The United States is urging the European Union to further dilute two flagship sustainability laws that require large companies operating in the bloc to disclose environmental and social impacts across their supply chains. U.S. Ambassador to the EU Andrew Puzder said the EU had committed during July 2025 trade talks in Turnberry, Scotland, to ensure the Corporate Sustainability Due Diligence Directive and Corporate Sustainability Reporting Directive do not create undue barriers to EU-U.S. trade. Washington is also seeking changes to the Carbon Border Adjustment Mechanism, the EU levy on imports tied to carbon emissions standards. The push comes as U.S. and EU officials turn from tariff commitments agreed in July to non-tariff issues, with three sources expecting joint statements in the autumn on that part of the Turnberry agreement. Brussels has already softened some contested policies, including anti-deforestation and methane rules, and last year narrowed the scope of its corporate sustainability regime by limiting CSDDD to the largest companies, delaying compliance to mid-2029, and raising the CSRD employee threshold to more than 1,000 from more than 250. Several sources familiar with the EU position said the bloc is not planning further concessions on those measures.
