Examining the Influence of Educational Posters on People’s Food Choice Jiang, Mingxin; Jia, Xichang; Song, Yorke; Li, Yudie


Our current study aimed at examining how educational posters combining traffic light labels and CO2 emission data influence people’s sustainable food choice. We hypothesized that the poster combining traffic light labels and CO2 emission data will increase willingness to choose sustainable food, and other conditions will increase people’s willingness to a lesser degree. Due to the impact of COVID-19, we published an online survey to collect data. Our participants were randomly assigned into the four conditions in the survey. They were first shown posters with different elements (meaning different conditions), and answered the same set of questions, asking about willingness to choose pepperoni pizza, English muffin, and plant-based salad. Also, they were asked about future willingness to choose more sustainable food. After collecting data, we used one-way between groups ANOVA tests to analyze them. Unfortunately, we only found statistical significance in increased willingness to choose plant-based food in two conditions, and trivial statistical significance in increased willingness for future sustainable food choice. Therefore, the result did not generally support our hypothesis.
