Carbon tax profile for Arizona (Vishnu Warrier; previous version byMichael Huynh)

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

Since 1990, CO2 emissions in Arizona increased faster than any other state in the nation (except Nevada?). This can be partly attributed to the population growth in the state which has ranked first or second since that time.[4] Per capita emissions actually declined from 1990 to 2007 and were lower than the U.S. average, which was 21.4 short tons per capita.[5] This can be attributed to Arizona's rapidly growing population since 1990 which changes the short ton to census ratio lowering the per capita CO2 emission.

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 2007 (about $430 per person), assuming a 20% reduction in emissions.

For comparison purposes, in the 2006-2007 Fiscal year the state portion of the income tax generated about $1,677,949,795 and the transaction privilege, use, and severance tax (TPT, kind of like a sales tax) generated about $7 billion.[6] So a carbon tax of $30 per short ton of CO2 could (assuming a 20% reduction in emissions) replace 18% of the state income tax or 43% of the TPT.
