Cities are increasingly seeking ways to become carbon neutral, climate-resilient, and biodiversity-rich. To support this, they can take advantage of their ample political power and less complex governance structure compared to the central or regional governments, to implement climate change mitigation and adaptation plans at the local level.
Cities need to develop mitigation plans for their transition to climate neutrality as well as adaptation plans to cope with the enhanced impacts of climate change. In both cases, they also need to be Climate Smart to exploit digital technologies in such sectors as transport, urban planning, energy distribution, and others.
This chapter exemplifies the factors above by referring to UIA projects related to emerging green sectors, as implemented in cities in the European Union. These UIA projects are examined in terms of their objectives, the barriers they have encountered, the key lessons that are emerging in terms of the green sectors, and the approaches to be replicated and scaled. Finally, key messages are drawn regarding the emerging green sectors.
