Carbon footprint labels on menus encourage diners to decide on extra climate-friendly meals, research finds

Itemizing the carbon footprint of dishes on menus encourages diners to decide on extra climate-friendly meals, researchers have discovered.

A research by the College of Würzburg in Germany discovered eating places offering colour-coded details about the greenhouse gas emissions of each meal can nudge clients to go for the greener possibility.

Dr Benedikt Seger, who led the research, stated: “The members in our research selected the veggie burger extra typically when it was introduced as the usual possibility on the menu and never the meat burger, as is often the case.”

A complete of 265 volunteers had been introduced with 9 menus with details about greenhouse fuel emissions. They had been informed, for instance, {that a} couscous salad could possibly be ordered with beef (excessive emission), rooster (medium emission), or falafel (low emission).

The research discovered members selected extra climate-friendly dishes when labels had been accessible, resulting in a mean of 200 grams much less carbon per meal.

“These are outstanding outcomes when you think about that on no account all the members within the research gave up meat dishes and different CO2-intensive meals due to the defaults or labels,” Dr Seger added.

The researchers stated their findings confirmed individuals had been keen to contemplate the urgent drawback of the local weather disaster even in small on a regular basis choices akin to ordering a meal.

Dr Seger, a psychologist, stated: “That is on no account self-evident once we contemplate that in a restaurant we benefit from the meals, the ambiance and the get-together with others, so we don’t need to take into consideration existential threats just like the local weather disaster.

“If a restaurant highlights the vegetable patty as an alternative of the meat patty as an ordinary possibility in its burger menu, it communicates: ‘Company at this restaurant often order the veggie burger.’ In psychology, we name this a descriptive norm.

“This presumed data of what others do in a sure scenario – no matter whether or not it’s desired or accepted – can have a big affect on behaviour.”
