In August 2018 Ethical Consumer viewed WWF-UK's shop website for its supply chain management policy. The following statement was found under the FAQs, " What are WWF’s eco-criteria?", "We strive to offer gold standard sustainable products, and request all our suppliers meet our extensive eco-criteria. For example, this covers paper and wood from FSC sources, no one use plastics and organic cotton for textiles." It was noted that its clothing range used organic and Fairtrade cotton.
In 2017 WWF-UK had an income of over £60m, therefore it was expected to have a publicly available policy which stated what criteria suppliers must meet in order to be included on the website. In addition it was also expected to have a policy stating what workers' rights were guaranteed within its supply chain.
Ethical Consumer also viewed WWF-UK's Modern Slavery statement which stated "We are introducing a supplier code of conduct to be used initially in respect of suppliers we deem to be working in areas of higher risk in respect of modern slavery."
WWF-UK was contacted to provide further information however no response was received.
Without a policy stating how it managed its supply chain it received Ethical Consumer's worst rating for supply chain management.
