The UN climate summit (COP30) held in Belém, Brazil has ended, resulting in a disappointing outcome for many nations and advocacy groups fighting for urgent climate action. Amid heated debates, the final deal, dubbed the Mutirão, failed to include any direct references to fossil fuels, which scientific consensus deems crucial to curbing global warming.

Over 80 countries, including members of the EU and the UK, advocated for a commitment to rapidly decrease reliance on oil, coal, and gas, but their proposals were met with staunch resistance from oil-producing nations who argue for their right to use fossil fuel resources for economic growth.

The absence of concrete promises on fossil fuel reductions comes at a worrying time when the UN warns that global temperature goals to limit the rise to 1.5°C may not be achievable if fossil fuel consumption continues its current trajectory.

A notable moment of contention emerged from Colombia, where President Gustavo Petro criticized the COP presidency for not allowing objections to the deal during the closing plenary, stating he could not accept the agreement.

While the final deal calls for countries to voluntarily accelerate climate action, some nations expressed relief that the talks did not collapse or revert previous climate agreements. However, many voiced disappointment in the monetary support promised to help poorer countries adapt to climate change impacts. Antigua and Barbuda's Climate Ambassador Ruleta Thomas characterized the outcome as a "disappointment," yet acknowledged the importance of maintaining a dialogue where every nation could express its views.

The summit was marked by chaotic events, with heavy rains flooding the venue and protests from indigenous groups against oil drilling in the Amazon. Brazilian President Luiz Inácio Lula da Silva's focus was to spotlight the environmental richness of the Amazon, but his country faced critique for planning new oil drilling at the mouth of the rainforest.

Despite the setbacks, some nations like India praised the agreement, indicating a step forward in the global climate dialogue. Nevertheless, for many indigenous communities and environmental advocates, the failure to confront fossil fuel dependencies signifies a continual struggle for climate justice and preservation of their lands.
