UNEP Emissions Gap Report 2026: 1.5°C without overshoot is lost
Illustration (AI-generated)

The United Nations Environment Programme (UNEP) released its Emissions Gap Report 2026 in Nairobi on 21 October, finding that limiting warming to 1.5°C with no or limited overshoot is no longer possible. A return to 1.5°C by 2100 needs emissions cuts of 18% by 2030 and 45% by 2035 from 2025 levels; fully delivered NDCs give only 11-15% by 2035.

Why this matters for UPSC

GS3 environment and climate change: Prelims can ask who publishes the Emissions Gap Report, what Article 4 and Article 14 of the Paris Agreement provide and India's NDC targets; Mains, about India's climate commitments and overshoot.

Why it matters

A tenth of a degree sounds small, but each one brings more of the floods, heatwaves and wildfires that already cost lives and crops. A farmer in Vidarbha or a fisher on the Odisha coast lives with the result of choices made in Washington, Beijing and Brussels. The report says the world will now pass 1.5°C before it can come back, so the real question is how high the peak goes and how many years it lasts. That depends on cutting coal and methane quickly and on pulling carbon back out of the air, which the report calls uncertain at the scale needed. For India, it means growing its economy while the room left for emissions keeps shrinking.

Prelims pointers

  • Emissions Gap Report: first issued in 2010 and released every year before the UNFCCC COP; recent editions measured gaps against IPCC AR6 pathways.
  • UNEP, founded in 1972, hosts the United Nations Environment Assembly, whose membership is universal: all 193 UN Member States.
  • Intergovernmental Panel on Climate Change (IPCC): created in 1988 by the World Meteorological Organization (WMO) and UNEP; its AR7 is the next assessment cycle.
  • Paris Agreement: adopted at COP21 on 12 December 2015, in force since 4 November 2016; 195 Parties (194 States plus the European Union).
  • Article 4 of the Paris Agreement: each Party communicates an NDC every five years, and each successive NDC must be a progression beyond the current one.
  • Article 4.4 of the Paris Agreement: developed countries lead with economy-wide absolute targets; developing countries are encouraged to move towards economy-wide targets over time.
  • Article 14 of the Paris Agreement: the first global stocktake in 2023, then every five years; its outcome informs Parties' next NDCs.
  • India's NDC 2031-35: 47% cut in emissions intensity of GDP by 2035 from 2005; about 60% non-fossil installed power capacity; carbon sink of 3.5-4.0 billion tonnes CO2e.

Practise a UPSC-style question

With reference to the Emissions Gap Report and the bodies linked to it, consider the following statements:

1. The Emissions Gap Report is published every year by the World Meteorological Organization ahead of the UNFCCC COP.

2. The United Nations Environment Programme and the World Meteorological Organization created the IPCC in 1988.

3. The United Nations Environment Assembly, hosted by UNEP, has all 193 UN Member States as its members.

Which of the statements given above is/are correct?

  1. (a) 1 and 2 only
  2. (b) 2 and 3 only
  3. (c) 1 and 3 only
  4. (d) 1, 2 and 3
Show the answer

Answer: (b) 2 and 3 only

Answer: (b) 2 and 3 only. UNEP, not the WMO, publishes the Emissions Gap Report.

Statement 1: incorrect. The Emissions Gap Report has been published every year since 2010 by UNEP, with the UNEP Copenhagen Climate Centre, before each COP.

Statement 2: correct. The IPCC was created in 1988 by the World Meteorological Organization and the United Nations Environment Programme.

Statement 3: correct. UNEP hosts the United Nations Environment Assembly, whose membership is universal: all 193 UN Member States.

Eliminate: Statement 1 credits the report to the wrong body, so every option with 1 goes. Out: (a), (c), (d).

Trap: Swapped attribution. The WMO is a real partner of UNEP in the IPCC, which makes it a believable but wrong publisher of the gap report.

Remember: Emissions Gap Report = UNEP, yearly since 2010; IPCC = WMO + UNEP, 1988.
