The Climate Coalition is the main Brazilian proposal for the United Nations Climate Conference 2025, COP30. [1] [2]
It is supported by a group of academics around MIT. The MIT group's report proposes a carbon price floor of US$50 per tonne of CO2 equivalent for all Climate Coalition members, with border carbon adjustment. [3]
The Climate Coalition would work similar to the G7 proposal of a Climate club. The proposal is distinct from the Brazilian proposal to launch a UNFCCC / World Trade Organization forum on climate and trade. [4]
