Push the technology and policy changes needed to achieve a zero-emissions, high-energy planet at an affordable cost.
A $1,576,848 grant to Efi Foundation for nuclear scaling is the clearest signal in Clean Air Task Force Inc’s recent giving: this funder backs technical and policy work aimed at deploying zero-emissions energy at scale. The foundation’s portfolio pairs large grants with a strong policy orientation, supporting organizations that work on clean air, public education, decarbonization, and climate strategy. It also invests in the infrastructure around those goals, including roundtables, education, and sector-specific analysis. Among the larger recent awards are $740,000 to Catf Action Inc for advance clean air and $305,000 to Policy Impact for public education. Other grants point to a broad climate and energy agenda that includes nuclear energy, renewable energy, inflation-reduction policy, and global decarbonization work. The presence of grants to institutions such as Princeton University, the Atlantic Council, and the Massachusetts Institute of Technology shows a mix of research, convening, and policy engagement. Clean Air Task Force Inc’s giving is national in scope and organized around climate and energy systems change rather than direct service delivery.
Clean Air Task Force Inc funds a wide set of climate and energy topics, but several themes appear repeatedly in the recent grants. In nuclear energy, they gave $1,576,848 to Efi Foundation for nuclear scaling and $100,000 to Massachusetts Institute of Technology for nuclear energy education, indicating support for both deployment and knowledge-building. On decarbonization, the foundation awarded $100,000 to Center for Climate and Energy Soutions for decarbonization and $83,333 to Trustees of Princeton University for decarbonization. For policy and public engagement, they gave $305,000 to Policy Impact for public education and $100,000 to Atlantic Council for roundtables. Climate diplomacy and international work also appear in the record: the Deep South Center for Env Justice received $125,000 for COP27 climate, and Atlantic Council received $10,000 for a COP28 initiative. These grants show a mix of research, advocacy, education, and convening.
Typical grants cluster tightly around six figures: the p25 is $65,000, the median is $100,000, and the p75 is also $100,000. The recent record includes both one-time and repeated support: Catf Action Inc appears in 2023 and 2024, Atlantic Council in 2023, 2024, and 2025, Princeton University in 2024 and 2025, and Energy and Environmental Economics in 2024 and 2025. Clean Air Task Force Inc is a regular funder, not a DAF, and it does not fund individuals or make program-related investments. An active fellowship program, CATF CEE Fellowship, also shows a structured capacity-building approach.

Grant recipients are concentrated in the United States, with 21 grants to U.S. organizations. Massachusetts appears often in the recent grants, including Boston, Cambridge, and Brewster, while Washington, DC also shows up repeatedly through several recipients. Other visible recipient locations include Berkeley and Anaheim in California, Princeton in New Jersey, and New Orleans in Louisiana. The top state by grant count is Maine, which differs from the foundation’s Boston headquarters and suggests a giving footprint that reaches beyond its home state.
The recent grants point to climate and energy systems work: nuclear scaling, clean air, public education, decarbonization, inflation reduction policy, fusion establishment, renewable energy, and COP-related climate work. The foundation also supports convening and education, including roundtables and nuclear energy education.
The grant-size distribution is tightly centered on six-figure awards. The p25 is $65,000, the median is $100,000, and the p75 is also $100,000, which indicates that many grants land at or near $100,000.
