Nationally Determined Contribution
"Climate action plans submitted by each country under the Paris Agreement, updated every five years with progressively higher ambition"
A Nationally Determined Contribution (NDC) is the climate action plan that each party to the Paris Agreement (2015) is required to submit to the UNFCCC. NDCs outline the country's commitments on greenhouse gas emissions reduction, adaptation measures, and means of implementation. Under Article 4 of the Paris Agreement, each successive NDC must represent a progression beyond the previous one (the 'ratchet mechanism'). NDCs are reviewed through a Global Stocktake every five years. India submitted NDC 1.0 at COP21 (2015), updated it as NDC 2.0 in August 2022 (translating the Panchamrit goals), and approved NDC 3.0 in March 2026 with targets of 47% emissions intensity reduction, 60% non-fossil power capacity, and 3.5-4.0 billion tonnes CO2 equivalent carbon sink by 2035.
NDC is one of the most important environment and IR terms for UPSC. It connects the Paris Agreement architecture, UNFCCC process, India's climate diplomacy, renewable energy targets, and the CBDR-RC principle. NDC 3.0 targets are highly likely Prelims questions for 2026-27 exams.
- 1 Mandated under Article 4 of the Paris Agreement (adopted December 2015, COP21)
- 2 Each party must submit progressively ambitious NDCs every five years
- 3 India NDC 1.0 (2015) set 33-35% emissions intensity cut and 40% non-fossil capacity by 2030
- 4 India NDC 2.0 (August 2022) raised targets to 45% intensity cut and 50% non-fossil capacity
- 5 India NDC 3.0 (March 2026) targets 47% intensity cut, 60% non-fossil capacity, and 3.5-4.0 BT CO2e carbon sink by 2035
- 6 India achieved 52.57% non-fossil capacity by February 2026 — surpassing NDC 2.0 five years early
- 7 Net-zero target remains 2070
India's NDC 3.0, approved by the Union Cabinet on 25 March 2026, commits to 60% of installed power from non-fossil sources by 2035 — building on the early achievement of the 50% NDC 2.0 target.
