First held in 2013, Aalborg's Sustainability Festival is now one of the largest of its kind in Denmark. The annual Aalborg Sustainability Festival is a showcase for sustainability-related initiatives and ideas. It is a collaborative effort involving citizens, businesses, government, NGOs and other parties in an discussion of sustainability-related issues. It is one of the municipality's key events for spreading green ideas to citizens, while showing the public the diversity of sustainability projects that their city is undertaking.

Promoting sustainable behaviours, practices and thinking is a priority for the municipality, and is powered by the Centre for Green Transition, and our vision is that it should be easy for every citizen to be green in Aalborg. The Festival is also a key networking event for businesses and individuals, furthering the mission of the Centre for Green Transition to connect groups for a coordinated sustainable city transition.
