On September 24, 2025, Brazilian President Luiz Inácio Lula da Silva addressed the UN Climate Summit in New York, calling for global action to uphold the Paris Agreement and reject climate denialism. Lula stressed that all nations must submit and honor their Nationally Determined Contributions (NDCs), describing them as essential roadmaps for achieving emissions reductions. He warned against the dangers of unilateralism, emphasizing that no borders, weapons, or power can shield countries from the impacts of droughts, storms, and rising temperatures.
Lula also highlighted Brazil’s leadership, noting it was the second country to submit its updated NDC, with a central pledge to end Amazon deforestation by 2030. His speech contrasted sharply with US President Donald Trump’s address a day earlier, in which Trump dismissed climate change as a hoax. Lula cautioned that failing to act would not only worsen global warming but also erode trust in democratic institutions and multilateralism, ultimately empowering climate denialism worldwide.
