Carbon tax profile for Mississippi (Daniel Bascom; previous version byFaith Wimberley)

% 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

In 2007, per capita emissions in Mississippi were just higher than the U.S. average, which was 22.4 short tons per capita.[4] This may be due to Mississippi's heavy reliance on electricity for residential air conditioning and heating.[5] Mississippi is energy rich, but even with a sizable supply, it must import energy from neighboring states to meet high demand.

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 $1.8 billion in 2007 (about $614 per person), assuming a 20% reduction in emissions.

Regarding the State's tax structure, In 2007 the state's highest revenue generating taxes were: sales (42% or $1,930,538,054), income (31% or $1,475,359,128), and corporate (10% or $484,714,153).[6] So a carbon tax of $30 per short ton of CO2 could (assuming a 20% reduction in emissions) have replaced the state income tax with 325 million remaining or could have replaced 93% of the state sales tax or could have replaced the state corporate tax with 1.3 billion remaining.

Factors to consider when strategizing the reduction of Mississippi's CO2 emissions from residential energy use include:
- Mississippi is the poorest state in the U.S.A.[7]
- Mississippi has the lowest cost of living of any state in the U.S.A.[8]
- Mississippi has the lowest per capita income of any state in the U.S.A.[9]
- Manufacturing has replaced agriculture as the primary industry.[10]
- Mississippi has very little environmental initiatives compared to other states.[11]

These factors may show that initiatives aimed at reducing CO2 emissions in Mississippi may be of little interest to Mississippians considering recent reliance on manufacturing, and little effort towards environmental conservation. Furthermore, CO2 emissions regulation aimed at reducing costs to individual households through the replacement of income or sales tax with a carbon tax may, in the end, have little effect on households as they rely heavily on heating and cooling, and considering the rate of poverty in Mississippi, likely are inelastic to energy consumption. Finally, little can be done to impact Mississippi's carbon emission rates without working regionally with states that import energy to Mississippi. Imposing a carbon tax in Mississippi will need to be executed in such a way that supports the fragile and transitional economy, reduces or improves widespread poverty, and addresses the weak investment in environmental sustainability.
