Supporting climate innovators.

The Climate Intervention Environmental Impact Fund supports and advises innovative investigators across the world who are working to reverse climate change.

We do this by making grants solely to support predictive environmental impact assessments (EIA), impact modeling studies, and stakeholder engagement efforts for small-scale field tests of new technologies. Next application deadline for three grants of $75,000 each: December 1, 2026. We believe that independent, objective EIA is vital for progress on climate interventions.
