What does the topic mean?

Secure, available, economically just, affordable and healthy – a sustainable diet has a low impact on the environment, contributes to food security and enables current and future generations to live healthy lives.

Goal of the nudge

The best-before date (BBD) is not the same as the use-by date. The aim of our nudge is to prevent food waste caused by the misinterpretation of the best before date.

    Needs analysis

    • High consumption
      High consumption of limited resources in the production and transportation of food.
    • Rising prices
      Rising prices of staple foods disadvantage poorer countries.

    Cause analysis

    • Anchoring effect

      An assessment anchor is set by the BBD, which distorts the assessment of the food.

    • Precautionary principle

      One does not want to take the health risk.

    • Social norm

      What do those around me think of me when I consume expired products?

    • Convenience

      No time to deal with trying expired products.

Target Group

52% of all food waste in Germany occurs in private households. Shortly before consumption or during cooking, the behaviour of this target group should be changed.

Added value of the nudge

  • Save greenhouse gases

    Savings of 21.8 million metric tons of greenhouse gases in Germany

  • Create awareness

    Increased awareness of the meaning of the BBD

  • Saving resources

    Savings of two full shopping carts = 75 kg of food per person
