A left-wing organization accused of potentially violating antitrust law is quietly influencing the Biden administration’s push to enact expansive green energy policies, records show.

Ceres, a Boston-based environmental charity accepting large checks from undisclosed sources, says it works through “powerful networks and global collaborations of investors, companies, and nonprofits,” to support federal rules taking aim at the fossil fuels industry. That nonprofit group, which faced a subpoena in June from the House Judiciary Committee over whether it unlawfully facilitated collusion with major corporations, has spent more than $1 million on lobbying in recent years, all while working to shape a new climate disclosure proposal that energy groups argue is unpopular and a free-market overreach, according to documents reviewed by the Washington Examiner.
