Frontrunners: Policy briefs to inform national governments on the economic and social benefits of action for sustainable cities.

This paper analyses lessons from Kochi and Trivandrum, Kerala, India, where municipal government and community partnerships on house building projects have led to better quality new housing stock while reducing costs and environmental impacts. It finds that by placing participation at the heart of their processes, these cities have achieved 100 per cent occupancy rates at a lower cost, while also cutting carbon emissions and providing economic benefits. Nationwide, costs and occupancy levels of Kochi and Trivandrum could save Rs. 118 billion (US$1.71 billion), or build an additional 816,000 homes.

This policy brief is one of a series: ‘Frontrunners’, on innovative climate actions in cities around the world. The objective of this series is to strengthen the evidence on the economic and social implications of low-carbon, climate-resilient urban development. The series focuses on providing robust data on actual or ex post outcomes of climate action, ranging from better public health to job creation to greater equity. Each case study explores some of the preconditions for the successful design and delivery of urban climate action and provides national policy recommendations that could enhance their effectiveness and benefits.
