How can we shape urban development towards sustainable and prosperous futures? This course explores sustainable cities as engines for greening the economy. We place cities in the context of sustainable urban transformation and climate change. Sustainable urban transformation refers to structural transformation processes – multi-dimensional and radical change – that can effectively direct urban development towards ambitious sustainability and climate goals. We connect the key trends of urbanization, decarbonisation and sustainability. We examine visions, experiments and innovations in urban areas. We look at practices (what is happening in cities at present) and opportunities (what are the possibilities for cities going forwards into the future). We bring together a collection of diverse short films and key short readings on sustainable cities as well as interactive forums and a practical assignment to create an online learning community. This course provides key examples of activities to promote sustainable cities in Scandinavia, Europe and around the world. We utilize films and reports by WWF and ICLEI – Local Governments for Sustainability and ongoing research and innovation projects.
