Effects of U.S. Tax Policy on Greenhouse Gas Emissions

According to this report, the U.S. tax code is so complex it appears to have only a miniscule effect on greenhouse gas emissions. However, the authors leave open the possibility that a pricing scheme aimed directly at greenhouse gas emissions — either a carbon tax or tradable emissions allowances — would work more efficiently at lowering carbon emissions.

NRC says some of the report’s limitations include heavy reliance on modeling of U.S. rather than global impacts of tax code provisions, and economic models that could understate the innovation spurred by some tax breaks.
