The Green City Accord (GCA) is a movement of European cities committed to becoming greener, cleaner and healthier places to live. It provides a framework that empowers cities to tackle pressing environmental challenges and accelerate the implementation of the European Green Deal and the EU environmental law.
Why should cities join the Green City Accord?
By signing the GCA, cities take the lead in improving Europe's natural environment and quality of life while actively supporting the European Green Deal and the delivery of the Sustainable Development Goals.
As a signatory, cities will:
- connect with like-minded cities driving the transition towards a clean and healthy Europe;
- gain Europe-wide recognition of their environmental actions and achievements;
- increase transparency, accountability and credibility within the local community;
- gain access to information concerning EU funding opportunities;
- strengthen their chances of being awarded European Green Capital or European Green Leaf;
- participate in events, exchanges of best practices and join capacity-building opportunities; and
- receive tailored guidance and support.
The Green City Accord complements the Covenant of Mayors for Climate and Energy, as climatic and environmental action are deeply intertwined.

“Almost five years ago we launched the European Green Deal – our growth strategy and roadmap to net zero. The reasons which pushed us to be so ambitious then are even more pronounced today. So I want to be clear: We must and will stay the course on the goals of the European Green Deal. But if we want to be successful in this transition, we must be more agile and better accompany people and business along the way.”
