Sightline is very pleased to be hosting a new analytical paper and model, “Washington State Carbon Tax: Fiscal and Environmental Impacts” by Keibun Mori, a recent graduate of the University of Washington’s Evans School of Public Affairs. He created the Carbon Tax Analysis Model (C-TAM), for the Washington State Department of Commerce.
It’s an impressive piece of work on several levels. Mori’s analysis, which centers on a British Columbia-style carbon tax, is almost certainly the most comprehensive published treatment of a state-level carbon tax in Washington, and maybe anywhere. Even better, his spreadsheet-based C-TAM model manages to be open-source and comprehensible, but still allow for a remarkable degree of complexity and user input. Mori includes a terrifically thorough treatment of fuel prices and demand elasticity (which is a subject of much debate and confusion in climate geek circles). The result is a solid look at the economic effects and environmental benefits of a state carbon tax in Washington.
