The Thurston Climate Mitigation Plan will include a list of communitywide actions that aim to lower greenhouse gas emissions and help the region progress towards its adopted reduction targets. An initial list of actions was developed over the summer of 2019 with input from subject matter experts and public comments. In order to identify these actions, The Thurston Climate Mitigation Plan uses a Multicriteria Analysis to rank and prioritize communitywide actions. Input was generated from the consultant team, key stakeholders, and technical experts to qualitatively assess how each action could address the goals of the project, including the potential for each action to reduce greenhouse gas emissions. This was used to assemble a list of recommended actions that will be included in the plan draft. In order to assess how these actions would reduce our regional emissions, a Scenario Analysis Tool and User Guide were developed to measure their cumulative effect.
