Shift consumer social norms
Behavioural science tells us that increased knowledge of an issue alone does not necessarily translate into changed behaviour. What successful initiatives like the UK’s ‘Love Food, Hate Waste’ campaign have shown is that you must give people information and make it easy for them to change their behaviour.
That’s why ‘Love Food, Hate Waste’ ran advertisements to raise awareness and worked with retailers to get rid of offers such as ‘buy one get one free’ that encourage over-buying as well as to print food storage information on food packaging, making it easier for people to waste less food.
What’s needed is for norms in high-income countries and cities everywhere to shift so that wasting food becomes unacceptable.
