**In one line:** UNEP's 2026 Emissions Gap Report says the world can no longer avoid crossing 1.5°C, and asks for steep cuts so that warming peaks at 1.7 to 1.8°C and then falls back.

The UN Environment Programme (UNEP) released its Emissions Gap Report 2026, titled 'The Point of Return', on 21 October 2026. The annual report says that crossing the 1.5°C warming limit of the Paris Agreement can no longer be avoided. UNEP Executive Director Inger Andersen said the chance of holding warming below 1.5°C 'with no or limited overshoot is gone'. The report now lays out the 'lowest possible' overshoot path, in which warming peaks at 1.7 to 1.8°C around mid-century and returns below 1.5°C by the end of the century.

That path needs global greenhouse gas emissions to fall 18% below 2025 levels by 2030, 45% by 2035 and 69% by 2040, along with removal and permanent storage of about 320 billion tonnes of carbon dioxide this century. By 2035 the shares of coal, oil and gas in total energy supply would have to fall by at least 55%, 15% and 5%. Against this, current policies point to 2.8°C of warming this century, full delivery of national pledges (Nationally Determined Contributions or NDCs) to 2.6°C, and pledges plus net-zero targets to 2.1°C. NDCs would cut emissions by only 5 to 8% by 2030 and 11 to 15% by 2035. Every five years of emissions at current levels adds about 0.1°C to peak warming.

Global emissions in 2025 were roughly flat compared with 2024. The United States recorded the largest increase of any country, about 133 million tonnes of CO2 equivalent; it has withdrawn from the Paris Agreement and its State Department said it did not endorse the report's conclusions. The G20 accounts for about three-quarters of global emissions. On the positive side, global renewable electricity capacity has grown three times faster since Paris than was anticipated, and solar power seven times faster. The report comes before COP31, due in Antalya, Türkiye, in November, where countries will face pressure to raise ambition. For India, the findings sharpen the equity debate: deep global cuts are needed, but historical responsibility and finance remain central.

## Prelims practice question

With reference to the UNEP Emissions Gap Report 2026, consider the following statements:
1. It says global emissions must fall 18% below 2025 levels by 2030 on the lowest-overshoot pathway.
2. It projects that full delivery of current NDCs would hold warming below 2°C this century.
3. Its lowest-overshoot pathway returns warming below 1.5°C by the end of the century.
Which of the statements given above are correct?

(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3

Answer: (b) 1 and 3 only. Statement 1 is correct: 18% by 2030, 45% by 2035, 69% by 2040. Statement 2 is wrong: full NDC delivery leads to about 2.6°C. Statement 3 is correct: the path peaks at 1.7 to 1.8°C and returns below 1.5°C by 2100.

## Mains practice question

The Emissions Gap Report 2026 concedes that crossing 1.5°C is now unavoidable. Explain the idea of a temperature 'overshoot' and discuss what it means for global climate action and for India's negotiating position. (250 words)

### Model answer

UNEP's Emissions Gap Report 2026 ('The Point of Return') states that warming will cross 1.5°C, shifting the goal to limiting the peak and returning below 1.5°C by 2100.

## What overshoot means
- Temporary breach of a limit, then reversal through net-negative emissions.
- Lowest path: peak of 1.7 to 1.8°C around mid-century, return below 1.5°C by 2100.
- Needs about 320 billion tonnes of CO2 removal this century.

## Implications for global action
- Cuts of 18% by 2030, 45% by 2035 and 69% by 2040 below 2025 levels; NDCs give only 5 to 8% by 2030.
- Current policies lead to 2.8°C; full NDCs to 2.6°C.
- Each five years of delay adds about 0.1°C to the peak, so near-term action matters most.
- Reliance on unproven removal at scale risks becoming an excuse to delay.

## India's position
- Equity and common but differentiated responsibilities: the G20 emits about three-quarters of the total, and the US had the largest rise in 2025 while leaving the Paris Agreement.
- Demand finance and technology transfer at COP31 in Antalya.
- Use the report's finding that renewables grew three times faster than expected since Paris (solar seven times) to frame clean energy as a growth opportunity.
- Keep domestic action credible to retain moral authority with vulnerable nations.

## Way forward
- Stronger NDCs in the next round, phased reduction of coal, oil and gas shares, and investment in natural carbon sinks.

Overshoot is a warning, not a new comfort zone: the lower the peak, the smaller the irreversible damage.

## The basics

## Why this matters

For a decade, 1.5°C was the line the world said it would not cross. The Emissions Gap Report 2026, titled 'The Point of Return', from the UN Environment Programme (UNEP), says plainly that warming will pass 1.5°C. The question has changed from 'how do we stay below?' to 'how high do we peak, and how fast can we come back down?' Prelims asks about the Paris Agreement temperature goal and Nationally Determined Contributions (NDCs); Mains asks what this means for India's climate diplomacy.

## What an 'emissions gap' is

The gap is the difference between where emissions are heading under countries' pledges and where they need to be to meet the Paris goals. UNEP has published this assessment every year since 2010, ahead of each UN climate conference (UNEP and the Emissions Gap Report).

## What 'overshoot' means

In an overshoot, temperature rises above a limit for some decades and is then brought back down. Bringing it back needs net-negative emissions: removing more carbon dioxide than is emitted. The report's lowest-overshoot path needs about 320 billion tonnes of CO2 removed and stored this century.

## The cuts the report asks for

Current NDCs would cut emissions by only 5 to 8% by 2030 and 11 to 15% by 2035. Each five years of emissions at current levels adds about 0.1°C to peak warming.

## The India angle

India argues for equity and 'common but differentiated responsibilities'. The report also shows that renewable electricity capacity has grown three times faster since Paris than was expected, and solar seven times faster, which strengthens the case for clean energy as growth strategy rather than a cost.
