On November 21, 2025, the closing day of the 30th edition of the
Conference of the Parties (COP) took place, the yearly gathering of
United Nations member states to negotiate international climate agreements and assess global progress toward emissions reduction. This year, the event was held in
Belém,
Brazil, a port city of fewer than 1.5 million people, widely known as a gateway to Brazil's lower
Amazon region. First convened in 1992, UN
Climate Change Conferences (or COPs) are an international multilateral decision-making forum on climate change involving 198 "Parties" (197 countries, nearly all of them, depending on definitions of country, and the European Union). Their purpose is to assess global efforts toward
the central Paris Agreement aim of limiting global warming to as close as possible to 1.5 °C above pre-industrial levels. The event brings together leaders and negotiators from member states, business figures, young people, climate scientists, Indigenous Peoples, and civil society around issues considered essential to that climate goal. This year, COP30 was marked by
strong criticism of its ties to the fossil fuel industry, descriptions of agreements as fragile and insubstantial, and the struggle to move climate finance "from pledge to lifeline."
