Green. Chill Advanced Refrigeration Partnership EPA & the Supermarket Industry: Partners in Environmental Protection

Agenda Supermarket Refrigeration & the Environment Green. Chill Advanced Refrigeration Partnership Purpose Partner Benefits Supermarket Partner Responsibilities Small Businesses Achievements in 2007/2008 Ongoing Projects

Supermarket Refrigeration & the Environment R-22 is primary refrigerant Harms the ozone layer (ODP of. 055) Contributes to climate change (GWP of 1810) Phase-out in 2010 of R-22 production for new equipment; Limited production allowed until 2020 to service existing refrigeration equipment DX systems are the dominant technology Lg. refrigerant charges (ave. spmkt. = 4000 lbs. ) High leak rates (ave. 20 -25% = about 1000 lbs. of refrigerant emitted PER SUPERMARKET per year)

Green. Chill’s Purpose EPA cooperative alliance with the supermarket industry Promotes the adoption of advanced refrigeration technologies, strategies, and practices Reduce charges & emissions of ozonedepleting substances (potent greenhouse gases) Help protect the ozone layer and protect against global warming

Why Adv. Refrigeration Tech. ? Montreal Protocol’s goal is ozone layer recovery – reduces ozone-depleting substances (CFCs & HCFCs) Substitute refrigerants (HFCs) are ozonesafe, but they are greenhouse gases Leaking 1000 pounds of greenhouse gas instead of 1000 pounds of ozone-depleting gas is just substituting one environmental problem for another

Benefits of Joining Green. Chill Benchmarking to evaluate progress Recognition for actions beyond regulatory requirements Build brand equity Tools to attain corporate environmental stewardship and sustainability goals Prepare for HCFC phaseout and other deadlines Access to latest information on state-of-the-art refrigeration technologies, alternative refrigerants, and best practices Networking & information sharing among partners

Supermarket Partner Responsibilities Commit to using only non-ozone-depleting refrigerants in both newly constructed stores and major remodels Report a baseline of corporate-wide refrigerant stocks and emissions Commit to an annual emissions reduction goal Develop a corporate Refrigerant Management Plan and emissions reduction strategy Report annual aggregate corporate-wide refrigerant stock and emissions

Green. Chill and Small Retailers Requirements are the same Track your stocks and Reduce emissions Benefits emissions are also the same Greater need for information? Fewer resources? Greater need for benchmarking?
