Cities Are Pledging To Confront Climate Change, But Are Their Actions Working?

Since 1991, over 600 local governments in the United States have developed climate action plans that include greenhouse gas inventories and reduction targets, reflecting growing public concern about the consequences of a warmer planet. Recently, this local action has been accelerating. A team of scholars organized by the Brookings Institution has built and analyzed one of the most comprehensive statistical evaluations of just what’s happening in a cross section of diverse cities on emissions reductions. Unlike earlier studies—which tend to focus only on the places that have made climate pledges—these scholars looked at all of the nation’s 100 largest cities to get a dose of realism about how much of the country is really engaged in confronting climate change. As of 2017, only 45 of the 100 largest cities had any serious climate pledge at all, and many of those pledges are more aspirational than realistic.
