This paper reports on an in-depth study of refrigeration in the UK food chain. It identifies the greenhouse gas impacts of the ‘cold chain’ and discusses some of the technological options for reducing these. The main thrust of the paper is to explore the social, technological and economic factors which have given rise to what must now be regarded as a potentially problematic ‘refrigeration dependence’ in the food chain. We explore the historical roots of this dependency and discuss some of its key features. In particular we show how interactions between refrigeration technologies, packaging, transport, food product innovations and marketing have combined to help create cultural norms and practices which are now highly energydependent. Reversing this trend is likely to be far from easy. While energy efficiency measures and novel technologies are essential, they do not tackle the underlying structural need for refrigeration – the kinds of foods we eat and the way we manage our lives that renders refrigeration essential. ‘Defrosting’ our increasing addiction to the cold chain is likely to require significant changes in where and how we grow and transport food, in where and how we shop for it, and in how and when we cook it. We highlight in particular the potential to reduce refrigeration needs along the supply chain by reducing meat and dairy consumption, by more frequent local shopping, and by a shift towards ‘robust’ seasonal foods.
