Context
Global urbanisation is progressing rapidly. According to United Nations estimates, the urban population will more than double by 2050 and almost 7 out of 10 people will live in cities.
In order to accommodate and provide for all city residents, 60 per cent of the infrastructure still needs to be built. The energy and resource consumption associated with this would generate around three quarters of the global greenhouse gas emissions permitted under the Paris Agreement.
However, cities also hold the potential to overcome these challenges. Even small changes can have a big impact and reach many people at the same time.
