We've written fairly extensively about the climate change policy mechanism called cap-and-trade. And to be honest, not all of it has been positive.

We've critiqued cap-and-trade for not being clear or explained well,  we've come up with reasons a cap-and-trade is inferior to a carbon tax. And most recently, we wrote about a new poll that shows Americans prefer a carbon tax over a cap-and-trade by a margin of 2-1 (though we weren't critical there, just reporting poll results).

Taken all together you might think we were crazy-staunch advocates of a carbon tax -- but we're not (necessarily). We just want a policy that works and that can get through our painfully-incremental legislative system in the U.S.

So,  in an effort to provide more balance on the matter, we bring you, "The Facts of Cap and Trade." Put out by a group called Clean Energy Works and featuring environmental economist and climate expert, Nat Keohane, "The Facts of Cap-and-Trade" does an excellent job of breaking down the policy in a clear, understandable and entertaining way.

With some help from a team of animators, Keohane's video is clearly produced as a sort of alternative or rebuttal to Annie Leonard's,  "The Story of Cap and Trade," which, needless to say, paints a much less rosy picture than does Keohane. Regardless of where you stand -- and especially if you don't know where you stand -- you should watch this, you'll be glad you did.
