Climate Change

Companies seeking clarity on ever-changing climate change rules and concurrent renewable energy options regularly turn to Arnold & Porter for guidance. We have extensive experience providing regulatory and compliance counseling, participating in rulemaking activities, providing representation in government and citizen enforcement actions, and defending some of the most significant climate change-related litigation matters. We appear regularly before U.S. EPA, the various EPA regional offices, and the California Air Resources Board. More broadly, our climate change practice extends to renewable energy and renewable fuel standards, carbon trading, GHG life cycle analysis, environmental assessment of climate impacts under NEPA, state and local climate regulations, climate litigation, green real estate, and fuel efficiency laws and regulations.

  • Insights and Experience: Our team includes former EPA and DOJ lawyers with decades of Clean Air Act experience.

  • Broad Industry Coverage: We represent clients in the automotive, engine, railroad, fuel, electric power, stored energy, and chemical industries across all aspects of the federal Clean Air Act, as well as various state programs, particularly California.

  • Carbon Capture Use and Storage: Our team is at the forefront of CCUS, advising clients on regulatory and liability considerations, as well as performing comprehensive assessments, of potential onshore and off-shore CCUS projects.
