The European Union has announced a significant reduction in its carbon emissions target, aiming for a 90% cut by 2040. This decision, made just before the U.N. climate summit in Brazil, has sparked criticism as it appears to dilute the bloc's previous commitments to combat climate change. Critics argue that the EU's plan to purchase carbon credits from less-developed countries undermines its responsibilities and could hinder global climate efforts. This development is crucial as it raises questions about the EU's leadership role in addressing climate change on the world stage.
