In working to help improve the climate resilience of Los Angeles with easy, common-sense policies to better our city, we launched a “Cool Roofs” campaign in 2012. A first step was bringing together dozens of experts, scientists, and leaders from across the country who are making great strides towards creating affordable climate solutions. At our March 2013 “Hot City, Cool Roofs” Conference, we were joined by then-Mayor Antonio Villaraigosa in planning next steps for how cool roofs can improve Los Angeles today, tomorrow, and over the next century. Climate Resolve and the participants of the conference identified a key takeaway from the conference: passing a law that to require all new and refurbished homes to have a cool roof. In December 2013, Los Angeles became the first large city to pass such a law, which was unanimously approved by LA City Council. “Keeping temperatures down on extreme heat days will protect lives; energy efficiency will save millions of dollars; and cool roofs will help Los Angeles combat global climate change at the local level,” said Climate Resolve’s Executive Director Jonathan Parfrey after the bill passed.
