In the EU, municipalities are increasingly developing “smart” solutions for urban infrastructures and their integration. Frequently, the vision of a “smart city” is portrayed as key for sustainable, climate friendly municipalities. Building on a German smart city stakeholder dialogue, the project intends to foster European dialogue and learning on smart cities for climate mitigation. The focus will be on the infrastructure sectors mobility, energy and waste management and water and their integration. Besides this sectoral focus, the project will address several issue areas, among them (1) governance (smart city strategies, processes, structures and actors), (2) monitoring and evaluation and (3) transfer of best practices. The project comprises Estonia, Latvia, Lithuania and Germany, as well as forerunner and follower municipalities. Four dialogues will be organized, one in each country.
