Paris Agreement
"The landmark 2015 international climate accord under UNFCCC committing nations to limit global warming to well below 2 degrees Celsius above pre-industrial levels, with efforts to limit it to 1.5 degrees Celsius."
The Paris Agreement is a legally binding international treaty on climate change, adopted at the 21st Conference of the Parties (COP21) to the UNFCCC (United Nations Framework Convention on Climate Change) in Paris on December 12, 2015, and entered into force on November 4, 2016. It replaced the Kyoto Protocol (1997), which had binding emission reduction targets only for developed countries (Annex I). The Paris Agreement's central goals are: to limit global average temperature increase to well below 2°C above pre-industrial levels, with efforts to limit it to 1.5°C; to strengthen countries' ability to adapt to climate impacts; and to align financial flows with low-carbon, climate-resilient development. Unlike Kyoto, Paris applies to all countries (developed and developing) through a bottom-up system of Nationally Determined Contributions (NDCs) — each country sets its own targets and updates them every five years with progressively higher ambition (ratchet mechanism). India's NDCs (updated 2022): achieve 45% reduction in emissions intensity of GDP by 2030 from 2005 levels (revised from 33-35%); achieve 50% cumulative electric power installed capacity from non-fossil fuel-based energy by 2030 (revised from 40%); achieve net zero emissions by 2070. India also announced the LiFE (Lifestyle for Environment) initiative and the Panchamrit (five elements of India's climate commitments) at COP26 (Glasgow, 2021). Key mechanisms: Loss and Damage (Article 8, COP27 Sharm el-Sheikh 2022 — a separate fund established); Climate Finance (developed nations committed USD 100 billion/year — not yet consistently met); Carbon markets (Article 6). US withdrew under Trump (2017) and rejoined under Biden (2021).
Critical for UPSC GS3 Environment (climate change), GS2 International Relations (multilateral diplomacy), and Essay. Key facts: COP21 Paris, December 2015; 196 parties; entered force November 2016; 1.5°C / 2°C target; India's NDCs; net zero 2070; Loss and Damage fund (COP27). Distinguish: UNFCCC (parent treaty, 1992 Rio Earth Summit) → Kyoto Protocol (1997, binding for Annex I) → Paris Agreement (2015, all countries, voluntary NDCs). IPCC reports (especially AR6, 2021-22) are the scientific basis for Paris Agreement negotiations.
- 1 Adopted COP21, Paris, December 12, 2015; entered force November 4, 2016
- 2 Target: well below 2°C warming; efforts to limit 1.5°C above pre-industrial levels
- 3 NDCs (Nationally Determined Contributions): country-set targets, updated every 5 years (ratchet)
- 4 India NDC (updated 2022): 45% emissions intensity reduction by 2030; 50% non-fossil electricity by 2030; net zero by 2070
- 5 India's Panchamrit (COP26 Glasgow 2021): 5 elements of climate commitment
- 6 Loss and Damage Fund: established at COP27, Sharm el-Sheikh (2022)
- 7 Climate Finance: USD 100 billion/year pledge by developed nations — not consistently met
- 8 US: withdrew under Trump (2017); rejoined under Biden (2021); withdrawal again under Trump 2.0 (2025)
India's commitment to achieve 500 GW of non-fossil electricity capacity by 2030 under its updated NDC requires massive investment in solar, wind, and green hydrogen — the International Solar Alliance, launched by India and France on the sidelines of COP21 in 2015, is a direct multilateral initiative emerging from the Paris Agreement process.
