Maryland’s highest court has dismissed efforts by local governments to obtain damages from major energy companies for climate change-related harm. The ruling underscores the challenges faced by municipalities seeking to leverage state law against entities accused of contributing to environmental degradation.
This legal battle dates back to 2018, initiated by the city of Baltimore, which pursued claims against several energy giants. The claims were based on allegations that these companies’ long-standing activities significantly contributed to adverse climate effects impacting the city. Similar lawsuits were filed by Anne Arundel County and the city of Annapolis. Procedural wrangling over jurisdiction and venue ultimately brought the case to Maryland’s Supreme Court for a consolidated decision.
The court ruled that the local government claims, which included assertions of public nuisance, trespass, and failure to warn under state law, are preempted by federal law. Specifically, the court cited federal common law regarding interstate pollution and legislative frameworks such as the Clean Air Act. The court found that allowing state-level tort claims to proceed would disrupt the comprehensive regulatory scheme managed at the federal level for controlling greenhouse gases.
Even beyond preemption issues, the court expressed skepticism about the viability of the claims on other legal grounds. One significant barrier is the challenge in proving causation—demonstrating a direct link between the energy companies’ actions and localized climate damages that the plaintiffs are claiming. This aligns with broader legal trends where courts are cautious about tackling climate accountability within state courts, often stressing the complex, global nature of emissions and their effects.
This prevailing judicial caution is evident in similar cases across the United States, reflecting an ongoing struggle among municipalities striving to hold corporations accountable within the constraints of existing legal frameworks.
The decision represents a significant hurdle for state and local governments aiming to recover costs associated with addressing climate impacts. It adds to a body of case law that delineates the limitations of state court jurisdiction in matters involving global emissions, reinforcing the complex interaction between state claims and federal environmental policies.
