Purpose: Reducing food waste is one of the critical challenges of campus canteens. This study aims to test an extended theory of planned behaviour that incorporates moral norm, food taste and campus food-saving climate to understand the influence factors of food waste behaviour on campuses.Design/methodology/approach: To evaluate the proposed model, an online survey was utilized to collect 513 valid questionnaires.Findings: The findings suggest that (1) attitudes towards food waste, subjective norm and perceived behavioural control have a significant influence on intention to reduce food waste; (2) Moral norm and food taste are shown to have a favourable effect on the intention to reduce food waste; (3) Food waste behaviour is significantly determined by intention to reduce food waste; (4) Campus food-saving climate negatively moderates the relationship between intention to reduce food waste and food waste behaviour.Originality/value: This study paves the way to enhance the understanding of the factors of food waste among college students. In addition, this study develops practical strategies to prevent large amounts of food from being wasted on campus.

Purpose: The COVID-19 outbreak has been rapidly spreading around the world for more than a year. However, few studies have explored the connection between the perceived severity of COVID-19 and purchase intention of the health-related products, for example, organic food. Based on the stimulus–organism–response (S-O-R) framework, this study examines the influencing mechanism of perceived severity of COVID-19 on purchase intention of organic food.Design/methodology/approach: To evaluate the proposed model, an online survey was utilized to collect 1,104 valid questionnaires from China.Findings: The findings suggest that (1) the perceived severity of COVID-19 has a significant positive impact on purchasing intention; (2) health consciousness acts as a mediating role between perceived severity of COVID-19 and purchasing intention and (3) perceived inconvenience negatively moderates the connection between perceived severity and purchase intention.Originality/value: The findings of this paper provide new insights into the positive effects of COVID-19 and pave the way for governments and enterprises to promote the purchase behaviour of organic food.
