The U.S. on Friday threatened action against the EU unless Brussels reins in its environmental and human rights rules, which Washington says unfairly burden American companies.

Acknowledging Brussels had made “some positive reforms,” Washington said the EU had “failed to fully address U.S. concerns,” and that it “will take any actions necessary to address unreasonable burdens on U.S. commerce.”

U.S. Ambassador to the EU Andrew Puzder piled on the pressure Friday, writing on X that “now it’s time for the EU to deliver.” He pointed to commitments made under last year’s Turnberry trade deal to ensure U.S. businesses do not face “undue restrictions” on transatlantic trade due to Brussels' green regulations.
