Per capita emissions in Washington State in 2007 were considerably lower than the U.S. average, which was 19.1 short tons per capita.[4] This was probably because of the extensive use of hydropower for electricity in Washington State.[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 $2.5 billion in 2007 (about $380 per person), assuming a 10% reduction in emissions.

For comparison purposes, annual estimates based on estimates for the fiscal years 2007-2009 are that the state portion of the property tax generated about $1.7 billion/year, the state B&O (business) tax generated about $3.0 billion, and the state sales tax generated about $7.6 billion.[6] So a carbon tax of $30 per short ton of CO2 could (assuming a 10% reduction in emissions) have more than replaced the state portion of the property tax or could have replaced 83% of the state B&O tax or could have replaced 33% of the state sales tax.
