Local governments have several distinct options when climate impacts create public costs they attribute to oil and gas companies: pursue damages in court, adopt emissions rules within authority delegated by state law, and prepare for and adapt to local hazards. A lawsuit may seek compensation for asserted local costs, but it is not the same as regulating fossil-fuel production—and it cannot replace measures to protect residents and public assets. The legal reach of each option depends on state law, the facts, the requested relief, and federal-law challenges.
What can a city or county do?
The options are not interchangeable. A damages case asks a court to assign responsibility for alleged harm and award relief. A local emissions rule regulates activity within the government’s authority. Adaptation work reduces exposure to hazards regardless of whether a lawsuit succeeds.

| Route | What it may do | Important limits |
|---|---|---|
| State-law litigation | Seek compensation for specified public costs allegedly connected to climate impacts and company conduct. | Standing, causation, limitation periods, state tort law, jurisdiction, federal displacement or preemption, available remedies, and proof can all be disputed. |
| Local emissions rules | Set requirements for sources or activities within a city or county’s delegated authority, such as building emissions in New York City. | Local powers and state preemption rules vary. A decision interpreting New York statutes does not establish authority elsewhere. |
| Adaptation and resilience | Plan for hazards and reduce risks to residents and public assets. | Specific measures and funding depend on local hazards, engineering needs, authority, and budgets. |
| State action | Establish statewide policy through legislation or executive action, including state-led litigation or climate superfund laws. | Federal challenges may raise preemption and constitutional issues; a challenged law should not be described as finally upheld unless a court has ruled. |
What does a climate lawsuit against oil companies seek?
A local-government case may seek damages for public costs associated with climate-related harms. The allegations about a company’s knowledge, conduct, or causal responsibility are claims by plaintiffs unless a court has made findings on them. A damages claim is distinct from a request to regulate future emissions or fossil-fuel production.

The county says the suit does not ask a court to stop or regulate future fossil-fuel production in Colorado. That is the plaintiffs’ description of the requested relief, not a judicial finding about the merits or eventual effect of the case.
#1 Best Overall
For a local government considering litigation, the concrete record matters: which local harms are alleged, what public expenditures have been made or are expected, how the claimed costs are connected to the alleged conduct, and what remedy the government is asking a court to award. Causation and the proper scope of relief are among the issues that can make these cases difficult.
Why have courts reached different results?
Colorado: a preemption challenge did not end Boulder’s case
In May 2025, the Colorado Supreme Court concluded that federal law did not preempt Boulder’s state-law claims at the procedural stage before it, allowing the case to continue. The decision did not establish that the companies were liable. A ruling that a case may proceed past a particular challenge is not a decision after trial on responsibility or damages.
Maryland: local governments’ state-law claims were dismissed
On March 24, 2026, Maryland’s Supreme Court affirmed dismissal of state common-law claims brought by Baltimore, Annapolis, and Anne Arundel County against fossil-fuel companies. As reported by the Sabin Center for Climate Change Law, the court treated the alleged claims as involving interstate and international pollution, held that federal law displaced the state-law claims, and also identified deficiencies in several asserted tort theories. The ruling concerns Maryland claims and law; it is not a nationwide resolution of all local climate cases.

Together, the Colorado and Maryland decisions show why there is no single national answer to whether a local climate case can proceed. Outcomes can turn on the jurisdiction, claims, procedural posture, and the court’s view of federal law. They do not amount to a general finding that oil companies are liable for local climate costs.
Rank #3
Can a city regulate emissions locally?
Potentially, when state law gives it authority and no controlling state rule bars the measure. That authority question is separate from whether the city or county can recover damages from companies in court. Home-rule provisions, state statutes, and preemption doctrines differ among states.
New York City’s building-emissions law
In 2025, New York’s Court of Appeals held in Glen Oaks Village Owners, Inc. v. City of New York that the state Climate Leadership and Community Protection Act did not field-preempt the city’s Local Law 97. That local law requires greenhouse-gas reductions from large buildings. The court relied on the state act’s text and context, including provisions recognizing continued compliance with applicable local laws; it held, “We hold that the Climate Act does not preempt the field of regulating greenhouse gas emissions.”
The court described Local Law 97 as setting citywide greenhouse-gas reduction targets of 40% by 2030 and 80% by 2050, both relative to 2005 levels. Those figures describe New York City’s law as addressed in the 2025 decision, not a general requirement for other municipalities.

What federal challenges should officials watch?
The U.S. Department of Justice announced complaints challenging anticipated climate lawsuits in Hawaii and Michigan and climate superfund laws in New York and Vermont. DOJ alleged that the measures conflict with the Clean Air Act, raise foreign-affairs concerns, or violate constitutional limits. Those are the federal government’s allegations and requested relief, not court findings. DOJ described New York’s Climate Change Superfund Act as seeking $75 billion; that figure is not an award by a court.
Best Value
These challenges illustrate potential federal issues, but their effect depends on court decisions and the specific law or claim being challenged. A local government should distinguish a state-law tort suit from a state superfund statute and from a local emissions ordinance: they involve different legal authority, defendants, remedies, and risks.
What is the status of the Boulder case at the October 2026 cutoff?
The U.S. Supreme Court granted review on February 23, 2026. Its docket lists questions about federal preemption and whether the Court has statutory and Article III jurisdiction. Oral argument was scheduled for October 5, 2026. As of October 4, 2026, the argument had not yet occurred, so no outcome from it can be stated here.
How should local officials compare the options?
- Define the objective: Is the goal compensation for identified public costs, emissions control under local authority, protection from hazards, or a combination?
- Identify the legal authority: Check state and local law for the government’s power to sue, regulate the relevant activity, or undertake the planned measures.
- Document local effects: Maintain records of harms, public expenditures, and the evidence connecting alleged conduct to claimed costs. Evidence and causation will be contested in litigation.
- Specify the requested remedy: A request for damages is not automatically a request to control production or emissions. Describe the relief precisely and assess its legal implications.
- Assess the relevant forums and risks: Consider state tort law, jurisdiction, federal displacement or preemption, and any constitutional or foreign-affairs arguments raised in the particular dispute.
- Keep adaptation moving: Emergency preparedness and resilience planning address local exposure directly and should not depend on the timing or outcome of a lawsuit.
This is a U.S.-focused overview, not a state-by-state survey or legal advice for a particular city or county. The examples show distinct legal questions, not a guaranteed path to recovery or regulatory authority.
