Key Strategies

Hannaford is taking several actions to manage refrigerant in its stores to improve its
environmental sustainability and save money.

Transitioning to environmentally friendlier refrigerants

To meet its sustainability goals, Hannaford emphasizes piloting new refrigeration and
technologies that rely on refrigerants with lower-global warming potentials (GWPs). In 2013,
Hannaford opened the first transcritical carbon dioxide (CQpVonly grocery store in the United
States in Turner, Maine, to learn more about the benefits and challenges of using a low-GWP,
high-pressure refrigerant. In 2016, Hannaford undertook the first transcritical CO? retrofit
project in the United States at its store in Raymond, N.H. More recently, Hannaford became
one of the first U.S. grocers to use the same system in a refrigerated warehouse. This
warehouse represents one of the world's largest refrigerated spaces to use a transcritical
system.

Managing Refrigerant to Protect the Environment

GREENCHILL

^"eFRlGERATlONP^

Many of the roughly 38,000 U.S. food retailers1 use
refrigerants that can deplete the ozone layer,
contribute to climate change, or do both when
emitted. As part of the U.S. Environmental
Protection Agency's (EPA's) GreenChill Partnership,
food retailers across the country are taking action
to prevent and reduce refrigerant leaks, reduce the
amount of refrigerant their systems use, and
transition to environmentally friendlier refrigerants.
These actions help protect the environment and
reduce operations and maintenance costs.

Hannaford Supermarkets is committed to reducing
its impact on the environment. Environmentally
friendlier refrigerants and leak reduction are key
strategies for achieving this objective. Hannaford
joined the GreenChill Partnership as a founding
Partner in 2007. This document highlights several of
the company's refrigerant management achievements.

Preventing and reducing refrigerant leaks

One of the primary benefits of CO2 is that it has one of the lowest GWPs of any refrigerant, so
any leaks from the system have much lower environmental impacts. In addition, Hannaford has
implemented new hand-held leak detection instruments to ensure leaks are caught and
addressed more quickly.

Achievements

Since joining the Partnership, Hannaford's efforts to manage refrigerant emissions have earned
the retailer recognition from GreenChill, its peers, and the industry as a whole. Hannaford has:

Reduced its company-wide refrigerant emissions rate by approximately 21 percent and
maintains a rate well below the GreenChill Partnership average; and
Reduced its refrigerant emissions rate per store by more than 15 percent.

The GreenChill Partnership

EPA's GreenChill Corporate Emissions Reduction Program is a voluntary partnership with food
retailers, refrigeration system manufacturers, and refrigerant manufacturers to reduce
refrigerant emissions and decrease Partners' impact on the ozone layer and climate change.
GreenChill Food Retail Partners commit to reducing their corporate-wide refrigerant emissions
by annually setting reduction goals, measuring corporate stocks and emissions, and reporting
their data to EPA. Learn more about the GreenChill Partnership and the benefits of joining.
