The pie charts for electricity, jet fuel, etc. are similar, meaning that carbon
taxing can be made "income-progressive" via pro rata revenue distribution.

CTC’s proposed national carbon tax, $37 per ton of carbon ramped up each year for at
least 10 years, would reduce emissions by almost 4% annually — more than 30% by 2017.

Because CO2 stays “resident” in the atmosphere for at least a century, the U.S.
is responsible for more than 3x as much active greenhouse gas as China.

Because coal has the highest carbon content per Btu, it is
taxed at the heaviest rate under a straight carbon tax.
