Environment & Energy · Jun 30, 2026

Targeted cool-roof planning using building-level albedo data could cut extreme urban heat by up to 0.5°C globally by prioritizing low-reflectivity, large-footprint roofs rather than blanket programs, improving mitigation effectiveness and the economics for planners, investors, builders and property operators—notably in cities like London, Athens, Rio de Janeiro, Los Angeles, and New York City.
