Evaluating nudge and boost strategies for greener meals in food-delivery: An experimental study

emissions, whereas the boost intervention yielded considerably smaller and less consistent effects. However, neither intervention produced lasting effects in the follow-up survey, where choice architecture reverted to the control condition. Moreover, while higher CRSC induced lower emissions, neither the nudge nor the boost elevated CRSC, and thus the hypothesized mediating role of consumer responsibility was not supported. We discuss the theoretical and practical implications of these results for the design of effective sustainable food choice interventions.
