A new Biden administration rule aimed at reducing carbon emissions would give approval authority over large U.S. defense contracts to a little-known British environmentalist group that just incorporated two weeks ago.

Under the White House’s proposed rule change, a London-based group called the Science Based Targets Initiative that is funded by the Democratic Party’s main dark money network would be responsible for approving the carbon emissions reduction plans of large federal contractors.

The Science Based Targets Initiative (SBTi) is a fee-based service that helps companies set emissions reduction targets in line with the Paris Climate Agreement and verifies their progress. But its foreign status and murky financial background raise questions about the Biden administration’s decision to outsource its vetting process to the group. Critics say the proposal would give SBTi enormous veto power over American defense contracts and access to potentially sensitive data about U.S. military suppliers.
