Global food consumption threatens climate stability and ecosystem
resilience. Because hard regulation of food choice through taxes and bans is
politically difficult, behavioral approaches provide a promising alternative,
given that they influence food choice to a meaningful extent. We test the
effect of framing of a menu on the choice of ordering climate-friendly dishes
in a randomized controlled experiment. Rearranging the menu in favor of
vegetarian food has a large and significant effect on the willingness to order a
vegetarian dish instead of meat. Our results demonstrate that small,
inexpensive interventions can be used toward decreasing carbon emissions
from food consumption.
