The entire humanity, including the European Union, is facing problems caused by environmental pollution, resulting in unfavourable environmental changes. Given the negative ecological trend, it is evidently necessary to integrate and develop ecosystems through the application of European Union policies in the fight against the consequences of climate change. The main objective of the environmental protection policy is to reduce pollution by applying multiple instruments that will encourage both individuals and companies, and entire member states of the European Union, to reduce pollution levels. In 2019, the Council of the European Union and the European Council launched the European Green Deal initiative, aimed at allowing the EU member states to influence climate change through joint measures and policies. The European Union's climate policy initiative and legislation coherent with climate goals are integrated through the Fit for 55 package, the European Climate Regulations, the European Union Strategy for Adaptation to Climate Change, CO2 Emissions from Transport, the European Union Emissions Trading System, the Effort Sharing Regulation, the Land Use and Forestry Regulation, and the Clean Energy Strategy. In accordance with the European Union policy, it is necessary for the governments of all EU member states to introduce these legislative policies and initiatives. To protect natural resources, it is essential to use them optimally, including the reduction or, if possible, the complete elimination of negative, undesirable effects. To ensure direct influence and progress, the member states of the European Union, and their governments, should adopt a modern approach to environmental protection to achieve satisfactory results in reducing pollution and thus contribute to environmental protection.
