The PROTECT USA Act of 2025 aims to shield U.S. companies critical to national interests from foreign sustainability regulations, particularly those imposed by the European Union. The legislation seeks to ensure that these companies can operate and compete globally without the constraints of foreign laws that could impede their activities. Central to the Act is a prohibition against U.S. entities that are vital to national interests from complying with foreign sustainability due diligence regulations. This includes requirements for assessing and reporting environmental and social impacts.
