Republican presidential candidate Mitt Romney, like his fellow GOP contenders, supports unlimited coal and oil production and opposes cap-and-trade markets to limit greenhouse pollution. Romney calls cap-and-trade a “radical feel-good” policy that would have “devastating results for people across the planet.” Last month, he told Fox News that the nation needed to “start drilling for oil” and to “use our coal resources” because “you have to have oil and gas to power America’s economy.”

But according to his standards, Romney himself used to be a “radical” environmentalist who supported clean energy policy and opposed a pollution-backed economy. Back in 2005, Romney told the Boston Globe he was “convinced” that cap-and-trade was “good business.” It was his administration, in fact, that helped guide the development of the Regional Greenhouse Gas Initiative, a cap-and-trade system in the Northeastern U.S. that has raised $860 million for energy efficiency and renewable energy programs.
