Overview
- At preparatory forums in Rio, the C40 mayors’ summit and a global states-and-regions gathering are aligning local priorities for delivery to negotiators in Belém.
 - A C40 report finds 60 member cities have passed peak emissions, with 11 achieving cuts above 30%, evidence the network says demonstrates scalable urban decarbonization.
 - COP30 president André Corrêa do Lago says adaptation is the conference’s absolute priority, as Brazil pursues a US$10 billion public funding target for a Tropical Forests Fund.
 - The White House signaled President Donald Trump will not attend, while the U.S. Climate Alliance reported a 24% emissions drop since 2005 and reaffirmed state‑level climate action.
 - Brazil’s federal government decreed a Garantia da Lei e da Ordem in Pará ahead of the summit, adding a security layer as COP30 convenes in Belém from November 10 to 21.
