A monolithic approach of gathering data simply on ‘food waste’ is not particularly helpful. However, the limited data suggest that food losses are much higher at the immediate post-harvest stages in developing countries. For affluent economies, post-consumer food waste accounts for the greatest overall losses (Parfitt et al., It has been estimated that the amount of food wasted per year in UK households is 25% (by weight) of that purchased, which is only the food wasted in the home. Of this in the UK, bread is the largest contributor to food waste, 32% of all bread purchased is dumped5. The further along the supply chain from the point of harvest at which a food product is wasted, the greater the carbon intensity of the wastage since the harvesting, transportation and processing accumulates additional GHGs along the supply chain.
