European countries have a significant impact on global climate change, with some contributing more than others. The Climate Change Performance Index (CCPI) identifies the worst polluters based on factors such as greenhouse gas emissions, climate policy, and energy use. In 2021, Germany, France, and Italy were the top GHG emitters in Europe, while Luxembourg, Ireland, and the Czech Republic had the highest per capita emissions. These countries exceeded 10 tonnes CO2 eq per capita and are not aligned with Paris Agreement goals.

Hungary and Poland stand out as the worst performers in climate policy evaluations, with Hungary receiving particularly low scores for both national and international policies. These countries hinder renewable energy deployment and show little progress in reducing emissions. Additionally, high energy use in countries like Finland, Luxembourg, and Sweden poses a challenge to decarbonization efforts. Despite some promising trends in emission reductions, more rapid action is crucial to combat the climate crisis effectively.
