Andre Correa do Lago, the president of COP30, has acknowledged the difficulties Brazil will encounter as the host in light of these changes in US climate policy.

Correa do Lago also stressed the importance of understanding how other nations will react to the US's shift in climate strategy, as this will likely influence the discussions at the summit.

Brazil is preparing to host COP30, the climate summit, against a backdrop of rising global temperatures, having already reached the critical threshold of 1.5°C of warming in 2024.

This summit will be particularly challenging due to the complexities introduced by President Donald Trump's withdrawal of the United States from the Paris Agreement, which has significantly affected global climate negotiations.
