US EPA considers R410A ban from 2025

United states: Business and environmental teams in the US are pushing for a ban on R410A in new domestic and professional air conditioning tools from January 1, 2025.

The proposals are contained in petitions prior to the United States Environmental Safety Company (EPA) which have been submitted less than the recently handed Intention Act to restrict the use of HFCs.

The EPA has granted, or partly granted, 11 petitions. Seven of these petitions relate particularly to the air conditioning and refrigeration field. 

Numerous of the petitions acquired and granted by the EPA have overlapping requests to limit HFCs in certain sectors. In several cases, the HFC limits, sectors coated, and changeover timelines are similar.

In common, the petitions request a 150 GWP limit threshold for most refrigeration which includes supermarkets and ice rinks, and a 750 GWP restrict for air conditioning.

The petitions mainly assist the SNAP Procedures 20 and 21, which ended up initially proposed by the EPA in 2014 but overturned in the US Court of Appeals in 2017. These proposals, which sought to prohibit the use of specified increased GWP refrigerants in particular apps, have been afterwards adopted by California and a quantity of other US states.

Granted petitions involve people symbolizing producers – the Air conditioning, Heating and Refrigeration Institute, and Association of Dwelling Equipment Companies – and the environmental teams – the Environmental Investigation Agency, Organic Means Protection Council and the Institute for Governance & Sustainable Enhancement.

In the air conditioning sector, this could see a ban on new tools with a GWP of 750 or greater for all domestic and commercial models from 2025, with an extension for VRF to January 1, 2026. For air conditioning chillers, the petitioners get in touch with for the ban to turn out to be productive from January 1, 2024.

This proposal would correctly ban R410A, thanks to its GWP of 2,088, leaving the flammable A2L refrigerants R32, with its GWP of 677, and R454B (GWP R466) as the key now offered professional possibilities, with flammable A3 propane in more compact methods. It may perhaps be no coincidence that the 750 GWP highest leaves the door open for Honeywell’s non-flammable A1 refrigerant R466A, with its GWP of 733, if or when it results in being commercially obtainable.

The chance of a 750 GWP most is also currently being regarded by the European Fee less than the recent revision of the European F-fuel regulation.

On the refrigeration front, the petitions also suggest bans on the use of refrigerants with a GWP of 150 or earlier mentioned in all new grocery store systems, cold storage warehouses, some industrial system refrigeration, and other stationary refrigeration tools on January 1 2023.

Stage down

The ultimate HFC stage down rule under the Goal Act, signed last month, establishes a in depth programme to cap and phase down the production and intake of HFCs in the US by 85% by 2036.

A important portion of the AIM Act authorises the EPA to limit the use of HFCs in sectors in which they are utilised, both absolutely, partially, or on a graduated agenda.

The EPA will now have two years to take into account these petitions and propose and finalise rule makings. Other petitions not nonetheless granted are however becoming considered.
