In short, good things happened when we harnessed the tremendous power of the market to solve environmental problems. Today, the biggest and most pressing of those problems – identified, once again, by a massive amount of scientific research and evidence over several decades – is not acid rain, but global warming. And the proposed solution, once again, is the conservative, market-based "cap-and-trade" system. Strangely, however, it's conservative, market-based Republicans who have morphed into the loudest and most vociferous opponents of "cap-and-trade," while Democrats have become its biggest proponents.
Even stranger, as Climate Progress points out, many Republicans are now opposing – even "demagoguing" – against an idea they once supported! A short list includes: Sen. Lisa Murkowski (R-AK), who once said she supported cap-and-trade because she believed "it offers the opportunity to reduce carbon, at the least cost to society;" Sen. Scott Brown (R-MA), who once bragged that voting for "cap-and-trade" in Massachusetts was an "important step … towards improving our environment;" Sen. John McCain (R-AZ), who once asserted that cap-and-trade "will send a signal that will be heard and welcomed all across the American economy;" and Sen. Lindsey Graham (R-SC), who used to believe that we should "set emission standards and let the best technology win." Actually, as Steve Benen at Washington Monthly points out, the McCain-Palin official website in 2008 promised that a McCain administration would "establish…a cap-and-trade system that would reduce greenhouse gas emissions."
My, how times have changed in less than 2 years.
The point of all this is simple. Cap-and-trade is not some dastardly scheme to destroy the U.S. economy. Cap-and-trade is not radical, either. In fact, cap-and-trade is a tried, true, tested and proven, market-based approach to reducing greenhouse gas emissions at the lowest possible cost. It worked with acid rain, far faster and cheaper than anyone predicted. Why would it be any different with carbon dioxide than sulfur dioxide? And why would Republicans oppose their own idea, after watching it produce one of the biggest environmental victories in U.S. history, on the gravest environmental threat facing our country and our planet? Even more, why would Republicans oppose an idea that — even if you put aside the issue of global warming — is still imperative – for urgent economic (e.g., sending $400 billion overseas every year to pay for imported oil) and national security (sending that $400 billion to a lot of countries that aren't our friends, are building nuclear weapons programs, etc.) reasons?
It's hard to think of any good reasons, how about some bad ones? Because, in the end, that's about all the cap-and-trade naysayers have left.
