon dioxide removal as a supplement, never a replacement.
• Methane from waste, coal and gas as India's fastest lever.
• Equity and common but differentiated responsibilities at COP31.
• Keywords: net-negative emissions, tipping points, adaptation finance, NDC.
