Study Highlights Misconceptions in Food’s Environmental Impact and Need for Labels

A new study highlights misconceptions in judging food's environmental impact, revealing a need for clear impact labels.
Most people get food’s environmental impact completely wrong, study finds

The way we perceive the environmental impact of our food choices might be more flawed than we think, according to a recent study. The research indicates a gap in understanding that highlights the potential benefits of introducing clear environmental impact labels on food products.

Misjudging Food’s Environmental Impact

In a study conducted by the University of Nottingham’s School of Psychology, 168 UK participants were asked to categorize supermarket foods based on their perceived environmental impact. The findings, published in the Journal of Cleaner Production, revealed widespread misconceptions about which foods are environmentally friendly or harmful.

Understanding Food’s Environmental Footprint

Food production significantly contributes to environmental issues such as greenhouse gas emissions and biodiversity loss. Understanding public perception of food’s environmental impact is crucial for promoting sustainable eating habits.

Researchers use a life cycle assessment to measure a food’s environmental impact, evaluating factors like greenhouse gas emissions, land use, and water use from production to disposal.

Exploring Perceptions of Grocery Store Foods

This study, backed by the UKRI’s Smart Data Research UK, is unique in its scope, assessing how people view the environmental impact of a broad spectrum of grocery items. Participants were shown scientific estimates and asked to compare these with their expectations.

Common Misconceptions Unveiled

The research identified two main criteria people use to judge environmental impact: whether a food is animal-based or plant-based, and its level of processing. Generally, participants believed meat, dairy, and processed foods have a higher environmental impact.

Contrary to these beliefs, many overestimated the impact of processed foods while underestimating water-intensive products like nuts. They were also surprised by the significant environmental difference between beef and other meats such as chicken.

The Case for Environmental Impact Labels

Lead author Daniel Fletcher, a postdoctoral researcher, explained: “We designed an online task to engage people with the topic and provide an interactive and visual way of investigating their understanding of the environmental impact of food. We found participants would be willing to change their purchasing behavior based on this task, reporting intentions to decrease (or increase) their future consumption of products for which they were surprised by how high (or low) the scientifically estimated environmental impact was.”

Fletcher noted the difficulty participants had in comparing the impact of animal-based and processed foods, suggesting that environmental impact labels with a single overall grade could simplify these decisions for consumers.

Co-author Professor Alexa Spence added: “The environmental impact data on food products is opening up new avenues for this research and this is the first study to look at this against a wide range of everyday products and examine what people’s perceptions of these are. What was clear from the study is that there are a lot of misconceptions around this which really supports the need for environmental impact labeling which would help people to be more informed to make sustainable food choices.”
