COP27 is the 27th Conference of the Parties (countries) that signed up to the United Nations Framework Convention on Climate Change. The convention was established at the Rio Earth Summit in 1992, and has been ratified by 198 countries. They agreed to stabilise the production of greenhouse gases in order to prevent dangerous climate change.
Since then, the Conference of the Parties has been hosted in a different country each year. These conferences broadly provide a platform for the negotiation of international climate change treaties.
