Fossil fuel producers and power plant operators.<p>A few states, and therefore a motivated group of Senators, would be hit disproportionately hard.  Places like Wyoming and West Virginia drive a considerable part of their economy from coal, and fracking has led to natural gas windfalls in states like North Dakota.<p>You would imagine that some large carbon-intensive companies, like Koch or ExxonMobil, would also be impacted significantly.<p>EDIT:  The counterpoint is that a gas tax in particular is quite regressive.  The poor pay a larger portion of their income toward necessities like fuel to drive to work.  They also are less likely to be able to afford that Tesla.  Entry-level service workers can&#x27;t work from home.  They might be commuting large distances from cheaper outlying areas. There are many reasons why (if not managed properly) a carbon tax could hurt the wrong people.<p>It still seems like the right idea to me, though!  We need to avoid calling it a &#x27;tax&#x27; though, to avoid the Grover Norquist influence...
