3. 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 % = about 1000 lbs. of refrigerant emitted PER SUPERMARKET per year)

4. GreenChill’s Purpose
EPA cooperative alliance with the supermarket industry
Promotes the adoption of advanced refrigeration technologies, strategies, and practices
Reduce charges & emissions of ozone-depleting substances (potent greenhouse gases)
Help protect the ozone layer and protect against global warming
Let me take a moment to explain the term “cooperative alliance”
There are 2 ways EPA achieves environmental improvements
The regulatory way and through voluntary partnerships, which is another name for a cooperative alliance.
Cooperative means that we work together with you. We don’t tell partners what to do; partners tell us what they need and I tell partners what EPA needs, and we cooperate to meet both needs.
It is an alliance because I run GreenChill but so do its partners. All the achievements I am going to speak about later are due to GreenChill’s partners, and there is no way that EPA would have taken on any of these topics if it weren’t for the partners.
You all know much about the regulatory side of what EPA does, and Dave Godwin is speaking after me on that subject.
GreenChill is a voluntary partnership. EPA decided to work in partnership with the supermarket industry to cut the environmental impact from refrigerants because EPA felt that the willingness and desire was there on the part of the supermarket industry.
Especially with a new administration coming soon, it is very important that GreenChill can continue to increase the number of its food retail partners to demonstrate that the voluntary way is working.
Through GreenChill EPA seeks to reduce refrigerant charges and emissions, which is good for the environment and good for your bottom line. We do this by promoting advanced refrigeration technologies, strategies, and practices. That means we promote distributed systems and secondary loop systems, but we are also in favor of “advanced” DX systems that reduce charges and emissions. We are in favor of good data management; we are in favor of leak alert systems; we are in favor of service tech training, we are in favor of CO2 systems. We are in favor of anything that reduces charges and emissions.
Because that’s what we need to do to repair the ozone layer and fight global warming.

5. Why Adv. Refrigeration Tech.?
Montreal Protocol’s goal is ozone layer recovery – reduces ozone-depleting substances (CFCs & HCFCs)
Substitute refrigerants (HFCs) are ozone-safe, 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
The Strat Prot Division’s mission is to repair and protect the ozone layer
Theoretically, we could all pat ourselves on the back if you move from R-22 that depletes the ozone layer to a refrigerant that doesn’t.
However the refrigerants that are being used as substitutes for R-22 are potent greenhouse gases.
So why in the world would we pat ourselves on the back if all we are doing is moving you from harming the ozone layer to higher global warming impacts?
The answer is that we aren’t - we are trying to get you out of this never ending cycle of you switching from refrigerant to refrigerant.
Reduce your charges and reduce your leaks because what does not enter the atmosphere cannot harm the atmosphere.

6. Benefits of Joining GreenChill
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
Better strategic planning
Better awareness among consumers for the good things you are doing - consumers want to do business with companies that care about the environment.
Improve your bottom line by reducing leaks and charges.
Let me just talk a little more about the value of having a friendly face at the EPA - GreenChill does not offer you regulatory relief - so if you illegally vent refrigerant you don’t get a pass because you are a GreenChill Partner.
But I have been able to straighten out situations that resulted from poor communication between food retail partners and enforcement people, and it can be helpful just to be able to call me if you don’t understand something. My Partners can and do call me with questions that they feel more comfortable asking me, and if I don’t know the answers, I find them out, anonymously, and help in any way that I can.
I am a resource that EPA has provided to you food retailers,so take advantage of it.

7. 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
If you join GreenChill you get all the listed benefits, and we ask only 1 thing from you: that you bring the desire to reduce your emissions.
You don’t have to change technologies. You don’t have to retrofit. You don’t have to stop using R-22.
You can have an exemplary refrigeration management system at your company or you can have an abysmal one.
We work with you to establish a baseline measurement of your refrigerant stocks and emissions,, using data you already have because the regulatory side of EPA requires it.
Then you set an emissions reduction goal and try to achieve it.
Nothing happens to you if you don’t achieve it- you just don’t get an award.
We realize that everyone is at a different stage in terms of their refrigeration management, so everyone’s reduction goal is different.
We ask that you have a plan in place to achieve that goal.
That’s it.

8. GreenChill and Small Retailers
Requirements are the same
Track your stocks and emissions
Reduce emissions
Benefits are also the same
Greater need for information?
Fewer resources?
Greater need for benchmarking?
There seems to be a misconception that GreenChill is only relevant to large food retailers.
The requirements are the same whether you own a single store or a couple thousand.
The only thing different may be the level of resources a small store has for refrigeration management and the access to information that a small store has, but that is more reason to join GreenChill…it should not be a disincentive.

I’d like to spend some time on GreenChill’s first year achievements.
The launch was a little over 9 months ago, but our partners have achieved so much!

10. First Year Achievements GreenChill Launch
Official launch end Nov. 2007
10 founding partners
Food Lion Giant Eagle
Hannaford Harris Teeter
Publix Whole Foods
Hill Phoenix Kysor Warren
DuPont Honeywell
EPA launched GreenChill towards the end of last year with 10 founding partners.
We’ve expanded the program to 31 partners.

11. First Year Achievements GreenChill Supermarket Partners
We have 22 supermarket partners.
4 systems manufacturers
And 5 chemical companies

12. First Year Achievements ART Systems Manufacturers
After GreenChill was launched last year, I received several hundred s and calls from component manufacturers. Our supermarket partners became very concerned very fast that GreenChill was going to lose its focus and be done before it really even got started
We decided to limit equipment manufacturing partners to those who manufacture entire advanced technology systems.
Our theory is that the systems manufacturers can work together with all the different types of component manufacturers, and GreenChill goals of leak tightness and smaller charges will trickle into the component manufacturers. I know that is less than ideal.
I am in the process right now of trying to figure out how to channel the enthusiasm brought to the table by component manufacturers. One things is for sure - you can’t talk about leaks without talking about components. I understand that, but I haven’t been able to figure out a way to take the next step without being overrun.
As with any small organization, I have to make sure that we grow in a way that adds value to the partnership, rather than growing in a way that overextends us and interferes with meeting our objectives.

13. First Year Achievements Chemical Manufacturing Partners

14. First Year Achievements GreenChill Supermarket Partners
5824 stores (17% of total)*
In 46 of 50 states, plus DC
$115+ billion in annual sales**
So I think we are off to a good start!
*35,000 U.S. supermarkets – FMI
***Does not include Hannaford and Price Chopper sales (part of larger holding companies)

15. First Year Achievements Supermarket Data Reporting
Partner Corporate Emissions Rates
Partner Average = 13.7% (Industry Average = 23.5%)
GreenChill partners saved
30 ODP tons
Refrigerant greenhouse gas emissions equal to 2,500,000 metric tons of CO2 (same as 500,000 passenger cars)
Important to point out that GreenChill is not just for food retailers with exemplary emissions rates. We have partners who are just average - which means that some of their stores are worse than average, some are better.
I hear from prospective partners “we’re not quite ready - we’re still making improvements”- it’s not about your corporate emissions level. It’s about making a commitment to do something to lower those emissions. The only reason to not join GreenCHillis if your corporate emissions rate is 0. Even then, why not join anyway for all the reasons I listed before - plus you will win all the awards.
Speaking of awards, it is my distinct pleasure today to give an environmental achievement award to the GreenChill Partner with the best emissions rate. I said “the partner,” but we have an enviable situation in that we have 2 best partners. They are within hundredths of percentage points away from each other, so rather than split hairs we decided it was a great thing to be able to give out 2 awards. Would Cliff Timko of Giant Eagle and Michal Shepard of Harris Teeter please come up here?
Giant Eagle and Harris Teeter are not just GreenChill’s leaders in terms of emissions rates. To lead is not just to be the best - to lead is to share and enable others to follow in your footsteps. I was told a year ago when I joined EPA that food retailers won’t share information - well, just one example Cliff and Mike agreed to hold a webinar for our other partners to share information on how they got down to a 10% emissions rate.
To lead is to keep setting challenging goals, and Harris Teeter and Giant Eagle have set among the most challenging goals in the partnership. I am proud to give them this award

16. First Year Achievements Benchmarking to Measure Progress
Compare leak rates to previous years
Compare leak rates to GreenChill average
Compare leak rates to competitors
Compare leak rates to nationwide average
Allows you to learn where you stand, are you doing as well as you thought you were?
Allows you to learn what is possible
Allows you to determine where you want to go
Benchmarking is absolutely key to strategic planning

17. First Year Achievements In-Store Marketing Ideas
Supermarkets told us that they want to do more to communicate their membership in GreenChill to their consumers, so we designed a set of in-store marketing ideas that are available for our food retail partners. They range from “A GreenChill Zone” as pictured here, to a GreenChill design that partners can incorporate into their non-disposable shopping bags, to cooler stickers and shelf stickers.

One project I am very proud of is our GreenChill’s Advanced Refrigeration System certification Program.
I am happy to announce it’s launch today.
If you have a food retail store that meets the level of refrigerant charge reductions and leak tightness in our standards, if you do not use any ozone depleting refrigerants, you will be awarded GreenChill’s silver or gold award for your advanced refrigeration system.
GreenChill is not wedded to any one type of advanced refrigeration system. We came up with our own criteria. You can have a DX system, and as long as you have reduced your charge and your leak rates to these levels, you may qualify.
We decided to develop this because existing standards and certification systems that we came across did not give enough credit to refrigerant management, even though refrigerants are the sole responsible activity for the industry’s effect on the ozone layer, and they are overproportional contributors to supermarkets’ impact on global warming.
Not giving proper credit for stores that are taking the lead in refrigerant management is perhaps encouraging stores to invest in environmental improvements that do not have as much impact on the environment as refrigerants.
So we decided to solve that problem. This is not just for GreenChill partners - though if you are making this kind of progress I don’t know why in the world you wouldn’t want to join the partnership.

29. First Year Achievements Information Sharing - Webinars
August 20: Leak Prevention & Maintenance
September 25: GreenChill Certification for ART in Food Retail Stores
October 14: Retrofit Guidelines
TBD: ART Energy Use
TBD: Installation Leak Tightness
I mentioned before that a benefit of belonging to GreenChill is the information sharing and the learning that results from that sharing of information.
We had our 1st webinar a couple weeks ago for our partners, and I’m told it was a great success.
Some of these are for partners only, for instance the one on leak prevention and maintenance, because of the semi-confidential nature of the information.
Others will be open to everyone, such as the next 2 that are upcoming.
Our goal is to have 1 a month.
We want GreenChill to offer food retailers value above and beyond publicity for your environmental leadership. Some companies believe “no publicity is good publicity” That’s fine, but there are other good reasons to join the partnership - and if you want me to, I’ll promise that the name of your company will never cross my lips except to add your name to the list of members.

Information that our food retail partners want to know too
Are you doing everything you can to ensure that the systems you deliver to food retailers is leak tight? How leak tight is it possible to get equipment? How do you even measure that? No universal standard - 100% leak tight as measured with nitrogen testing, or helium testing, or hydrogen testing? We have to develop a standard before we can start measuring.
Can you guarantee that your system is leak tight when it is installed? Traditionally, this has not been the realm of the systems manufacturers, but we are developing a system that creates accountability all the way to leak tight installation.
Which leads into the next slide.

34. GreenChill Projects 2008/2009 Service Tech / Contractor Certification
North American Technical Excellence (NATE) Exams
Commercial Refrigeration Service: 44% pass rate
Commercial Refrigeration Installation: 23% pass rate (Beta Test)
GreenChill/NATE project to improve service tech knowledge of environmental best practices in refrigeration service & installation
As a result of feedback from our partners, GC realized there was a missing link in terms of the types of stakeholders who worked with GreenChill.
We are just at the beginning of a new project with NATE to allow service technicians to obtain GreenChill certification, which will be proof to food retailers that these service techs know the best environmental practices related to refrigerant management.
We are also working with the Green Mechanical Council on several projects.
I’ll be able to report more on that next year.

You will hear from EPA later on when Dave Godwin gives you a regulatory overview that when EPA projects for R-22 demand in 2010, 2015, and 2020, they assume a certain level of recovery and reclamation.
R-22 users are not recovering and reclaiming at the rate that EPA estimates they can and should be.
GreenChill has plans to work with our chemical manufacturers to increase recovery and reclamation within the supermarket industry.
GreenChill is challenging our chemical manufacturing partners to provide more incentives for supermarkets to recover refrigerant and reclaim refrigerant.
How do we make sure that the recovery and reclamation process is proceeding according to the best environmental programs available.
We are just getting started on this, and I’m told this is another area where I’m going to run into all sorts of challenges. We’ll see. Recovered refrigerant is a valuable resource. Why give it to someone else if you are going to need it at another store in your group, and why pay someone to haul it away for you.
