The COP30 climate summit is set to begin in Belem, Brazil, marking 30 years since the initial U.N. climate treaty was signed. This year's conference aims to re-focus on implementing past pledges, particularly regarding fossil fuel phase-out.

• The Conference of the Parties (COP) annually brings together countries that signed the 1992 U.N. climate treaty.
• Brazil, as the host, is emphasizing the importance of protecting the Amazon rainforest and including indigenous groups in discussions.
• The summit acknowledges the failure to meet the past goal of preventing warming above 1.5 degrees Celsius, urging action on existing commitments rather than new ones.
