Greenhouse Gas Reduction
Explorer

The “Gold Standard” tool for evaluating carbon policies in Washington State

The Explorer is our proprietary tool to analyze policy proposals aiming to lower greenhouse gas (GHG) emissions. The model has been reviewed by the Washington Departments of Commerce and Ecology for accuracy, featured in multiple legislative hearings, and used extensively by lawmakers and stakeholders to guide the development of policy. The Explorer is built upon the state’s Carbon Tax Assessment Model (CTAM), with layers of customization which allow policy design considerations to be quickly and cleanly evaluated, either individually or in aggregate, providing a range of tightly and responsively linked outputs.  For an example, please see our analysis of SB 6203, which was considered during the 2018 Legislative Session.
