About Environmental Litigation
Environmental litigation encompasses lawsuits arising from contamination of air, water, and soil; violations of environmental statutes and regulations; disputes over natural resource use and development; and claims for damages caused by pollution and exposure to hazardous substances. This area of law draws on a complex interplay of federal and state environmental statutes, common law tort principles, constitutional protections, and increasingly, international environmental agreements and climate science. Environmental litigation is unique in its technical complexity, the involvement of multiple parties and regulatory agencies, the enormous potential damages at stake, and the interplay between scientific evidence and legal standards.
Major categories of environmental litigation include enforcement actions brought by federal and state regulators against alleged violators; citizen suits authorized under the Clean Air Act, Clean Water Act, and other environmental statutes allowing private parties to enforce environmental laws; toxic tort claims by individuals harmed by exposure to pollutants; natural resource damage claims brought by government trustees to recover the cost of restoring natural resources injured by contamination; cost recovery and contribution actions under CERCLA among parties responsible for contaminated sites; and constitutional and administrative challenges to environmental regulations and permitting decisions.
Environmental litigation often involves cutting-edge scientific issues including epidemiology, toxicology, hydrology, atmospheric science, and ecology. Expert testimony is central to most environmental cases, and the battle of experts frequently determines outcomes. Cases can take years or even decades to resolve, involve thousands of parties, and result in verdicts and settlements reaching billions of dollars. The growing focus on climate change has introduced a new dimension of environmental litigation, with lawsuits seeking to hold fossil fuel companies liable for climate damages and challenges to government climate policies.
Why You Need an Environmental Litigation Attorney
Environmental litigation serves as a critical mechanism for enforcing environmental protections when regulatory agencies lack the resources or political will to act. Citizen suit provisions in environmental statutes empower communities to hold polluters accountable directly. For individuals and communities harmed by contamination, litigation may be the only avenue for obtaining compensation for health effects, property damage, and diminished quality of life. For businesses, environmental litigation represents both a significant risk and, when defending against unmeritorious claims, a necessary protection of legitimate interests. The outcomes of environmental litigation shape corporate behavior, influence regulatory policy, establish precedent for future cases, and determine who bears the cost of environmental cleanup and remediation.
Common Environmental Litigation Cases
CERCLA Cost Recovery and Contribution
Lawsuits among potentially responsible parties at contaminated sites to allocate cleanup costs. CERCLA imposes strict, joint and several, and retroactive liability, making these cases intensely litigated as parties seek to minimize their share of often enormous cleanup costs.
Citizen Suit Enforcement
Lawsuits filed by individuals, community groups, or environmental organizations to enforce compliance with environmental statutes when government agencies have not taken adequate enforcement action.
Natural Resource Damage Claims
Claims brought by federal, state, and tribal trustees to recover the cost of assessing and restoring natural resources injured by releases of hazardous substances or oil spills.
NEPA Challenges
Lawsuits challenging the adequacy of environmental impact statements and environmental assessments prepared by federal agencies for major projects, including infrastructure, energy development, and land management decisions.
Clean Water Act Discharge Litigation
Enforcement actions and citizen suits for unpermitted discharges of pollutants into waters of the United States, including stormwater violations, industrial discharges, and agricultural runoff.
Climate Change Litigation
A growing body of cases seeking to hold energy companies liable for climate change damages, challenging government climate policies, and enforcing climate commitments under constitutional and statutory theories.
Environmental Insurance Coverage Disputes
Litigation between policyholders and insurers over coverage for environmental cleanup costs, pollution liability claims, and regulatory defense costs under commercial general liability and environmental insurance policies.
Typical Environmental Litigation Case Timeline
Case Investigation and Assessment
3-12 monthsInvestigating the factual and scientific basis for claims or defenses, including site investigation, environmental sampling, document review, and identification of potentially responsible parties.
Pleadings and Early Motions
3-6 monthsFiling the complaint, answering, and resolving early motions including motions to dismiss, challenges to standing, and jurisdictional disputes. Environmental cases often involve complex multi-party pleading issues.
Discovery
1-3 yearsExtensive fact and expert discovery, including document production that may involve millions of pages, depositions of fact and expert witnesses, and site inspections. Environmental discovery is often the most time-consuming phase.
Expert Reports and Daubert Challenges
6-12 monthsExchange of expert reports on causation, damages, and scientific issues. Daubert motions challenging the admissibility of expert testimony under federal rules are critical in environmental cases.
Settlement Negotiations or Trial
6 months to several yearsMediation, settlement conferences, and direct negotiations. If settlement is not reached, trial on liability and damages. Multi-party environmental cases may require allocation proceedings among defendants.
Post-Judgment and Appeals
1-3 yearsEnforcement of judgments, implementation of remediation requirements, monitoring of compliance with consent decrees, and potential appellate proceedings.

- Property owners have the right to assert innocent landowner, bona fide prospective purchaser, and contiguous property owner defenses to CERCLA liability if they meet the statutory requirements.
- Communities have the right to participate in environmental decision-making through public comment periods, public hearings, and access to environmental information under EPCRA and state right-to-know laws.

What to Look for in an Environmental Litigation Attorney
Environmental litigation requires an attorney with both legal expertise and the ability to work with complex scientific and technical evidence. Look for an attorney with specific experience in the type of environmental claim involved, whether it is CERCLA liability, citizen suit enforcement, toxic tort defense, or regulatory challenges. The attorney should have experience working with environmental consultants, expert witnesses in fields such as toxicology, hydrogeology, and risk assessment, and understanding of remediation technologies. Trial experience is important because environmental cases that go to trial involve sophisticated evidentiary battles over causation, damages, and scientific methodology. For CERCLA cases, experience with potentially responsible party negotiations, consent decree drafting, and contribution actions is essential.
Questions to Ask Your Environmental Litigation Attorney

- 3Who are the other potentially responsible parties, and is there a basis for contribution or indemnification claims?
- 4What expert witnesses will be needed, and what are the key scientific and technical issues that will drive the outcome of the case?
- 5Is there insurance coverage for this environmental claim, and has proper notice been provided to all potentially applicable policies?
- 6Should we pursue settlement or prepare for trial, and what are the relative costs and risks of each approach?
Understanding Environmental Litigation Legal Costs
Environmental litigation is typically among the most expensive areas of legal practice due to the technical complexity, lengthy discovery periods, and need for multiple expert witnesses. Attorney hourly rates range from $350 to $800 or more for experienced environmental litigators. Total litigation costs for significant environmental cases routinely reach $500,000 to several million dollars per party. Expert witness costs alone can reach hundreds of thousands of dollars. For plaintiffs in toxic tort and citizen suit cases, contingency fee arrangements are common, with attorneys receiving 25-40% of any recovery. CERCLA and citizen suit statutes allow recovery of attorneys fees in certain circumstances. Some environmental insurance policies cover defense costs for pollution-related claims.
