Supermarket Refrigeration, Carbon Emissions, Climate Change & A Poll!

How often do you walk into the fresh food section of your favourite (or not) supermarket and wish you had brought along a snowsuit or at least a jersey… More often than not my entrance to the refrigerated product section while grocery shopping makes me want to turn around and run. The refrigerated product section tends to be rather chilly…. maybe too chilly sometimes. I understand the need to ensure constant low temperatures in the food chain/ management process etc etc, however, one needs to consider the costs involved with maintaining low temperatures for such large open areas. This is particularly the case when the entire refrigerated food section of a shop is cooled and the fridges are door less. Surely the simple action of installing doors on supermarket fridges would reduce the need to cool entire sections of supermarkets while also reducing cooling costs and associated emissions?

Some interesting facts about supermarket refrigeration and emissions are;

  • Chemicals released by fridges account for 30% of British supermarkets’ direct emissions (www.gaurdian.co.uk)
  • There is concern about the use of damaging HFC (hydrofluorocarbon) gases as coolants which were introduced in the 1990s as a safer alternative to ozone-depleting chemicals such as CFCs (chlorofluorocarbons) and hydrochlorofluorocarbons (HCFCs). (www.chillingfacts.uk.org)
  • Supermarkets are the biggest industrial emitters of HFCs, which do not damage the ozone layer but have a high global warming potential.
  • One tonne of the widely used gas called R404a has a warming effect equal to 3,900 tonnes of CO2 over a 100-year period. (www.gaurdian.co.uk)

Issues such as financial costs, emissions and environmental costs all need to be considered and mitigated particularly now, due to the need to respond to the effects and impacts of resource scarcity, climate change and environmental degradation. Many supermarkets and refrigeration companies are working towards reducing the use of technology and substances that emit green house gasses. However, the move towards efficient, sustainable and climate friendly refrigeration solutions for supermarkets seems to be quite slow and I have been wondering why it is that most supermarkets still have open, door less fridges? I do realize that some supermarkets are actively (or in certain instances slowly) working towards using less harmful refrigeration systems is it not easier to simply place glass/ transparent doors on fridges in the interim? That way shoppers can see what is inside the fridge’s while the supermarket maintains appropriate temperatures and reduces cooling costs and emission. There is also the option of motion sensitive automatic doors on fridges? Are door less fridges not being used because:

  • Manufactures don’t make large fridges with doors?
  • Cost involved with doors on fridges?
  • Supermarkets are scared that consumers will buy less if they have to open a door? Or if there is a glass door between the food and the consumer? Supermarkets therefore opt to provide lazy shoppers with the easiest option?
  • Shoppers are perceived as being too lazy to open a door?
  • Germ transfer from door handles are seen as a problem?

So I thought it would be a good idea to see how many people think doors on supermarket fridges are a viable interim measure for supermarkets to adopt until we are able to have more efficient and sustainable cooling systems in all our supermarkets.

Please humor me and take this poll so that we are able to determine whether or not asking supermarkets to install doors on their fridges is a viable option!!
