  • Other Notes
    • Starting in January 2011, all new vehicle types must have an air conditioning refrigerant with a global warming potential GWP below 150. From 2017 on, this will apply to all new vehicles. This is based on the MAC Directive 2006/40/EG, passed in July 2006. Solstice yf refrigerant can be used in in Europe, Japan, Korea and the U.S. Under the ECE Agreement, Solstice yf refrigerant is also approved in Germany. APPROVALS: Solstice yf refrigerant is registered under the EU chemical regulation REACH, and is included in the U.S. E.P.A.'s SNAP Program Significant New Alternatives Policy. With this program, the EPA evaluates new and improved substances that replace ozone-depleting substances.
