To better understand food wasting behaviour, the theory of planned behaviour was used to inform the development of a survey which was administered to households in London, Ontario, Canada. Respondent households (n = 1,263) threw out avoidable food waste 4.77 times/week (SD = 4.81, Mdn = 4.0) and 5.89 food portions/week (SD = 5.66, Mdn = 4.0). When asked to choose one of three possible motivators to reduce food wasting behaviour, 58.9% selected reducing monetary loss as their first choice and this was significantly (p < 0.001) higher than both reducing environmental impact (23.9%) and reducing social impacts (17.2%). A linear hierarchical regression analysis (R²= 0.30, p < 0.001) on intention to avoid food waste demonstrated that perceived behavioural control (p < 0.001) and personal norms (p < 0.001) had the greatest positive impact on intention. A linear hierarchical …
