These briefs are part of a series on frontrunning climate actions around the world. The series aims to strengthen the evidence on the economic and social implications of low-carbon, climate-resilient urban development, highlighting the preconditions for the successful design and delivery of urban climate action, as well as outlining national policy recommendations that could enhance the initiatives’ impact. All publications published in the series so far are available here.
