IPCC AR6 Updates Global Warming Potential Values for Key Greenhouse Gases

August 2021

The IPCC Sixth Assessment Report Working Group I updated GWP values for all major greenhouse gases, with significant implications for climate policy and carbon accounting. Methane's 100-year GWP increased from 28 (AR5) to 27-30 (AR6), while incorporating climate-carbon feedbacks raised it to 82-84 for the 20-year horizon. These updates affect how countries calculate their emission inventories and NDCs under the Paris Agreement.

UPSC Angle: UPSC likely to test updated GWP values, their policy implications for India's climate commitments, and the scientific basis for these revisions. Questions may focus on how changing GWP values affect international climate negotiations and carbon market mechanisms.

Global Methane Pledge Launched at COP26 with 100+ Country Commitments

November 2021

The Global Methane Pledge, co-led by the US and EU, commits signatory countries to reduce methane emissions by 30% by 2030. This initiative directly leverages GWP science, particularly methane's high 20-year GWP of 82-84, to argue for immediate climate benefits. India initially did not join but has since indicated interest, making this a key current affairs topic linking GWP science to policy action.

UPSC Angle: Expected questions on why methane reduction is prioritized (high GWP), India's position on the pledge, and how GWP calculations influence international climate initiatives. May appear in both Prelims (factual) and Mains (analytical) formats.
