Of course, public transportation produces pollution, too, but many transportation authorities are working tirelessly to reduce those emissions as much as possible. As of 2009, for instance, 29 percent of America’s public buses ran on alternative fuels, marking a nearly 200 percent increase since the year 2000, say U.S. Federal Transit Administration (FTA) officials. A car that runs on biodiesel or hydrogen certainly helps the environment, but a fleet of buses doing the same makes an exponentially larger impact.
