Hosted by the City of Mannheim, and ICLEI Europe, the European Conference on Sustainable Cities and Towns will open its doors for the 9th time from 30 September - 2 October 2020 in Mannheim, Germany.

The conference will demonstrate the urgent need for local governments to assume responsibility for urban transformation and lead the way in guiding Europe towards a secure and sustainable future. The world is facing major environmental, economic and social challenges that require a substantial transformation in all aspects of society. Without this transformation, global and European self-set goals like the Paris Agreement, the Sustainable Development Goals and the Europe long term strategy on GHG emission reduction will remain unreachable.


 Become part of a transformational movement.

Join over 800 participants from local and regional governments, European and international institutions, multilateral organisations, the research community, business and civil society.
