US State leadership is keeping the HFC transition on track, and keeping the U.S. in sync with the global phase-down now underway under the Kigali Amendment. This past month, Washington State’s HFC phase down passed the legislature and Governor Jay Inslee signed bill HB 1112. Meanwhile, Vermont has announced that they are intending to phase down HFC refrigerants as well through their new bill ‘S. 30.’ The bill passed the legislature and is expected to have a signature from the governor soon. This adds to the ever growing list of states that have chosen to regulate HFCs.
So far all of these state planned phase downs have been modeled after the original Environmental Protection Agency’s SNAP Rule 20 and 21 from 2015. Vermont and Washington, along with twenty-three other states, are part of what’s known as the United States Climate Alliance. This alliance was formed when the Trump Administration pulled the United States out of the Paris Climate Accord. The goal of the alliance is to create a coalition of states that work together to fight Climate Change and Global Warming. If the Federal Government isn’t going to do anything then the states will get it done and regulate HFCs themselves. The other states in the Climate Alliance are all expected to follow suit in the coming years.
The Federal Government’s positions on regulating HFCs has been confusing for the industry. The EPA’s SNAP Rule was thrown out by the courts. The Kigali Amendment went into effect at the beginning of this year but the United States never ratified the treaty. As more states join the phase down, manufacturing companies are going to be forced to move away from HFCs even without a Federal mandate. If enough states choose to regulate HFCs then manufacturers will either have to produce two different models,one for HFC states and one for non-HFC states, or the they will have to do a complete transition to lower GWP refrigerants.
The bottom line is that HFCs are going to be replaced by either natural refrigerants, hydrocarbons, or HFOs. If the U.S. government doesn’t ratify the Kigali amendment and/or the EPA doesn’t take charge of HFC’s, the U.S. may end up with a haphazard set of rules varying from state to state leading to even more refrigerant confusion.
