>Every person on the planet should have a carbon consumption rating and have exponential taxes applied accordingly. Anyone know how practical it might be to have a "progressive" carbon tax, similar in nature to a progressive income tax? I can't think of a good way to measure individual carbon-dioxide generation offhand, but that doesn't mean that there isn't. Maybe in a piecemeal fashion? Bringing back carbon based Luxury taxes on airline tickets, with a $100 tax on the first transoceanic flight, $200 for the second, $400 for the third, etc.?
