Out of all international organisations, the EU is considered to have some of the most extensive climate protection laws, and it is regarded as a regional and global leader in environmental protection. Nonetheless, the process of EU decision-making can be notoriously overwhelming for citizens to engage with the process, or to appreciate it. It takes place at multiple levels, and involves several bodies and representatives from twenty-seven countries. In short, the EU is often regarded as complex precisely because of its inclusivity, its long history of evolving bureaucracy and flexibility, as well as its commitment to reach agreement among all stakeholders. To properly understand how policy-making works, it is necessary to first understand the role which is played by each of the EU institutions.
