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.

South Sudan Ratifies Kigali Amendment, Becoming 176th Party with 80% HFC Reduction Obligation

South Sudan ratified the Kigali Amendment on 23 October 2026, becoming the 176th country to do so. As a Group 1, Article 5 party, it must freeze HFC production and cut HFC consumption by 80% by 2045, while also reducing HCFC use by 65% against its 2009–2010 baseline.

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.
