Achieving climate neutrality has become an environmental goal for all European Union (EU) Member States. Thanks to numerous projects and subsidies, EU countries are able to achieve the goal of decarbonizing energy sources. The aim of the presented study is to assess the validity of Member States’ actions to reduce CO2 emissions based on data provided by Eurostat. The presented study combines, using regression, data on financial outlays dictated by environmental protection, the share of renewable energy, and total CO2 emissions in individual Member States. This study has shown that, despite differences in the use of energy sources, Member States are able to achieve economic growth in symbiosis with the environment.
