storagetemperature is for producers to adjust their products with a longershelf life and new storage conditions and for retailers to agree tobuy these products and store them suitably.There is a general lack of data on the ability of food wasteprevention measures, including reduced storage temperature, toreduce food waste. Among the few previous studies examiningwaste prevention measures in supermarkets, two (Salhofer et al.,2008; Schneider, 2013) actually investigated donation to charities,which according to Papargyropoulou et al. (2014) is a separate issueand less favourable than actual prevention. True prevention, wherethe inflow of food is reduced, is described by Gentil et al. (2011) asa measure that reduces waste by reducing food production. Theproblem with that study is that it simply assumed a reduction of20% and did not specify how this reduction could be achieved.The objective of the present study was therefore to theoreticallyevaluate the potential cost and potential savings in food waste insupermarkets on reducing storage temperature in the food sup-ply chain. This was done by examining the relationships between:shelf life and food waste, storage temperature and shelf life, andstorage temperature and energy consumption. The overall aim ofthe study was to provide better data on measures to prevent foodwaste in supermarkets and thereby reduce the financial losses andthe greenhouse gas emissions.
