Pound for pound, HFCs are one of the most potent sources of climate pollution
Sustainable Business Virtual Trade ShowFor nearly a decade, ORNL’s Brian Fricke has investigated alternative refrigerants with low global warming potential for use in building equipment, such as commercial supermarket coolers and heating, air conditioning, and refrigeration systems.

This regulation helps reduce demand for HFCs to keep pace with reductions in HFC supply, as prescribed by the AIM Act. It gives clarity to manufacturers and consumers as to what alternatives should be expected, and by when. These transitions will avoid HFC emissions of up to 876 million metric tons of CO2 equivalent cumulatively through 2050 , beyond what is being saved by implementing the AIM Act’s HFC supply phasedown.
In some cases, the EPA’s new regulation will require states to update building codes to permit the use of climate-friendlier refrigerant alternatives, such as those that are forthcoming for air-conditioning and heat pump products. Today’s regulation signals in no uncertain terms that it’s now time to act on code changes.
In addition, under the proposed rule, any HFCs used in new supermarket systems, refrigerated transportation vehicles, and more must use reclaimed refrigerant. This type of approach will dramatically bolster demand for reclaimed HFCs — helping to improve the economics of refrigerant recycling — while further pushing companies to transition away from HFCs altogether.

US expels two Russian diplomats to retaliate for the expulsion of two American diplomats from MoscowThe Biden administration has ordered two Russian diplomats expelled from the United States in retaliation for the expulsion of two U.S. diplomats from Moscow last month. The State Department says it took the action in response to Russia declaring the two American diplomats persona non grata because of contacts with a Russian national who had once worked for the now-closed U.S. consulate in Russia’s far-eastern city of Vladivostok and was arrested this year. Spokesman Matthew Miller said: “The department will not tolerate the Russian government’s pattern of harassment of our diplomats.' The expulsions come at a time of animosity over the war in Ukraine and as diplomatic relations have plummeted to their worst level since the Cold War.
