Creating a sustainable shopping basket

With food production at the centre of many environmental issues, Tesco and WWF have come together to make it easier for everyone to access an affordable, healthy and sustainable diet. Through the partnership we aim to halve the environmental impact of the average UK shopping basket.

Making the average UK food shopping basket more sustainable requires action across various environmental impact areas. We have identified seven key areas to focus our efforts on, which have then been weighted based on a range of criteria.

  • Scope: environmental issues with a global impact are weighted higher than regional issues (climate change, large-scale deforestation)
  • Irreversibility and urgency: issues requiring urgent action to ensure impacts do not become irreversible are also weighted higher (climate change, loss of virgin forest habitat)
  • Direct impact: the more direct an environmental impact the higher the weighting (greenhouse gas emissions directly contribute to climate change, while packaging may, or may not, pollute the environment and oceans)
  • Governance: issues with the most effective governance are weighted lower

Based on these considerations, we have weighted the flagship issues as follows:

  Issue Weighting

1

Climate change

25%

2

Deforestation

20%

3 

Sustainable diets

15%

4

Sustainable agriculture

12%

5

Marine sustainability

10%

6

Food waste

10%

7

Packaging waste

8%

Each criteria will include a number of sub-metrics. For instance, sustainable agriculture will include the following:

  • % of farmers taking robust action to improve soil health (e.g. cover crops, low impact tillage;
  • % of farmers who are taking robust action to increase biodiversity and pollinators (e.g. wildflowers, hedgerows, Integrated Pest Management);
  • % of fresh produce from regions with sustainable water management;
  • % of key sourcing regions with clear plan to address agri-plastic pollution.
