Morrisons becomes the first UK retailer to take action with the “Move to -15°C” Coalition and commits to raise freezer temperatures in drive to net zero
Published:02 August 2024

- Moving frozen food temperatures from -18°C to -15°C saves significant amount of energy with no impact on food safety -

- The current industry standard (-18°C) was set almost 100 years and has not been updated since, despite improvements in refrigeration - 

Morrisons is pleased to be the first UK retailer to take action with the Move to -15°C Coalition and will take the first concrete step on 1st August 2024 by turning the freezers up in 10 stores by three degrees.

Recent comprehensive academic studies have shown that an increase of just three degrees in freezer temperatures across the supply chain will transform the global logistics landscape by cutting carbon emissions, saving energy and lowering costs.  Widespread global adoption of a change of just 3°C across the supply chain would mean potential savings equivalent to 8.6% of the UK's energy consumption, and reduce carbon emissions equivalent to taking 3.8 million cars off the road.

In signing the Move to -15°C coalition’s letter of intent, Morrisons is also committing to advocate through the UK supply chain for food producers, logistics operations and retailers to join the coalition.

For Morrisons, the carbon savings will be an important boost to its ambitions to achieve net zero carbon emissions from its own operations by 2035 and the significant cost savings will enable Morrisons to further cut, hold or promote prices in its c.500 supermarkets and c.1,600 convenience stores across the UK over the long term.

Ruth McDonald, Morrisons Group Corporate Services Director, said: “Industry standards today are based on safety, science or convenience.  The standard temperature for the storage and transport of frozen food today looks like it is simply a convention from nearly 100 years ago.

“We now have vastly better freezers and modern technology and monitoring that gives us a precise picture of frozen food temperatures throughout the supply chain.  We applaud the Move to -15°C movement for their original thinking and willingness to challenge a long-accepted standard and in doing so identify a significant opportunity for positive progress for both the environment and the food industry.

“So on behalf of our customers, our carbon commitments and the planet we are enthusiastically embracing the opportunity and putting together a concrete plan and timetable to increase the freezer temperatures across our stores and frozen supply chain by 3°C.  As we execute our plan, we will be encouraging our suppliers and partners to do the same.”

Thomas Eskesen, Chairman of the Move to -15°C Coalition, said: “We are delighted to welcome Morrisons to our Coalition, and are excited that they are taking action. In order for us to be successful with making the change to -15°C, it is essential that we have representatives and support from every stage of the frozen food supply chain, so to have a large UK retailer like Morrisons on board is an important step forward for us.

“By raising the temperature of its freezers in 10 of its stores across the UK, Morrisons is demonstrating that change is possible, and we know that this seemingly small change can lead to a significant, positive, environmental impact.”
