Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, how much food waste was generated by UK households by (a) tonnage and (b) amount of greenhouse gas emission in each year since 2010.

Periodic estimates of UK household food waste levels are undertaken by the Waste and Resources Action Programme (WRAP) with government funding:

• 2007 – 8.1 million tonnes
• 2015 – 7.1 million tonnes
• 2018 – 6.6 million tonnes

The next estimate reporting year is 2022/23.

WRAP have not estimated the greenhouse gas (GHG) emissions associated with only household food waste. They have estimated that food waste from manufacturing, retail, hospitality and food service and households together in 2018 was associated with approximately 36 million tonnes of GHG emissions each year.
