The new standards are a big deal—they’ll do more to cut the pollution of heat-trapping gasses than anything the Obama administration has done so far. But if it seems like you’ve heard about them before, you probably have—the regs got lots of press when they were first proposed last May<\/a>. Thursday’s action puts that plan into effect, for 2012-2016 vehicles.<\/p>\n <\/p>\n So I’m reposting our cheat sheet from last May<\/strong>, The scoop on Obama’s new fuel-economy rules<\/a>.
