We worked with WWF-UK on the data collection and analysis content for WWF’s What’s in Store for the Planet: The impact of UK shopping baskets on climate & nature – 2025, the fourth in a series of annual reports that measure the environmental impacts of UK baskets in the UK.
Each year, the WWF Basket report provides an update on how UK retailers are progressing against a goal set in 2021 of halving the environmental impact of UK shopping baskets by 2030. Seven out of ten reporting retailers have signed the WWF Retailers’ Commitment for Nature.
Our natural economy team has been working with WWF-UK to deliver the WWF Basket report over the last four years. In 2025, we collected data from ten of the UK’s top food retailers, representing over 90% of the UK’s grocery market, across seven areas: Climate, Agriculture, Marine, Diets, Food Waste, Packaging, and Deforestation and Conversion.
This year, the data showed that most retailers are continuing to make progress in some areas. For instance, retailers are making good progress on Scope 1 and 2 emissions reductions (12% closer to the target compared to last year). Our analysis also shows that regulations (such as extended producer responsibility) are a key driver for change, with packaging recyclability at high levels across all retailers.
Despite the challenges, data disclosure and quality have improved year-on-year for most areas, indicating that retailers are increasingly prioritising transparency of action, supported by improving data systems.
However, the findings revealed there is still room for improvement in many areas. Most retailers are lagging in their progress toward reducing Scope 3 emissions, and significant work remains to achieve food waste goals.
For each of the seven focus areas, the report also highlights specific actions for retailers and supply chains to advance progress. These range from increasing uptake of science-based targets within supply chains, to quantifying greenhouse gas emissions from packaging and developing actions to reduce them. The report also advocates government leadership, such as mandating food waste reporting and incorporating best practice food waste reduction into legislation.
