Overview
- UN climate chief Simon Stiell opened the summit urging countries to act "much, much faster" and to move from complaint to solutions.
- He credited the Paris Agreement with slowing emissions growth and said solar and wind are now the cheapest power in much of the world.
- Brazil’s President Luiz Inácio Lula da Silva cast COP30 as a "conference of truth" and called for defeating climate denial and disinformation.
- André Corrêa do Lago was elected COP30 president and pressed for a science-led "COP of implementation" rooted in multilateral cooperation.
- Scientists warned current plans would cut emissions only about 5% by 2030 versus the 40–45% needed, as talks take up finance for developing countries, protection of tropical forests, and Germany raised concern about being forced to host COP31 in Bonn if no other venue is agreed.
