HFC regulation
The United States continues to legislate on HFCs. India, El Salvador and Serbia ratify the Kigali Amendment.
US to ban high-GWP refrigerants
A rule proposal by the US Environmental Protection Agency (EPA) provides that all high-GWP HFCs, including R134a, R404A and R410A, will be banned in most new refrigeration equipment...
Reducing the environmental impact of ultra-low temperature refrigeration systems
Ultra-low temperature (ULT) refrigeration systems often use very high-GWP HFCs. Yet, ULT systems are excluded from the scope of the regulations aimed at phasing-down HFCs. An IJR paper reviews the most promising...
Latest news about regulation in Europe
