The places we live and work are some of the greatest contributors to climate change. Buildings generate over half of the total greenhouse gas emissions for most cities, and in some cities, like London and Paris, it’s closer to 70 percent. A new mayoral coalition made up of 19 cities worldwide would require all new buildings to produce as much energy as they consume.
Today, 19 mayors from the C40 group signed a pledge to make all new buildings net-zero carbon by 2030. The mayors—including those of U.S. cities Los Angeles, New York City, Portland, San Francisco, San Jose, Santa Monica, and Washington D.C.—also pledge that by 2050, all buildings, old or new, will be net-zero as well.
