Clean Air Task Force: Top Climate Nonprofit Spotlight

Giving Green classifies Clean Air Task Force (CATF) as one of our top nonprofits for addressing climate change. We have recommended CATF since 2020.

CATF has a history of successfully advocating for a wide array of climate provisions, most prominently in the U.S. and EU. CATF focuses on clean technologies that are either nascent or lack broad support from civil society. By raising awareness and advocating for favorable policies in these neglected areas, we think CATF can accelerate decarbonization in sectors that might otherwise struggle to secure funding.

We have been impressed by CATF’s technical analysis, stakeholder engagement, and policy research and education. CATF has decades of experience influencing U.S. policy, while remaining agile in its focus areas to ensure impact is continuously maximized across changing technological and policy landscapes. CATF has played a substantial role in securing key historic climate policies, including wins in the Infrastructure Investment and Jobs Act (IIJA) and the Global Methane Pledge. It continues to adapt its strategies to current social and political conditions, most recently by launching a program to accelerate deep decarbonization of the electricity system. The program promotes practical solutions with bipartisan support, such as advancing clean firm technologies and streamlining regulations for faster clean energy deployment.

While we have not assessed all of CATF’s program areas in detail, our recommendation is based mostly on its work on decarbonizing the grid, superhot rock geothermal energy, aviation, and shipping—we are confident in its overall effectiveness and recommend unrestricted funding. 

For more information, see our Nonprofit Evaluation report, a summary below, and our broader strategy reports on unleashing clean energy in the U.S., and reducing maritime shipping and aviation emissions.

CATF has 501(c)(3) and 501(c)(4) entities. As Giving Green is itself a charitable, tax-exempt organization, we are only offering an opinion on the charitable activities of CATF’s 501(c)(3) arm, and not on CATF’s 501(c)(4) entity.
