Wherein, To My Great Surprise, I actually Agree with James Hansen
James Hansen wrote an editorial supporting a revenue-neutral carbon tax, and while I don't really agree with all of his justifications or economics, I do agree with his ultimate conclusion --that such a tax would be fairer, more efficient, less growth-killing, and ultimately more effective than the Frankenstein mess of parts that makes up the current cap-and-trade bill.
To be fair, I have been on this point for a while, having advocated a carbon tax offset by a payroll tax reduction to make it revenue neutral for some time, including in my most recent film. I don't think I have to tell my readers that I am not big on taxes nor am I of the belief that any strong action on CO2 emissions is necessary.
However, I am largely indifferent between a sales tax on fuel and an equal sized sales tax on labor (which is effectively what payroll taxes are). There is no doubt that a reduction in payroll taxes would be a helpful step in this recession, and if folks would sleep better at night with less carbon emissions, I can tolerate trading one for another.
Jonathon Adler has more, including Paul Krugman's negative reaction to the plan (did this guy really once win the Nobel Price in economics?)
