Exxon realizes fully that a carbon tax and credits constitute a license to pollute. Huge corporations work the cost into their operating budget. Small companies go bankrupt. There was also mention of more tax credits for Exxon if they went along with this. Sadly, people are so uneducated they will actually think Exxon cares. Humans are not evolving when it comes to recognizing scams and ripoffs. Too bad for us all.
