Director of Law & Policy, Environmental Integrity Project
Following Princeton and the University of Chicago Law School, David began practicing law at Paul, Weiss, Rifkind, Wharton & Garrison. Eventually tiring of litigation where the result was a wire transfer from Entity A to Entity B, in the early 1990’s David began his environmental law career at the Massachusetts Attorney General’s Office. Since then, he has litigated dozens of cases under all of the major environmental statutes including, as Sierra Club’s Chief Climate Counsel, initiating and managing Massachusetts v. EPA. Most recently, he has been busy challenging FERC’s permitting of natural gas pipelines and LNG export terminals. Apart from litigation, David has helped lead efforts on both greenhouse gas regulation and global warming legislation (and may be the only person ever invited to testify by both Barbara Boxer and James Inhofe).
He has drafted a range of federal climate legislation, advised states as to their greenhouse gas regulatory authority (and for many years has represented environmental groups defending state GHG regulations from dormant Commerce Clause challenges). David has designed and taught courses on “Environmental Litigation” at Georgetown University Law Center and “Environmental Law and Science” at the William and Mary Law School/Virginia Institute of Marine Science.
