Putting climate impact labels on fast food menu items could encourage people to choose more sustainable menu options, according to international researchers. The team found that, when food was negatively labelled as having a 'high-climate impact', 23% more participants ordered sustainable, non-red meat options. When food was positively labelled as being 'low-climate impact' options, 10% more participants ordered sustainable items. The findings suggest that labelling foods with their climate impacts might be effective in promoting more sustainable choices, the team says.
