DuPont™ Opteon™ YF, hydrofluoro-olefin (HFO-1234yf), will meet the European Union’s 2011 Mobile Air Conditioning (MAC) Directive to replace hydrofluorocarbon (HFC) 134a in MAC systems. This will result in significant reduction of the total environmental footprint associated with automotive air conditioning systems, including indirect emissions due to energy efficiency.

Opteon™ YF offers:

  • Lower lifetime greenhouse gas emissions than HFC-134a or CO2
  • Atmospheric lifetime of 11 days 
  • Comparable cooling efficiency to HFC-134a in all regions
