This analysis published in the journal Climate Change Economics examines impacts of nationally-imposed carbon taxes on different regions of the United States. The goal is to see what can be learned about the drivers of regional political support for and opposition to such measures. Whether at the state, regional or national levels, carbon taxes are one option for reducing greenhouse gas emissions; several state and regional programs are already under way and lowering emissions. This analysis uses a U.S. regional version of the Dynamic Integrated Economy/Energy/Emissions Model (DIEM) computable general equilibrium model to explore relationships between carbon taxes, emissions, and economic growth. One area of emphasis is how the distribution of impacts may be affected by differences in regional household spending patterns, the types of industries and electricity generation situated in those regions, and the locations of energy production and energy-intensive manufacturing. The modeling also explores how carbon tax revenues can be used to offset impacts on regional factor earnings.
