Clean Air Task Force
Policy and technology advocacy targeting the highest-leverage climate and air pollution solutions
Our editorial assessment
CATF is consistently rated the most cost-effective climate charity by Founders Pledge and other giving researchers, with an estimated cost per tonne of CO₂ avoided of under $1 — orders of magnitude cheaper than most emissions reduction approaches. Their strategy is to focus on neglected, high-leverage solutions that other environmental groups avoid: methane regulation, advanced nuclear energy, carbon capture, and clean hydrogen. This willingness to champion politically unfashionable technologies makes CATF uniquely valuable in the climate space. Their policy work has influenced regulations affecting billions of tonnes of greenhouse gas emissions. For donors who want maximum climate impact per dollar and are comfortable with a technology-agnostic approach, CATF is the standout choice.
The problem they're solving
Reaching net-zero emissions requires more than just renewable energy. Methane is responsible for roughly 30% of global warming to date, and heavy industries like steel, cement, and shipping need technologies beyond wind and solar. CATF targets these critical gaps that other organisations neglect.

How this score was produced
The GiveWise score is our own editorial assessment, produced with a weighted rubric covering program spending, transparency and governance, evidence of impact, cost-effectiveness, and leadership. It draws on publicly available reports from independent evaluators such as GiveWell, Charity Navigator, and CharityWatch, but it is not a rating issued or endorsed by any of those organisations.
