Residents of the 100 largest metropolitan areas in the United States emit less carbon dioxide pollution per capita than the U.S. average, according to a new study. The Brookings Institution analyzed data on household and transportation energy use and found that the average U.S. resident was responsible for about 2.87 tons of carbon pollution a year, but that residents of the U.S.'s 100 largest metro areas had footprints of just 2.47 tons a year on average. Among the 100 largest cities, Honolulu residents were responsible for the least per capita emissions: about 1.5 tons per person per year. Lexington, Ky., fared the worst among the ranked cities with about 3.81 tons of CO2 per person per year. Overall, West Coast cities fared better than Eastern ones due to warmer climates, more aggressive energy-reduction policies, higher fuel and electricity costs, and a greater reliance on hydropower. To lower everyone's footprint, the study authors recommended increasing funding for mass transit and clean-energy R&D, and passing federal legislation to put a price on carbon emissions.
