A pioneer of environmental litigation, Matt has been involved in many of the nation’s most important environmental cases for over 25 years. His 13-year lawsuit against more than a dozen oil companies for polluting New Hampshire groundwater resulted in the largest verdict in state history and Matt’s recognition as a 2013 Massachusetts Lawyer of the Year. His groundbreaking work with a group of eight state attorneys general and the City of New York in taking on the nation’s largest coal-burning electric utilities launched the first climate change tort case in 2004.
Matt has represented Vermont in litigation against 3M and Du Pont and for pollution of the state’s land and waters with PFAS—“forever chemicals.” He also has represented New Hampshire in litigation against Monsanto for pollution of state waters with PCBs and the State of New Jersey in litigation against Sherwin Williams for leaving a toxic legacy behind when it closed shop on the largest paint manufacturing facility in the world.
Matt has defended Greenpeace U.S.A.’s right to protest Shell’s Arctic drilling and obtained a dismissal of all criminal charges against climate protesters Ken Ward and Jay O’Hara in the Lobster Boat Blockade case. He also represented the Sierra Club, the Natural Resources Defense Council, and the Environmental Defense Fund against the automobile industry in cases that upheld state greenhouse gas laws in California, Vermont, and Rhode Island.
Prior to entering private practice, Matt served as an assistant county prosecutor in Burlington, Vermont. He is the recipient of the national Scribes Award for excellence in legal writing and the Fred G. Leebron Prize for constitutional writing. Matt is a frequent speaker at law schools and bar association events and regularly appears in national news stories. Before attending law school, Matt worked as a river guide on raft trips in the western U.S. and studied environmental science at Cornell University’s SUNY College of Agriculture and Life Sciences. He is the host of the Mother Earth Podcast.
