The European Union (EU) has been at the forefront of global efforts to fight climate change, with a range of ambitious green policies. One of their main initiatives is the European Green Deal, which aims to achieve carbon neutrality by 2050. This policy covers a wide range of sectors, from energy to transport and agriculture, focused on reducing greenhouse gas (GHG) emissions. The energy sector is a top priority in the EU’s green policy. Strategies to promote renewable energy, such as wind, solar and biomass, are strongly emphasized. The European Union has proposed to increase the target for the use of renewable energy to 40% of total energy consumption by 2030. This is expected to reduce dependence on fossil fuels and significantly reduce CO2 emissions. Transport is also an important focus in the EU’s climate change efforts. The European Commission plans to increase the use of electric vehicles and expand charging infrastructure. This policy is aimed at reducing emissions from the transportation sector, which is one of the largest contributors to GHG emissions. In addition, the EU encourages investment in more efficient and environmentally friendly public transport. Sustainable agriculture is also an integral part of a green strategy. The “Farm to Fork” initiative focuses on a more sustainable food system, with reduced use of pesticides and chemical fertilizers. This policy aims to protect biodiversity and improve soil quality, while ensuring food security. Investment in environmentally friendly technologies is one of the main drivers of the European Union’s green policy. The Horizon Europe program, which is the world’s largest research and innovation program, provides funding for research in low-carbon technologies and clean energy. This includes the development of more efficient batteries and energy storage technologies. The implementation of green policies is also closely related to social and economic aspects. The European Union developed the “Just Transition” principle to ensure that changes towards a green economy do not come at the expense of communities dependent on traditional industries. This approach includes training and education for affected workers, so they can adapt to new labor market demands. At the global level, the EU plays a leading role in climate negotiations, including within the framework of the Paris Agreement. The European Union is committed to increasing its emissions reduction ambitions at a global level and encouraging other countries to take more ambitious steps to achieve climate goals. With all these initiatives, the European Union shows that the transition to sustainability can be achieved through collaboration, innovation and integrated policies. Through progressive green policies, the European Union not only seeks to meet internal targets, but also provides inspiration and support for other countries in facing the challenge of climate change globally.
