State AGs, U.S. Chamber, and Home Builders Support APGA’s Furnace Rule Challenge

By Renée Lani posted 04-18-2024 02:42 PM


On April 16, a number of different parties submitted amici briefs to the U.S. Court of Appeals for the D.C. Circuit in support of APGA’s legal challenge of the Department of Energy’s (DOE) final efficiency standard for non-weatherized residential furnaces, also known as the Furnace Rule.

Recall that APGA is jointly challenging DOE’s final Furnace Rule with the American Gas Association, National Propane Gas Association, and others. Consolidated with this challenge are also challenges to DOE’s final commercial water heating equipment efficiency standard and the agency’s withdrawal of the “interpretive rule,” which would have ensured consumer access to certain appliance technology. Read more about the legal challenge here.

These amici are critical in demonstrating the importance and breadth of our legal challenge. They are in support of our initial brief, which was submitted last week.  The next step is for DOE to submit it’s brief, which will happen in June.

The amicus brief from the state attorneys general is available here.

The brief from the Chamber is available here.

The brief from the home builders associations is available here.
