In case you missed it, washingtonpost.com featured a set of graphics about a carbon cap on its home page all last weekend. A couple of them looked very familiar to us. [Take a look](http://www.washingtonpost.com/wp-dyn/content/graphic/2009/02/26/GR2009022600572.html "Graphics on Washingtonpost.com").

We’ve been using a graph that tracks the price of emitting acid rain (sulfur dioxide) pollution for years now — [like on this page, on how a cap works](http://www.edf.org/article.cfm?contentID=9112). Which of these illustrations do you think are most useful?

I was also intrigued by a post by Eric de Place over on Grist. He describes a cap on carbon pollution as a “[magic self-adjusting carbon tax](http://gristmill.grist.org/story/2009/2/2/9857/99433).” It’s a nice explanation of a cap’s price flexibility, which is one of its key advantages.
