COP Conferences
How the annual Conference of the Parties works and the key breakthroughs and failures in its history.
Inside the COP
The Conference of the Parties (COP) meets annually and is the supreme decision-making body of the UNFCCC. Each COP brings together negotiators, heads of state, civil society, businesses, and activists. Attendance has grown from hundreds to over 70,000.
Decisions require consensus — any single country can block agreement. This gives enormous leverage to both major emitters and vulnerable nations. Negotiations typically run into overtime, with final texts agreed at 3 AM after marathon sessions.
Key COPs:
- COP3 (Kyoto, 1997) — Kyoto Protocol adopted
- COP15 (Copenhagen, 2009) — Failed to produce a binding agreement
- COP21 (Paris, 2015) — Paris Agreement adopted
- COP26 (Glasgow, 2021) — Glasgow Climate Pact; first mention of fossil fuel 'phase down'
- COP27 (Sharm el-Sheikh, 2022) — Loss and damage fund established
- COP28 (Dubai, 2023) — First Global Stocktake; agreement to 'transition away from fossil fuels'
The phrase 'transition away from fossil fuels' at COP28 was historic — the first time any COP text explicitly named fossil fuels as the problem, 28 years after the UNFCCC was adopted.
