EPA’s Endangerment Finding Rescission: Upcoming Programs

Webinars and invitation-only dinners on EPA authority, litigation outlook, and practical compliance planning.

About this series

EPA’s rescission of the greenhouse gas endangerment finding has introduced new uncertainty around federal greenhouse gas regulation, the scope of EPA authority under the Clean Air Act, and the litigation that may follow.

Our programs are designed for in-house counsel, sustainability leaders, and compliance teams and focus on what has changed, what remains in place, and where risk may shift next—including state and international obligations and private governance expectations.

For questions about how these developments affect your business or to discuss participation in upcoming programming, visit our Sustainability and EHS page or contact Jaime Novack.

State & International Climate Obligations in a Post Federal Framework

As EPA rolls back key federal greenhouse gas rules, many organizations are seeing heightened climate-related risk from stricter state, local, and international requirements. International climate agreements can also influence national obligations and enforcement priorities.

This webinar reviews emerging compliance pressures, enforcement trends, and practical steps for managing climate obligations in a post-federal framework. We will also discuss how international climate agreements may intersect with US regulatory approaches and related agency actions.

The discussion is designed to help in-house counsel and compliance leaders align internal policies with evolving state standards, cross-border requirements, and long-term climate obligations under both public law and private governance initiatives.

Roundtable discussion | February 25, 2026

This on-demand program explains EPA’s decision to rescind the 2009 greenhouse gas endangerment finding and roll back federal vehicle greenhouse gas standards—and why the change is a significant legal development across regulated sectors.

Speakers walk through the rule’s legal rationale, expected court challenges, and what the shift could mean for regulated industries, state climate programs, and international obligations. The discussion also covers practical considerations for climate-risk management and climate-related disclosures.
 

 

Key topics

  • Rescission of the 2009 endangerment finding: what the withdrawal means for vehicle standards, potential ripple effects for other sectors, and key areas to watch.
  • Clean Air Act authority: how EPA is interpreting its authority and how key definitions may shape future greenhouse gas regulation.
  • Key Supreme Court cases: implications of Massachusetts v. EPA, West Virginia v. EPA, and Loper Bright for the scope of regulation and the federal-state balance.
  • Current and future legal challenges: likely arguments, expected timelines, and how courts may approach questions of statutory interpretation and agency authority.
  • Impacts beyond vehicle standards: possible effects on power plants, oil and gas operations, aircraft engines, and interactions with state programs and compliance planning.
