Whether it concerns waste disposal, air emissions, underground storage tanks or other potential environmental law issues, companies are increasingly at risk for criminal penalties and civil damages awards arising from environmental issues. Quinn Emanuel brings a broad range of experience to address the unique problems companies face in environmental litigation.

Our lawyers have extensive experience in both civil and criminal environmental litigation matters. On the civil side, at the trial court level, Quinn Emanuel has successfully defended clients in matters ranging from nuclear waste disposal and the operation of industrial facilities and landfills to oil spills and soil and groundwater contamination. We have also assisted clients in defending against mass tort and class action claims based on a wide variety of environmental issues, as well as obtaining insurance coverage to pay for remediating contamination.

Quinn Emanuel also has an unparalleled record of success on appeal in environmental litigation. We have secured victories for clients before the Supreme Court, as well as the Courts of Appeals for the D.C., Second, and Ninth Circuits.

No other firm brings the depth of skills and knowledge that Quinn Emanuel does.


Recent Representations


  • Quinn Emanuel achieved a significant victory for its client Hyundai by successfully petitioning the Ninth Circuit en banc to overturn an unfavorable ruling by the initial panel. Quinn Emanuel represented Hyundai in multi-district class action litigation that was resolved at the district court through a class settlement. After a Ninth Circuit panel issued a decision overturning the district court’s approval of the class settlement, we successfully petitioned the Ninth Circuit for rehearing en banc. The en banc court affirmed the district court’s approval of the settlement allowing the nationwide resolution to move forward.
  • Quinn Emanuel represented the National Resources Defense Council and the Public Utility Law Project in filing an amicus brief in an action where a group of landlords challenged the New York City Water Board’s ability to set rates for water usage. The plaintiffs advanced a theory, adopted by a lower court, that would potentially hamstring the Water Board’s authority to set rates in ways that would reduce the burden on low-income households, incentivize water conservation, and prevent stormwater runoff (an emerging and important environmental issue in urban areas nationwide). The New York Court of Appeals adopted the argument advanced by Quinn Emanuel and the amici (and neither of the parties), ruling that the Water Board had acted within its authority, and preserving the Water Board’s authority to promote environmental issues going forward.
  • We successfully represented Entergy Corporation before the Vermont Supreme Court, obtaining dismissal of an original complaint seeking a shutdown of the Vermont Yankee Nuclear Power Station.  The Vermont Supreme Court held that no equitable grounds for relief existed.  We continue to represent Entergy in administrative proceedings in Vermont seeking a new state license for operation of the plant.  We also represent Entergy on matters involving federal preemption both in an appeal before the Second Circuit and in the U.S. District Court for the District of Vermont. 
  • We won an 8-1 victory for Shell Oil in the U.S. Supreme Court in Burlington Northern & Santa Fe Railway v. United States, which greatly limited “arranger” liability under CERCLA and held that Shell could not be held liable as an arranger for shipping useful chemicals.  The case also greatly clarified the standards for apportionment in CERCLA suits.
  • We represented the Alliance of Automobile Manufacturers in one of the highest-stakes appellate and environmental litigation matters in years.  At issue was whether nationwide greenhouse gas emission standards for automobiles, on which our client had already relied in constructing their 2012 model year fleet, would survive a challenge from a host of states and other industry groups in the U.S. Court of Appeals for the D.C. Circuit Court.  We helped the Alliance navigate a gigantic administrative record and ensured that no matter the outcome, the Alliance’s interests would be protected and the nation’s car manufacturers would continue to operate without interruption.
  • We obtained a significant victory in the Ninth Circuit for Shell Offshore Inc. and Shell Gulf of Mexico Inc. in a decision denying petitions for review challenging the Bureau of Ocean Energy Management’s approval of Shell Offshore Inc.’s Revised Camden Bay Exploration Plan under the Outer Continental Shelf Lands Act and holding that the agency was entitled to significant deference when interpreting the Act, interpreting its own regulations, and making certain technical and scientific assessments.  (This was our second win for Shell on such a petition; we obtained a similar win as to an earlier exploration plan in 2010.  The Court also issued an unpublished memorandum opinion denying petitions for review of the agency’s approval of Shell Gulf of Mexico Inc.’s Revised Chukchi Sea Exploration Plan.)
  • We represented the Alliance of Automobile Manufacturers in appeals before both the Second and the Ninth Circuits, in which we argued that federal fuel economy laws preempted state authority to regulate greenhouse gas emissions.  Seeking to overturn district court judgments in Vermont and California, we argued that federal law commits the task of  balancing fuel conservation against the economic impact on the auto industry to the federal government, not the states.  The appeals were ultimately mooted by new federal legislation that raised federal fuel economy standards.


  • We represented Entergy in seeking Vermont regulatory approval of a first-of-its-kind transaction in which an already-shutdown nuclear plant would be sold by a utility operator to a decommissioning schedule. The regulatory proceeding involved numerous rounds of written testimony, discovery, depositions, a settlement with certain parties (including the key Vermont agencies), and finally an evidentiary hearing before the Vermont Public Utility Commission.  The Commission issued its decision granting approval on December 6, 2018.
  • We represented OBOT, a real estate developer.  OBOT entered into a Development Agreement with the City of Oakland. The Agreement permitted OBOT to build a marine terminal to handle bulk commodities for export by cargo ship.  This type of agreement shields a developer from later-enacted regulations.  The city passed legislation proscribing coal from being handled at the terminal.  After a trial, the federal district court ruled that the city breached the Development Agreement because this later enacted legislation was not justified by a health and safety exception in the Development Agreement. The court enjoined enforced of the legislation against OBOT.
  • Since 2010, we have represented SEACOR and its subsidiaries with respect to thousands of claims relating to the DEEPWATER HORIZON oil spill. In addition, we have been named defense liaison counsel and appointed to the Defense Steering Committee. In 2014, in a significant victory for ORM and NRC, we won the fight to use a Lone Pine-type approach to force Plaintiffs to come forward with specific disclosures clarifying the basis for the claims asserted against them. Following receipt and analysis of Plaintiffs’ disclosures, in February 2016, the Court granted ORM and NRC’s motion for summary judgment on derivative immunity and implied conflict pre-emption grounds. The upshot was a dramatic victory: dismissal of over 20,000 claims asserting, among other things, exposure to dispersant during the cleanup, carving out only 11 claims for further proceedings.  This decision is significant because the Court found that private parties with no contractual relationship to the federal government can and will share in the government’s immunity in connection with their response actions where such actions were undertaken consistent with the government’s instructions. At the time, there were no other reported cases extending derivative immunity in this manner. Following this victory, we filed renewed motions for summary judgment as to the 11 remaining cases, which the Court granted in August.  We have thus successfully defeated all personal injury and exposure-based claims asserted against ORM and NRC in the MDL.  In addition, we won a Fifth Circuit appeal involving our prior summary judgment win in a personal injury action against SEACOR and its vessel. 
  • We represented Koch Industries’ entities in a number of lawsuits relating to the handling of petroleum coke and coal at transfer terminals in Chicago.  Quinn Emanuel defeated the Illinois Environmental Protection Agency's petition for emergency rulemaking before the Illinois Pollution Control Board, preventing the implementation of "emergency" regulations applicable to Koch’s operations.  Quinn Emanuel was lead counsel during a 1-week trial against the IEPA, after having been brought on to the case the weekend before the trial began.  In a 50 page opinion, the IPCB made findings in favor of Koch on every issue.  In addition, a class action lawsuit filed against Koch, as well as two separate lawsuits brought by Illinois Attorney General Lisa Madigan in Illinois state court, concluded in very favorable settlements for our client, which were largely attributable to our development of expert testimony to defend Koch’s operations.  Further, in the face of debilitating regulations proposed by the City of Chicago, Quinn Emanuel worked with Koch to present its opposition to the regulations.  In direct response, the City adopted many of Koch’s proposals in its final regulations.
  • We are representing AEP Generating Company (“AEPG”) and Indiana Michigan Power Company (“I&M”) in a $1.4 billion breach of contract and indemnification case brought by a series of trusts on behalf of corporate investors.  The case, Wilmington Trust Co. et al. v. AEP Generating Co. et al., (filed July 26, 2013 in the S.D.N.Y), concerns the operation of a coal-fired power plant located in Rockport, Indiana, which was sold to plaintiffs in 1989 in a sales/leaseback transaction.  After successfully moving to transfer the case from the Southern District of New York to Ohio, we obtained dismissal of the majority of plaintiffs’ claims.  Plaintiffs subsequently withdrew their remaining claims with prejudice and appealed to the Sixth Circuit.  On appeal, the Sixth Circuit affirmed in part and reversed in part the district court’s dismissal, and the case was remanded for further proceedings.
  • We represented Mitsui Chemicals Agro, Inc., in a case in California superior court in which a number of environmental groups challenged the validity of the State’s approval of new uses of our client’s neonicotinoid pesticide.  Following briefing and oral argument at a merits hearing, the superior court judge granted a complete judgment in favor of our client.
  • In a case the New York Times called “the most ambitious environmental lawsuit ever,” we helped secure a complete dismissal with prejudice that was subsequently affirmed on  March 3, 2017 by the US Court of Appeals for the Fifth Circuit.  The headline-making complaint named our clients Koch Industries, Inc. and Koch Exploration Company, LLC, and nearly a hundred other oil and gas companies, and claimed that oil and gas activities destroyed Louisiana’s coastline.  The Board alleged that, as a result, it faced increasing storm surge risk and flood protection costs, and sought damages from the defendants to pay for the restoration of the coastline, an effort it claimed would cost approximately $50 billion.  The case was the subject of extensive national and local press coverage as it touched on national issues like the Keystone Pipeline debate and the federal government’s role in encouraging oil and gas exploration, and hot button local issues such as wetland loss and hurricane protection.
  • We represent affiliates of Koch Industries in defense of class actions and governmental environmental lawsuits relating to the storage of petroleum coke, fugitive dust emissions, state and municipal regulatory challenges.

  • We represent Invista in a putative class action brought by property owners and citizens under the Resource Conservation and Recovery Act alleging groundwater and surface water contamination purportedly released through historical operations spanning over 50 years at a multi-purpose industrial facility, including manufacture of polyester and other polymers.  This multi-defendant case requires sophisticated groundwater modeling and chemical fate and transport expertise.
