A UNEP report says deep emission cuts could return global warming to 1.5°C by 2100 after a temporary overshoot.
It outlines cuts of 18 per cent by 2030, 45 per cent by 2035 and 69 per cent by 2040 from 2025 levels.
The 1.5°C aspiration comes from the Paris Agreement of 2015.

How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- The Paris Agreement (2015) aims to hold the rise in global average temperature well below 2°C and pursue efforts to limit it to 1.5°C above pre-industrial levels.
- Under the Paris Agreement, countries submit Nationally Determined Contributions (NDCs), which are updated every five years.
- The Kyoto Protocol set binding emission targets for developed countries, while the Montreal Protocol deals with ozone-depleting substances.
- UNEP is the UN body that publishes the annual Emissions Gap Report.
ಮೇನ್ಸ್
GS-III (Environment) and GS-II (International Relations). The issue is that the world is likely to overshoot 1.5°C, so the Paris goal now depends on steep cuts followed by a return to 1.5°C by 2100. The Paris framework relies on NDCs and the principle of common but differentiated responsibilities, which puts the burden of cuts and climate finance on developed countries. India should push for climate finance, technology transfer and equity in the carbon budget while speeding up its renewable energy transition.
