The U.S. Environmental Protection Agency teamed up with the Department of Government Efficiency to put the kibosh on more than $67 million in grant money once earmarked to push ex-President Joe Biden’s “environmental justice” mandate, The Post has learned.

The EPA and the Elon Musk-led DOGE this week flagged 21 grants totaling $77.1 million previously awarded to 20 lefty nonprofits and universities, and the Trump administration will withhold $67.4 million in payments yet to be made, officials said.

The biggest loser is Vermont-based Institute of Sustainable Communities, which has yet to receive $12.4 million of the $16 million it was promised under two separate Biden-era grants to serve as a “National Environmental Justice Thriving Communities Technical Assistance Center.”
