The negative impacts of human activities on the environment and nature can be felt worldwide. Thus there is a growing focus on measurements that keep sustainability in mind. As one of the main pioneers of environmental protection and sustainability efforts, these aspects are more and more prevalent in the current environmental policy of the European Union (EU). In this review article, the development of the environmental policy of the EU is presented. After listing the main milestones, the role of the EU in the area of environmental protection, the frameworks built around the goals and the roles of the institutions are discussed. Then – with an international detour – the details of the Paris Agreement about climate change and the state of the 20/20/20 commitments are summarised. In the remaining parts of the article, the focus is on the climate protection goals of the EU for the next three decades, the expected future directions, and the agenda of the von der Leyen Commission concerning climate protection. An important step and tool for achieving the goals set until 2050 is to incorporate climate and environmental protection elements to the 2021-2027 budget of the EU. In order to achieve the expected effects, it is crucial to develop the right tools of the environmental policy, to form a widespread cooperation, to raise awareness, and incentivise and support the innovative solutions in the sustainability area.
