So Obama is so convinced of the economic benefits of a carbon tax, he is going to price it when?
These states already do... (Regional Greenhouse Gas Initiative)
California, Connecticut, Delaware, Maine, New Hampshire, New Jersey, New York, Vermont, Massachusetts, Rhode Island and Maryland,
These states are about to start on the 1st January 2012 (6 months before us): (Western Climate Initiative)
Arizona (USA), California (USA), New Mexico (USA), Oregon(USA), Washington (USA), Utah (USA), Montana (USA), British Columbia (Can), Manitoba (Can), Ontario (Can), and Quebec (Can).
BTW Obama is on the record supporting emissions trading, he just has no way to get it through Congress and the Senate. Much like 90% of what he would no doubt like to do but can't on the legislative front.
