Morrisons Tests Raising Freezer Temperatures to Cut Energy Costs and Emissions

morrisons tests raising freezer temperatures to cut energy costs and emissions business manchester

Morrisons is trialling a new way to save energy and reduce costs. It involves raising the temperature of its freezers by 3°C.

This change targets cutting energy consumption and lowering carbon emissions, a crucial step for sustainability.

A Bold Move in the Retail Industry

Morrisons is the first UK supermarket to deviate from the frozen food temperature standard set nearly a century ago. By increasing freezer temperatures from -18°C to -15°C, the retailer aims to cut energy bills and reduce its carbon footprint.

Geographical Spread of the Trial

The heat difference might seem minor, but it can make a significant impact on energy saving and efficiency. It’s a small step with potentially huge benefits.

Support from Major Players

This collaboration indicates strong industry support for innovative energy-saving methods.

Research Backs Up the Initiative

Carbon emissions could be reduced, equivalent to removing 3.8 million cars from the road. That’s a big deal for environmental efforts.

Long-Term Savings and Efficiency

This is promising for consumers and the company alike.

Morrisons’ Carbon Goals

Corporate services director Ruth McDonald said, “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.”

Industry Praise and Future Implications

CEO of Nomad Foods, Stefan Descheemaeker, added, “We know from our study that increasing the temperature at which we store frozen food can significantly reduce energy consumption and carbon emissions. Establishing an end-to-end frozen industry alliance to put our findings into action will be the key to unlocking widespread change.”

Conclusion of the Trial

The results from this trial could revolutionise energy consumption and carbon emission strategies in the retail sector.


Raising freezer temperatures seems like a minor change, but it holds significant potential. Morrisons’ trial, supported by industry leaders, could pave the way for substantial energy savings and emission reductions.

If successful, this initiative might set a new standard in the retail and frozen food industry, aligning with global sustainability goals.
