The 2030 agenda for Sustainable Development, was adopted by all UN member states in 2015.  At its heart are the Sustainable Development Goals, which are an urgent call for action by all countries. The City-transformers initiative has special focus on Goal 11: Make Cities and human settlements inclusive, safe, resilient and sustainable.


During the C40 Mayors Summit in Copenhagen

City-Transformers and changeleaders from around the world gathered on Youth Island

to explore how we can transform our cities – and pave the way for a sustainable future.

We want to get more folks moving in sync across borders and cultures to make those 17 goals a reality.

For inspiration, have a look at this video, where Martin Keller, from Copenhagen City’s Department for Sustainable Development, performs his song “Sustainable City” with kids from Randersgade School in Denmark.
