A study from the George C. Marshall Institute tries to quantify the costs of a cap-and-trade plan to reduce carbon emissions. They're not small, to say the least: And although this study uses 2008 as a baseline, the Obama plan would hit in 2012 and could come in combo with a hike in investment and incomes taxes for wealthier Americans and the creation of a special healthcare tax:
The authors find that the constraints posed by the Lieberman-Warner cap-and-trade approach is equivalent to a constant (in percentage terms) consumption decrease of about 1% each year, continuing to 2050. Put another way, the cap-and-trade approach is the equivalent of a permanent tax increase for the average American household, which was estimated to be $1,100 in 2008, would rise to $1,437 by 2015, to $1,979 in 2030, and $2,979 in 2050.
Reviewing a host of recent studies, Buckley and Mityakov show that estimates of job losses attributable to cap-and-trade range in the hundreds of thousands. The price for energy paid by the American consumer also will rise. The studies reviewed showed electricity prices jumping 5-15% by 2015, natural gas prices up 12-50% by 2015, and gasoline prices up 9-145% by 2015. As an illustration, gasoline would suffer a 16 cent price increase per gallon at the low end of the estimates to a $2.58 penalty at the high end (using the January 2009 reported retail price of $1.78 per gallon).
