Plastic pollution is one of the biggest environmental problems in the world. In modern society, the consumption of single-use plastics in the food service industry has increased along with the increase in food-away-from-home. The COVID-19 pandemic has attacked the consumption of single-use plastic in the restaurant industry. During the COVID-19 pandemic, especially the US has retracted the related laws and policies regarding using single-use plastic for fast food and carry-out food, and customers have increased their use of single-use plastic for fast food and carry-out food due to worries about hygiene. Even though sustainability has been a novel topic in hospitality literature, a majority of studies have focused on the consumers’ perception, attitude, or behavioral willingness toward sustainability. To fill this gap in research, finding an effective way to influence consumers’ behavioral change becomes important and necessary.
