European Union policies and their role in combating climate change over the years

The worrying environmental situation and increased public awareness in recent years have led many countries to take measures to reduce negative impacts on the environment. The European Union (EU) has been one of the most active in environmental protection with the formulation of policies aimed at preserving the health and well-being of citizens and protecting natural resources. One of the objectives of environmental policies is to make the economy of its member states more environmentally friendly, although this requires finding solutions to major challenges such as climate change, the scarcity of natural resources, the emission of polluting gases, and unsustainable consumption and production. This article reviews the main policies that have been implemented in the EU to reduce environmental problems and the scope of climate change conferences. It offers solutions to promote sustainability that could be adopted by companies, individuals, and governmental institutions to jointly contribute to achieving a more sustainable world, where problems such as climate change or the emission of polluting gases are minimized. The aim is to follow the principles of the Circular Economy and the European Green Deal.
