Executive Summary

In this document, we provide a descriptive overview of Evergreen Collaborative’s activities and describe a quantitative cost-effectiveness analysis (CEA) model that assesses the organization’s marginal impact. Based on our assessment, we believe that Evergreen Collaborative’s work will likely reduce greenhouse gas emissions and that its legislative work at the federal level is especially cost-effective. We focused our analysis on Evergreen Collaborative’s work on influencing Congress given that the organization centered its 2021 efforts on the Build Back Better Act and the Clean Electricity Performance Plan in particular. Looking forward to 2022, Evergreen Collaborative is planning to work on regulation, bill implementation, state-level policy, and influencing the Executive Branch. We are cautiously optimistic that Evergreen Collaborative will be impactful in those areas as well given the organization’s track record of success and emphasis on timing its work to what is most politically tractable. Based on Evergreen Collaborative’s accomplishments, organizational strengths, strategic approach, and cost-effectiveness, we recommend Evergreen Collaborative as one of our top charities in combating climate change.


Evergreen Collaborative is a policy advocacy group that was founded by former staffers of Washington State Governor Jay Inslee’s 2020 presidential campaign. It designs and advocates for policy proposals while working alongside like-minded environmental organizations such as the Sunrise Movement and the Big Greens (e.g., large and well-funded environmental groups such as the Environmental Defense Fund). By working on policy advocacy and pooling resources with other organizations, Evergreen Collaborative seeks to influence Congress, the Executive Branch, and federal agencies. Evergreen Collaborative has developed blueprints and fact sheets for policy proposals such as the Clean Electricity Performance Program (CEPP), vehicle electrification, housing retrofits, and the Civilian Climate Corps. Many of these policy proposals have been in discussion for the Build Back Better Act. For example, the House Committee on Energy & Commerce has proposed and advanced the CEPP for the Build Back Better Act.
