Carbon tax profile for Idaho (Ron Adkins)

Idaho State
% 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 in Idaho State in 2007 were considerably lower than the U.S. average, which was 21.0 short tons per capita.[4] This was probably because about 80% of Idaho's electricity comes from Hydroelectric power plants. Interestingly, Idaho's per capita energy consumption is close to the national average, due to an energy intensive economy.[5]

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 $486 million in 2007 (about $314 per person), assuming a 10% reduction in emissions.

Idaho currently has a motor fules tax, for gasoline and ethanol blends it is at $.25, it also taxes many other motor vehicle fuels. In 2007 this tax brought in about $234 million. Individual Income tax brought in $1.6 billion, and Sales and Use tax brought in nearly $1.3 billion. A carbon tax of $30 per short ton of CO2 (assuming a 10% reduction in emissions) could have reduced state income taxes about 30%.[6]
