EPA revises Technology Transitions Rule: retail food and cold storage GWP deadlines shift to 2032 amid tightening HFC supply

The revised rule permits HFC-based equipment with GWP below 1,400 in retail food and cold storage through 2032, while the AIM Act phasedown will cut U.S. HFC production and consumption to 70% of baseline by 2029 and 85% by 2036. EPA analysis projects that HFC demand will exceed available allocations starting in 2029, and international experience shows legacy HFC prices rose over 1,000% in Europe and nearly tripled in Australia after quota reductions.

Australian Industry Proposes Phased GWP Limits for New Refrigeration and HVAC Equipment to Government

Refrigerants Australia and AREMA have submitted a draft GWP limits proposal to the Australian government, proposing 2030 as the key effective date for most equipment categories. Compared with the EU F-gas Regulation, the proposed pathway is more gradual, particularly in the commercial refrigeration segment.

EPEE Report: Extending F-gas Life Cycles Cuts PFAS Emissions 39% at a Fraction of the Cost

EPEE's new Executive Report, based on an independent ERM socio-economic assessment, identifies strengthening leak management and extending refrigerant service life within the existing EU F-gas Regulation as the most cost-effective pathway to cut PFAS emissions by 39% at a cost of €4.6 billion (2030–2050), compared with over €35 billion for more restrictive options.

SEAC to Complete PFAS Restrictions Assessment by End of 2026: What It Means for HFO 1234yf

The SEAC committee at ECHA is expected to publish its final opinion on PFAS in late 2026 to early 2027. RAC has already identified PFAS as a risk across the entire EU, while SEAC's draft supports restrictions with targeted exceptions rather than a total ban. For the refrigeration sector, the critical question is the future of refrigerant HFO 1234yf.

NIST review traces why F-gases dominated refrigeration and what the shift to alternatives demands of system design

A 2026 review by NIST researcher Mark McLinden in the International Journal of Refrigeration examines the thermodynamic rationale behind the adoption of fluorinated gases and the engineering challenges that will accompany their phase-out. The paper argues that upcoming F-gas restrictions will reverse the traditional design approach: systems must be built around the properties of the chosen working fluid rather than the other way around.

ChemSec: Single-Phase Liquid Cooling for Data Centers Already Works Without PFAS; Two-Phase Alternatives Still in Development

The ChemSec report, with technical support from Fraunhofer IZM (October 2026), systematizes PFAS-free alternatives for electronics cooling. Single-phase liquid systems — both immersion and direct-to-chip — already function without fluorinated heat-transfer fluids. Two-phase solutions, where the fluid evaporates during heat removal, remain in the pre-commercial stage; ChemSec questions the 13.5-year grace period proposed by the EU for restricting PFAS in two-phase immersion cooling.

Solstice to Sample Next-Generation Non-PFAS Foam Blowing Agent in Early 2027

Solstice Advanced Materials will begin sampling a developmental foam blowing agent with selected global customers in early 2027. The candidate is designed to deliver low GWP, nonflammability, and approximately zero ODP while not being classified as PFAS. Target applications include spray polyurethane foam, appliance insulation, and rigid foam products.
