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.

Future-proofing in a decarbonizing market | April 15, 2026

This webinar covers the EPA’s move to rescind the 2009 greenhouse gas endangerment finding and repeal federal vehicle emissions standards. Speakers explain that the change weakens the basis for federal climate regulation under the Clean Air Act but note that litigation is already underway and the regulatory outlook remains uncertain.

The panel also stresses that major compliance obligations remain at the state and international levels. Expanding IFRS and EU disclosure frameworks continue to increase expectations around climate, sustainability, and supply-chain reporting, requiring organizations to take a broader multi-regime compliance approach.
 

 

Key topics

  • The EPA’s rescission of the greenhouse gas endangerment finding reshapes federal climate regulatory authority
  • Repeal of federal vehicle GHG standards does not eliminate legal or compliance risk
  • Litigation will play a central role in determining the durability of these regulatory changes
  • State, international, and industry specific greenhouse gas obligations remain in force
  • Climate and sustainability disclosures are expanding under IFRS and EU frameworks, increasing compliance complexity

Leaf micro

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.
