A new study has revealed that the majority of supermarket products claiming to be 'natural' or 'sustainable' are using these terms primarily as marketing tools, with little to no substantive certification backing them up. Researchers from the University of Oxford and the University of Manchester analyzed hundreds of food and household items in major UK supermarkets and found that less than a third of such claims were supported by independent third-party certifications.
Misleading Claims Common
The study, published in the journal Nature Sustainability, examined over 2,000 products across seven supermarket chains. It found that terms like 'natural', 'sustainable', 'eco-friendly', and 'green' were used on packaging without clear definitions or verification. 'These terms are largely unregulated, allowing companies to make vague environmental and health claims that can mislead consumers,' said Dr. Emily Carter, lead author of the study.
Certification Gap
Only 28% of products with such claims had any form of third-party certification, such as the Rainforest Alliance or Fairtrade labels. The rest relied on self-declared statements or ambiguous wording. 'Consumers are increasingly looking to make ethical choices, but without proper regulation, these labels are little more than marketing hype,' added co-author Professor James Miller.
Consumer Confusion
The research also surveyed 1,000 shoppers, finding that 72% believed products labeled 'natural' were better for the environment, and 65% thought they were healthier. However, the study notes that many of these products contain synthetic ingredients or are produced with significant environmental impact. 'There is a clear disconnect between consumer perception and reality,' said Dr. Carter.
Call for Regulation
The researchers are calling for stricter regulation of environmental and health claims on food and household products. They suggest that the UK government should adopt a framework similar to the EU's upcoming 'Green Claims Directive', which would require companies to substantiate their claims with robust evidence. 'Without intervention, the market will continue to be flooded with meaningless terms that undermine genuine sustainability efforts,' said Professor Miller.
Supermarket representatives have responded by stating that they comply with current regulations and are committed to providing accurate information. However, the study highlights the need for clearer standards to help consumers make informed choices.
