The U.S. Court of Appeals for the Seventh Circuit has upheld a lower court's decision to send back a climate change lawsuit filed by the City of Chicago against BP P.L.C. and other fossil fuel companies. This ruling, issued on July 15, 2026, affects the ongoing legal battles between cities and fossil fuel companies over climate change damages. The decision is significant as it clarifies the limits of federal jurisdiction in such environmental lawsuits.
The case, City of Chicago v. BP P.L.C., was initially filed in March 2024 in Illinois state court. Chicago's lawsuit targeted fourteen energy companies, claiming they misrepresented the effects of fossil fuel emissions on global warming. The city sought compensation for various harms attributed to climate change, including health issues, property damage, and environmental degradation. The defendants, including BP, sought to move the case to federal court, arguing it related to their work with the federal government under the federal officer removal statute.
The dispute centers on whether the defendants could successfully argue that their historical production of fossil fuels for the federal government justified the removal of the case to federal court. The defendants pointed to their past contracts and production efforts during World War II and the Cold War as grounds for this claim. However, the City of Chicago maintained that its allegations were based on state and local laws, not federal jurisdiction.
The case made its way to the Seventh Circuit after the district court remanded it back to state court, stating that the defendants' connection to federal duties was too tenuous to warrant federal jurisdiction. The appeals court affirmed this decision, emphasizing that the defendants' historical federal work did not relate closely enough to the claims made by Chicago.
In the ruling, Circuit Judge Taibleson stated, "The connection between the defendants’ production of fossil fuels to support mid-century war efforts and their alleged false advertising to consumers decades later is 'tenuous, remote, or peripheral.'" This statement highlights the court's view that the historical context of the defendants' federal work did not justify the removal of the case to federal court.
The appeals court also noted that the City of Chicago had explicitly disclaimed any injuries arising from the defendants' federal work. This disclaimer was significant in the court's analysis, as it clarified that the city's claims were based solely on the defendants' alleged misinformation and deceptive practices directed at consumers.
The ruling has broader implications for similar cases across the country. It reinforces a growing trend in which courts have rejected attempts by fossil fuel companies to remove climate change lawsuits from state to federal court. The Seventh Circuit's decision aligns with other recent rulings in various circuits, which have consistently found that such lawsuits do not sufficiently relate to federal duties to warrant removal.
As cities and states continue to pursue legal action against fossil fuel companies for climate-related damages, this ruling may serve as a precedent for future cases. It emphasizes the importance of clearly defining the basis for jurisdiction and the need for a direct connection between federal duties and the claims made in environmental lawsuits.
Looking ahead, it remains to be seen whether the defendants will attempt to appeal this ruling or if they will seek other legal strategies in response to Chicago's claims. The Seventh Circuit's decision does not preclude the possibility of future attempts to remove the case based on new developments or evidence. The legal landscape surrounding climate change litigation continues to evolve, and this ruling is a significant chapter in that ongoing story.
