Currently, more than half of the world's population lives in cities, a figure expected to rise to nearly 70% by 2050. According to data from the United Nations (2017), the majority of this construction will be concentrated in cities across Africa, Asia, and Latin America.
As such, cities play a central role in climate change, as they are both the primary sources of greenhouse gas (GHG) emissions from human activity and the places where many of the impacts will be felt.
