Håkan Axelsson oversees Vattenfall's Sustainable Cities program, which aims to support cities in transitioning to sustainable energy use through energy solutions and coordinated internal and external work processes. The program initially focuses on cities where Vattenfall has a strong presence, such as Uppsala, Berlin, Hamburg, and Amsterdam. These cities account for around 241 TWh in total energy consumption annually, of which Vattenfall supplies around 70 TWh. The Sustainable Cities program seeks to reduce carbon emissions and support cities in achieving their sustainability goals.
