A WWF spokesperson said: “We are a science-led organisation and on reviewing drafts of the report, we concluded that it did not meet our rigorous standards. The decision not to proceed with this report was not connected to any individual case study within it or our relationships with partners.
“We are deeply concerned by the devastating impact that pollution is having on the UK’s rivers, particularly the Wye, and have taken the government to court over its failure to act on river pollution. We continue to work to drive action to tackle the food system’s impacts on the environment, both in the UK and overseas.”
A Tesco spokesperson said: “This report was not part of our work with WWF and we were not involved in its development, nor any decisions about publishing it. The work of our partnership with WWF was aimed at tackling the biggest environmental impacts of our food system, including helping to protect water quality and biodiversity in supply chains.
“We’re committed to playing our part in protecting the River Wye, alongside other actors across the food industry, and have worked closely with local stakeholders since 2019 to tackle water pollution in the area.
“We’re also providing multi-year funding for a number of water catchment projects.”
