"Urban Cooling Solutions Can Reduce Indoor and Outdoor Air Temperatures in Cities."

Cities are getting hotter as a result of growing urbanization and global climate change. The negative impacts of temperature increases are significant and touch nearly every aspect of urban life. Protecting populations from extreme heat is one of the key resiliency and sustainability challenges of the twenty-first century. Successfully implementing measures to cool cities will lead to many benefits, including health, well-being, productivity, air quality, and energy systems. Urban cooling solutions can be deployed in the short term to help mitigate the risk of rising urban air temperatures.

This Executive Summary outlines the different types of urban cooling solutions, the barriers to urban cooling, a framework for developing an urban cooling strategy, and recommendations to cities.
