That is to say, the reality is you have a zilch chance of passing a carbon tax in the US government sufficient enough to facilitate the change you are hoping to see. The only way oil and gas goes for a carbon tax is if it ends up being a net benefit to them, and as long as there is oil to burn, I don't see that happening any time soon.
I would think California, for as progressive and liberal as it claims to be on the outset would pass something like this, but it's tough for me to be too optimistic there considering the influence and power Chevron has over the state.
