The Power of Plant-Based Nudges in Food Services – One Green Planet

In cafeterias across schools, hospitals, and universities, subtle changes are leading a quiet revolution toward plant-based eating. By strategically placing plant-based options in prominent locations, giving them appealing names like “feel good” or “juicy,” and making meat an option that must be requested, food services are encouraging diners to choose more sustainable meals without feeling deprived.

This shift is part of a broader strategy to reduce the environmental impact of food choices. Animal agriculture is a significant contributor to global greenhouse gas emissions, accounting for about 14.5% of the total. By nudging people towards plant-based meals, institutions can make a meaningful impact on reducing these emissions.

Nudge theory, popularized by the 2008 book Nudge: Improving Decisions about Health, Wealth, and Happiness, is the driving force behind this strategy. It involves small, low-effort changes that influence behavior without restricting options. For example, by simply renaming vegan dishes with more enticing descriptions, Google’s cafeterias have seen an increase in the selection of plant-based meals.

Several institutions are already seeing success with these tactics. In New York City, public hospitals now offer plant-based meals as the default option. UC San Diego Health has significantly cut its red meat purchases and food-related emissions. Sodexo North America is expanding plant-based dining across university campuses, achieving notable reductions in emissions.

These initiatives demonstrate that plant-based nudges can effectively shift eating habits towards more sustainable choices, all without sparking political or cultural backlash. As Jennifer Channin from the Better Food Foundation notes, these nudges are not only discreet but also foster positive attitudes towards plant-based foods.
