Our Research

Why US Policy Change?

Fighting the climate crisis requires systemic change that can only be achieved through government policy. We believe that the most effective giving opportunities are organizations working to enact systemic policy change. The United States, as a leader on the global stage and the world’s second-largest emitter, holds immense power and responsibility to shape the global fight against climate change. The US is also the largest global funder of research and development, so its actions can have global impact.

We focus on organizations that are directly working to change US federal policy, through legislation, executive action, and regulation. We have considered organizations that use “insider” tactics, such as research and policy drafting, as well as “outsider” tactics, such as grassroots activism. Donations to our recommended US policy organizations are tax-deductible in the US.

We currently recommend three policy change organizations: Carbon180, Clean Air Task Force, and Evergreen Collaborative.
