Environmental Assessment •  All Solstice® molecules and their intermediates have been subject to LCAs

by independent third parties -  Low embedded energy -  Water usage -  Effluents

•  Atmospheric Chemistry assessed by Prof Nielsen (U. of Copenhagen) and others including members of the UNEP Scientific Assessment Panel.

-  GWP = 1 or less -  No POCP impact

•  Assessed by US EPA (SNAP) and EU (REACH) -  SNAP approved -  No Use Restrictions under EU REACH

•  Fits Resource Efficiency Model -  High value promotes recovery, reclamation and re-use

•  Energy Efficiency drives Refrigerant Selection -  HFO blends designed to address specific thermodynamic ranges

HFOs Are An Excellent Solution

Conclusion • HFOs are a near drop-in, environmentally preferable alternative to

HFCs that meet / exceed global environmental imperatives. -  Global Warming Potential: Pure HFOs have GWPs that are 99.9% lower than

the products they replace. -  Efficiency: HFOs provide greater efficiency versus other ultra-low GWP

refrigerants. -  Availability: The versatility and availability of HFOs can help speed up the

implementation of lower GWP systems, particularly in developing countries at the start of their phase-out.

-  Ease of Implementation: For customers looking for simple, cost-effective solutions that do not require expensive new systems, HFOs offer a near drop-in solution.

•  There is no single solution for every refrigeration application, but every application can have a smart solution for both the environment and the user. -  HFOs deliver cooling performance and energy efficiency while driving down

GWP, and are an essential component of the future of refrigerants.
