New peer-reviewed research, commissioned by the Waste & Resources Action Programme (WRAP), shows that annual UK household food and drink waste has fallen by 1.1 million tonnes (13%) over a three year period (2006/7 and 2010) from 8.3 million tonnes to an estimated 7.2 million tonnes. Wrap's figures, based on data from 90 local authorities, indicate that the recession and falling incomes may have played a part in the food-waste reduction.
The report demonstrates that the environmental impact of avoidable household food waste is around 17 million tonnes of CO2e, and 4% of the UK total water footprint. The savings associated with the reduction in avoidable food waste amount to around 3.6 million tonnes of CO2e, and almost a billion litres of water a year.
According to the report, the associated reduction in food waste is broadly consistent with decreases in the quantity of food and drink purchased for consumption within the home. The decrease is also discussed in light of possible influences, including:
- Positive changes in practices and behaviours in the kitchen and whilst shopping, and changes to products and packaging, that can reduce food waste;
- Food price rises;
- Changes to income levels; and
- How waste is collected from homes.
