Several major European cities from across the EU and beyond including cities such as Ghent (Belgium); Prague (Czechia); Copenhagen (Denmark); Helsinki, Tampere and Turku (Finland); Grenoble (France); Freiburg im Breisgau (Germany); Budapest (Hungary); Florence (Italy); Oslo (Norway); Ljubljana and Maribor (Slovenia); Seville (Spain), and Malmö and Umeå (Sweden) have joined forces to act on the transition to a circular economy by signing the European Circular Cities Declaration. Signatories recognise the need of accelerating the transition from a linear to a circular economy in Europe, and are committed to act as ambassadors and champion a circular economy that leads to a resource-efficient, low-carbon and socially responsible society, in which resource consumption is decoupled from economic growth. The Declaration has been launched by Anni Sinnemäki, Helsinki’s Deputy Mayor for Urban Environment at the 9th European Conference on Sustainable Cities & Towns – Mannheim2020. Launching signatories invite cities and regions from across Europe to join them in signing the Declaration. The Declaration has been developed by a broad group of European organisations committed to enabling the transition to a circular economy at the local level, including ICLEI – Local Governments for Sustainability, Circular Flanders, CSCP, ECERA, the European Investment Bank (EIB), Ellen McArthur Foundation, Eurocities, LWARB, UN Environment Programme and the WCYCLE Institute.
