Tesco to help customers visualise the environmental impact of their shopping

As part of its collaboration with WWF, Tesco has produced a new metric which enables customers to track the environmental impact of some of its most popular products.

The metric will track the environmental impact of 20 of Tesco’s most frequently sold own-brand items across seven issues: climate change; deforestation; sustainable diets; sustainable agriculture; marine impact; food waste and packaging waste.

Each of these impacts will be allocated a different weighting to give products an overall percentage score, with climate change given the highest (25%) weighting and packaging waste (8%) the lowest.

By early 2020, Tesco and WWF will have analysed data and produced an overall score for each of the 20 products, which include milk, eggs, fruit, vegetables, tinned tuna, snack foods and pre-prepared lines.

This information will enable the supermarket to set a date by which it believes its target of halving the impact of the average UK shopping basket can be reached. Tesco is hoping to deliver on this ambition by 2030 at the latest, by working with supply chains to combat issues such as deforestation, water mismanagement and soil degradation.

Tesco’s chief executive Dave Lewis said the firm’s work with WWF forms part of its mission to provide shoppers with “good quality, affordable food that is produced in a sustainable way”.

“Throughout our partnership, we’ll be carrying out industry-leading work to make food production more sustainable, including sourcing commodities like soy and palm oil from verified zero-deforestation areas, and improving soil health and water usage on farms in the UK,” Lewis said.  

“Working together, we can help to ensure the natural environment is protected for future generations.”

According to the Intergovernmental Panel on Climate Change (IPCC), humanity currently uses 72% of the world’s ice-free land surface, largely for the production of food and other raw materials. This land use currently accounts for almost one-quarter of man-made emissions on an annual basis, with livestock and agriculture-related deforestation two of the key contributors.
