The European Union (EU) has taken significant steps in introducing new energy policies in response to increasingly urgent climate change. One of the most important initiatives is the European Green Deal, which aims to make Europe an environmentally friendly and sustainable continent. With a target to reduce greenhouse gas emissions by at least 55% by 2030 compared to 1990, this policy is an important milestone in the global effort to fight climate change. Within the framework of its new energy policy, the EU is encouraging a transition from fossil energy sources towards renewable energy, such as wind, solar and biomass. Investing heavily in green technology and infrastructure makes energy cleaner and more affordable. For example, offshore wind projects have been optimized to produce electricity more efficiently and with less environmental impact. In addition, the EU implemented an emissions trading system (ETS) that aims to incentivize companies to reduce their emissions. By setting strict emission limits and allowing trading of emissions permits, this policy encourages innovation and efficiency in the industrial sector. Significant emission reductions in the energy and transportation industries are also a key focus. The use of green hydrogen technology is also seeing a surge, with the EU investing in renewable energy-based hydrogen production as an alternative to fossil fuels. Green hydrogen has the potential to be a long-term solution for energy storage, transportation and heavy industry, making a major contribution to decarbonization. The EU also prioritizes the principle of sustainability in the use of resources, through strict regulations on energy efficiency and ecosystem preservation. The Circular Economy Policy Package launched supports waste reduction and promotes recycling, thereby minimizing the environmental impact of production and consumption. Within the framework of foreign policy, the EU is committed to collaborating with other countries in addressing climate change issues. By building international alliances, the European Union seeks to share technology and knowledge, and support developing countries in their energy transition. These efforts also include financial contributions to sustainable projects in countries most affected by climate change. The combination of these strategic steps shows the EU’s commitment to facing the challenge of climate change. By optimizing the use of renewable resources, introducing innovative technologies and collaborating internationally, the EU is determined to be a leader in the era of sustainable and environmentally friendly energy.
