Yes, I am.
California actually has a low-carbon fuel standard that it put forward and finalized this past summer.
There was a letter that was sent by Congressman Waxman. His provision was included in another piece of legislation. I don't know if that has been fully implemented at this point.
I think of more direct concern would be the low-carbon fuel standard that California has put forward and which 17 other states have said they will try to implement as well.
