This assessment completed by FTI Consulting, Inc. for the Alliance for Market Solutions evaluated the impact of a carbon tax on the federal budget, carbon dioxide emissions, U.S. and state economies, and major industries from 2019 through 2028 by analyzing the baseline scenario and a scenario with a national carbon tax implemented. FTI Consulting used data and results from their analyses incorporating the PLEXOS electricity model and the Carbon Tax Assessment Model as inputs in the REMI model. Doing this allowed researchers to generate the economic impact of a national carbon tax and tax reforms, including demand for fossil fuel inputs, EITE rebates, and capital investments in the power generation sector. The comprehensive results from this evaluation were compiled and explained in terms of fiscal, economic, emissions, power sector, state, and industry impacts. By 2028, the carbon tax and reforms would have little effect on gross domestic product and the federal deficit while considerably reducing carbon dioxide emissions and improving air quality in the United States.
