Energy, Environment and Natural Resources

With lawyers across the United States and in key international locations, our team handles high-stakes matters before the regulatory and enforcement agencies with energy and environmental oversight.

Our lawyers draw on a long history in environmental law, energy project financing and permitting, public land use, climate change policy, and environmental justice to solve complex challenges. Clients depend on our legal skill and insight from government service to achieve their objectives, and they also depend on our industry and technical understanding—we have represented entities from a wide range of industries, including oil and gas, renewable energy, gas and electric transmission and distribution, mining, recreation, aviation, defense, real estate, education, life sciences and pharmaceuticals, and financial services.

We help these clients to manage environmental enforcement and other litigation challenges; to develop and permit energy production, transmission, and generation projects in the renewable, oil and gas, and nuclear sectors; and to navigate an increasingly complex regulatory playing field, including on matters related to climate change and environmental justice. Our team, which includes former high-ranking officials at the US Interior and Defense Departments, and the US Justice Department’s Environment and Natural Resources Division, is well prepared to assist clients in government investigations and to respond to other facets of high-profile crises. 

Seamless Service. Clients depend on us to tackle complex disputes and policy challenges because we offer a comprehensive, integrated and efficient approach. Our environmental lawyers partner with trial and appellate teams if litigation cannot be negotiated or settled to an acceptable resolution. And with strong corporate, public policy and legislative practices, we bring a deep understanding of the business objectives and regulatory landscapes that drive clients’ decisions and shape their industries. Harnessing insights from across these disciplines, we develop comprehensive strategies that reflect clients’ budgets, needs and priorities.
