Wait a second...now, the way I read this, the bill is a call for the reduction in greenhouse gases, and the tax and all are just suggestions (or scare tactics) of ways to comply with the law if it were passed.
While I confess that I haven't read the actual bill (not enough time at the moment to concentrate on any legal speak), this is the link of the state assembly...
