The Equation Campaign has received pledges totaling $30 million from Rockefeller family members Rebecca Rockefeller Lambert and Peter Gill Case, the Associated Press reports.

Launched in January 2020 and housed at the Rockefeller Family Fund, the ten-year funding initiative is dedicated to strengthening grassroots movements fighting to keep fossil fuels in the ground and eliminate the gas and oil industry's sources of financial support. As part of the campaign, grants will be awarded in support of strategic litigation and the legal defense of activists, as well as to counter the fossil fuel industry's deceptive practices. The initiative also will work to diversify the climate movement with voices not typically consulted in climate philanthropy, including Black, Indigenous, Latinx, and economically distressed communities as well as young people.

According to the AP and Chronicle of Philanthropy, an additional $5 million has been pledged to the effort by other groups, including the Open Society Foundations, the 11th Hour Project at the Schmidt Family Foundation, and the David Rockefeller Fund.

"It's time to invest more in Earth's principal, so that not just our children but the world's children can depend on homes that are reasonably safe from floods, fires, and war, so that they can depend on water to drink, land for crops, and live in a rich and biodiverse natural world," wrote Rockefeller Lambert on the Equation Campaign website. "For more than thirty years, corporate behemoths have had a stranglehold on climate progress. I'm interested in leveling the playing field for the those on the frontlines of climate change and the oil and gas expansion, who are rising up to protect our collective future."
