Oxford UniversityEnvironmental Impact Labelling

Insight

To reach net-zero, we need to know the impact of the foods we eat.

Although food production is responsible for a third of all human-induced greenhouse gas emissions, we tend to underestimate this impact at the checkout.

Labelling for price and nutritional content is standard across most grocery foods and products but making an informed choice about which are better for the environment is challenging.

The impact labelling design system can be applied across the consumer-facing food ecosystem, from physical packaging in-store to scanning food delivery apps or reading a menu in a restaurant.

The impact score encompasses a more extensive story on our choices by going beyond greenhouse gas emissions to include insight into a product’s effects on biodiversity, pesticide toxicity and water usage. This will result in a holistic snapshot of a product’s impact across its life cycle.

Oxford University senior researcher in human behaviour, Brian Cook, says most labels only tell one side of a much wider problem: “Carbon is just one part of the issue and well-meaning consumers who buy low-carbon labelled food might unwittingly find they’ve bought a product that instead impacts biodiversity loss or pollutes local water streams.”

Impact

Changing the way people eat at scale.

After an initial online study, the impact labelling framework and design system are being trialled in more than a dozen cafeterias across the UK.

From here, the hope is to bring the solution to supermarkets and other food outlets at scale to give customers more transparency on the environmental impact of their food choices and give the planet its best shot at a net-positive future.
