Maria Cantwell Washington Senator Maria Cantwell just came out in favor of “Cap and Dividend”—a system for curbing global warming gases by auctioning off a limited and declining number of carbon “permits”.  Good for her—we think that Congress should give Cap and Divident a close and sympathetic look. But one aspect of  this Tacoma Tribune article on Cantwell’s announcement is simply baffling; either Cantwell is confused or the newspaper is…

    Thanks to Jay Lazerwitz for supporting a sustainable Cascadia.

  • Here’s how the news report describes Cap and Dividend:

    It’s a relatively new approach that would eliminate the trading of emissions credits. The idea is for the government to cap carbon dioxide emissions. Companies that emit carbon dioxide would have to buy emissions allowances or permits.

    The money the government raises by selling the allowances could be rebated to taxpayers in the form of dividends.

    That’s about half wrong.   As it’s normally described, Cap and Dividend would allow trading of permits.  In fact, Cap and Dividend would work just like any other form of Cap and Trade.  What’s distinctive about Cap and Dividend is that it would auction off all permits, and give the revenue back to citizens on an equal per capita basis.  The tradeability of permits is an entirely separate issue from the auction-plus-rebate design that is the essence of Cap and Dividend. 

    Here at Sightline, we’re scratching our heads about how “untradeable” permits would work, either in theory or in practice.  Proponents of the idea are  concerned about the risk of speculative price runups in a poorly designed market.  But as far as I can tell, untradeable permits could increase the potential for speculation and windfall profits.  (More on that here.)
