Real World Pigovians

Several readers have emailed me examples of the Pigou Club making headway in the real world (as opposed to the fantasy world of academia and op-ed pages):

• Boulder, Colorado, has just passed a carbon tax.
• Elizabeth May of Canada's Green Party has been advocating a carbon tax. I am told, "Unlike the party south of the border, the Canadian Greens are very fiscally conservative (May was an advisor to former Conservative PM BrianMulroney)."
• Christine Gregoire, governor of Washington state, signed into law an increase in the gas tax in 2005.

A meager start, but a start nonetheless.
