Petition for review filed.
Environmental Defense Fund and Environmental Integrity Project filed a petition for review in the D.C. Circuit Court of Appeals challenging EPA’s interim final rule “Extending the Reporting Deadline Under the Greenhouse Gas Reporting Rule for Reporting Year 2025 to March 10, 2027.” EPA published the interim final rule on October 14, 2026. EPA previously extended the reporting deadline from March 31, 2026 to October 30, 2026 and issued a proposed rule in September 2025 that proposed that no industries would need to submit annual greenhouse gas reports for calendar year 2025.
