• Cities neglect climate change risks due to a lack of scientific assessments
• There is an urgent need to integrate climate risk into city development strategies and plans
• The Climate and Cities Program fills this gap


• To reduce climate risk in developing-country cities through city-specific climate risk assessments, and by crafting flexible adaptation and mitigation strategies to leverage existing and planned investments
• To develop a global, institutional structure for integrating climate risk assessments into city development

Our Approach

Track 1

Global Progress Assessment: To develop state-of-the-knowledge assessments on climate change and cities.

Track 2

National – Across-city rapid climate risk assessments: To provide national city-specific rapid climate risk assessment of city development strategies and urban poverty programs.

Track 3

City Level – City-specific, in-depth impacts assessments:To craft city-specific risk assessments, for adaptation and mitigation mechanisms in each sector as well as to identify co-benefits and integrated impacts.

Track 4

Knowledge Sharing – Learning from doers: To derive adaptation and mitigation lessons from early adopters—such as London, Mexico, and New York—for knowledge sharing and capacity building.
