^{Mobile Air Conditioning (MAC) Refrigerant Credit}

Honeywell is supportive of actions that will continue the transition to environmentally preferable alternatives to hydrofluorocarbons (HFCs). We commend the decision to preserve the Mobile Air Conditioning (MAC) refrigerant credit option in the SAFE Affordable Fuel-Efficient (SAFE) Vehicles Rule. The MAC credit option will help continue the transition to innovative refrigerants developed in the U.S. that will support local manufacturing and industry leadership. One of these refrigerants is Solstice® yf, which is currently installed used by over 90 million vehicles globally and is expected to grow to in more than 115 million vehicles globally.
