Carbon tax profile for Oklahoma (Kai Wang 2005)

% change 1990-2005
Fossil fuel CO2 emissions in millions of metric tons.[1]
In millions of short tons
Population in millions.[2]
Per capita CO2 emissions in short tons

Per capita emissions in Oklahoma in 2005 were 44.9% higher than the U.S. average, which was 21.4 short tons per capita.[3] This was probably because Oklahoma is one of the top natural gas-producing States but only has 1.2% of the nation's population.[4]

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 $2.8 billion in 2005 (about $795 per person), assuming a 20% reduction in emissions.

For comparison purposes, in 2005 the state portion of the income tax generated about $2.6 billion, the state business tax generated about $1.5 billion, and the state sales tax generated about $1.9 billion.[5] So a carbon tax of $30 per short ton of CO2 could (assuming a 20% reduction in emissions) have replaced the state portion of the income tax with $0.2 billion left over or the state B&O tax with $1.3 billion left over or the state sales tax with $0.9 billion left over.

Oklahoma may be one of the toughest state to carry out carbon tax. Its high use of air-conditioning, highly dependence on natural gas and electricity as house heating fuel, and political conservatism all militate against carbon taxing. Per capita consumption of natural gas and electricity in Oklahoma homes are both higher than the Nation average.[6] Especially for low and middle income family, they spend more proportional income on energy, that the tax shifting may lead poor to be poorer. Thus the success of fully protection of vulnerable family mechanism is particularly important to Oklahoma residents, including a refundable “energy tax credit” and an “energy refund”.[7] Also increasing home energy efficiency will also help Oklahoma family to save the budget.[8]
