Carbon tax profile for Ohio (Evan Young)

% change 1990-2007
Fossil fuel CO2 emissions, in millions of metric tonnes[1]
Fossil fuel CO2 emissions, in millions of short tons[2]
Population, in millions[3]
Per capita CO2 emissions, in short tons

Per capita emissions for Ohio in 2007 were slightly above the U.S. average of 21.0 short tons per capita.[4] The reasons mostly revolve around the amount of large emitting industry still found in Ohio and the lack of renewable power. [5]

Considering the size of the industrial sector and the availability of coal a potentially more interesting question is why Ohio's emissions are not higher. The answer seems to be two converging trends: the relative decline of industry as a significant piece of Ohio's economy and fuel switching from heavily emitting coal to relatively lower emitting natural gas (see figure below). [6]


A carbon tax of $30 per short ton of CO2 (about $0.30 per gallon of gasoline, or about $0.03 per kWh of coal-fired power) would have raised about $8 billion in 2007 (about $695 per person), assuming a 10% reduction in emissions.

For reference, in 2007 (FY08) Ohio generated $9bn from income tax and $7bn from sales tax as part of a $21bn revenue stream.[7] With the revenue from a carbon tax Ohio could have eliminated their entire sales tax.
