By Lisandra Paraguassu As world leaders grapple with the U.S. withdrawal from the Paris Agreement, Brazil, the host of this year’s COP30 global climate summit, sees an opportunity to amplify the voices of developing nations in what will be a fierce dispute over who will pay for the global transition to cleaner energy sources.

Brazil warned Tuesday that US President Donald Trump's decision to withdraw from the Paris climate agreement would have a major impact on COP30 talks to be held in the Amazon in November.

President Luiz Inacio Lula da Silva has decided to name Andre Correa do Lago, the secretary of energy and environment at Brazil’s foreign affairs ministry, as head of the annual United Nations Climate Change Conference the country will host later this year.

Brazil's newly nominated head of the planned 2025 COP30 climate summit in the Amazonian city of Belem warned on Tuesday that President Donald Trump's decision to withdraw the United States from the Paris Agreement would cast a shadow over the talks.

With Trump withdrawing the US from the Paris Accord, COP30 in Brazil's Amazon faces heightened challenges and global stakes.

The US withdrawal from the Paris climate accord for a second time under President Donald Trump will have a “huge impact” on efforts to curb global warming, the incoming head of the UN COP30 climate summit has warned.

Brazil sees an opportunity to amplify the voices of developing nations in upcoming climate finance talks, according to comments on Thursday from the head of the global COP30 summit set to be hosted by the South American nation later this year.

The US reversal on climate change will have “a big influence” on discussions at the global summit, said COP30 President Andre Correa do Lago.
