Last month, the U.S. EPA repealed the 2009 greenhouse gas (GHG) Endangerment Finding, the legal basis for many federal climate regulations.
What this means in practice is still evolving:
• Federal GHG standards could change — depending on litigation outcomes
• States may step in with their own requirements
• Long-term planning for regulated facilities is now more uncertain
For now, most facilities should not assume compliance obligations disappear overnight.
