Low gas prices are pumping up sales of SUVs and trucks. And since transportation accounts for almost a third of America’s greenhouse gasses, that’s bad news for the climate. But America is awash in big ideas for how to create a healthy economy and healthy communities. One idea is to put a price on carbon. Everyone from oil companies to environmentalists are talking about what might happen if consumers paid the real price for coal and gasoline. Some think it just might boost the economy while also trimming carbon pollution.
