Though historically a taboo subject, the possibility of a carbon tax on large-scale polluters has resurfaced in a number of venues.
A recent report by the Congressional Research Service estimated a tax of $20 per metric ton of CO2 emissions could reduce the federal deficit by 50 percent in the next decade. The National Academy of Sciences is also working on a carbon tax analysis, which will be presented to Congress this spring. Additionally, a group of non-governmental organizations will hold a conference this week entitled "Economics of Carbon Taxes." Recently, a number of moderate Republicans have demonstrated support for a carbon tax, suggesting a bipartisan agreement may be possible in the future.
