Morrisons raises freezer temperatures to cut emissions

British supermarket giant Morrisons has become the first UK retailer to join the ‘Move to -15°C’ coalition.


After signing the coalition’s letter of intent, Morrisons has increased the temperature in freezers in ten of its stores by three degrees.


Recent academic studies have shown that an increase of three degrees in freezer temperatures across the supply chain could 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 could result in potential savings equivalent to 8.6% of the UK's energy consumption, with a carbon emissions reduction that is equivalent to taking 3.8 million cars off the road.


For Morrisons, the carbon savings will boost its ambitions to achieve net zero carbon emissions from its own operations by 2035, with the significant cost savings enabling the supermarket to cut, hold or promote prices in its 500 supermarkets and 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.”


She continued: “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, added: “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.”


In a similar stance, in November last year, ice cream giant Unilever shared reformulation patents to combat freezer emissions in the ice cream sector. Providing access to these patents enables manufacturers to reformulate products that remain stable at a warmer freezer temperature of -12°C, a departure from the current standard of -18°C.
