LyondellBasell Industries N.V.

Environmental Matters

From time to time, we and our joint ventures receive notices or inquiries from government entities regarding alleged violations of environmental laws and regulations pertaining to, among other things, the disposal, emission and storage of chemical and petroleum substances, including hazardous wastes. U.S. Securities and Exchange Commission rules require disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions that we reasonably believe could exceed $300,000. The matters below are disclosed solely pursuant to that requirement and we do not believe that any of these proceedings will have a material impact on the Company’s Consolidated Financial Statements.

In April 2025, the State of Texas filed suit against Equistar Chemicals, LP, a subsidiary of LyondellBasell N.V., in Travis County District Court seeking civil penalties and injunctive relief for violations of the Texas Clean Air Act related to several alleged emission events between May 2018 and April 2021.

In May 2025, the Texas Commission on Environmental Quality issued a proposed Agreed Order to Equistar Chemicals, L.P., a subsidiary of LyondellBasell N.V., to resolve alleged air permitting exceedances at the La Porte Complex between 2020 and 2022.

Litigation and Other Matters

Information regarding our litigation and legal proceedings can be found in Note 11 to the Consolidated Financial Statements, which is incorporated into this Item 1 by reference.
