Green menu makeover: Boost your sales with climate labelling

Carbon labels have become a hot topic in the food industry over the past years - with an increasing number of hospitality businesses including them in their sustainability action plans, and a multitude of researchers analyzing their effects on consumer behaviour.

Both experiments and real-life case studies have proved that sharing clear, contextualized carbon labels can have significant effects on the conscious or unconscious choices consumers make when buying food. 

In this article we’ll dig into the effects of carbon labels on consumer behavior and, most importantly, why food businesses should care if they want to boost sales while meeting their climate targets.

The Psychology of Carbon Labels

According to a Deloitte study, 39% of consumers are trying to conduct a more sustainable lifestyle by reducing their meat and animal products consumption. However, there is still a large portion of them who are uninformed or reluctant to change their food habits. 

In this scenario, carbon labels are proven to be among the most effective ways to nudge diners towards climate friendlier options. By implementing a climate smart menu design including carbon labeling, you and your team have the power in your hands to spread awareness and leverage psychology to encourage sustainable eating through your menu.



As a matter of fact, a recent study by researchers at the University of Würzburg showed how - when labels indicating emissions in kg CO2e are included for each dish on a menu - there can be a decrease in high-emission and an increase in low-emission dish choices. When participants in the study were given menus including carbon labels, the emissions associated with their dish choices were on average 13.5% lower per dish compared to when no carbon labeling was used.




How does carbon labeling affect consumer behavior?

Carbon labels intervene as a key predictor in climate-friendly food choices, educating diners on how their behaviors actually make an impact on the environment. In short, they help customers understand that there is a direct relationship between their food choices and GHG emissions contributing to climate change.

A European survey by IPSOS on behalf of Yara provided some significant data on consumers’ sustainable food preferences:  





Why should food businesses care?

By now you know that implementing carbon labels has a positive impact on the planet, but what about your business? 

Once again, recent data shows how labeling can actually boost your profit significantly by engaging environmentally-concerned customers:
