Cities endorse the Mannheim Message

The Mannheim Message, a collective response by cities to the European Green Deal, was finalised by European Mayors on 21 September 2020 and was formally presented to the European Commission on 1 October 2020 as part of the 9th European Conference on Sustainable Cities & Towns, organised by ICLEI Europe and the City of Mannheim (Germany). It builds on and bolsters the transformative actions catalysed by the Basque Declaration (2016).

Further, it calls for local authorities to be key partners in the development of Local Green Deals and the European Green Deal, to be used as key tools to facilitate this transformation.

In order to successfully develop and implement local Green deals, public procurement plays a significant role to drive innovation and market transformation and to reach societal and environmental goals

The development of the Mannheim message was  led by ICLEI - Local Governments for Sustainability and the City of Mannheim, with support from the Committee of the Regions and input from Mayors from across Europe.
