To address the prominent “value‐action gap” within pro‐environmental behaviour, this novel, cross‐sectional study investigated relationships between household food wasting and pro‐environmentalism. Research was undertaken in 11 neighbourhoods across London, Ontario, Canada, including a net‐zero energy neighbourhood. A direct measurement methodology was used to measure household food waste, and a survey was created to measure knowledge, attitudes, and behaviours related to food wasting. Households in the net‐zero energy neighbourhood sent between 2.59 kg and 2.80 kg of food waste to landfill per week, of which 68% was classified as avoidable and the remaining 32% as unavoidable. Households in this neighbourhood sent less total (p < 0.001) and unavoidable (p < 0.001) food waste to landfill than households in “regular” neighbourhoods within the same city. While participants in the net‐zero neighbourhood had strong, self‐reported pro‐environmental worldviews, pro‐environmentalism was not found to be stronger in this neighbourhood compared to the rest of the city. The presence of stronger, self‐reported pro‐environmental worldviews was associated with a decrease in unavoidable food waste generation (p < 0.01). As the first study of its kind, further research is needed to verify the role of pro‐environmentalism in household food wasting in Canada and beyond.

净零能源社区的家庭食物浪费：分析家庭食物浪费与环保主义之间的关系

为了解决环保行为中突出的“价值行动差距”，这项新颖的横断面研究调查了家庭食物浪费和环保主义之间的关系。研究在加拿大安大略省伦敦的 11 个社区进行，其中包括一个净零能源社区。使用直接测量方法来测量家庭食物浪费，并创建了一项调查来测量与食物浪费相关的知识、态度和行为。净零能源社区的家庭每周将 2.59 公斤至 2.80 公斤的食物垃圾送往垃圾填埋场，其中 68% 被列为可避免的，其余 32% 为不可避免的。该社区的家庭向垃圾填埋场发送的食物垃圾总量（p < 0.001）和不可避免的食物垃圾（p < 0.001）少于同一城市内“常规”社区的家庭。虽然净零社区的参与者有强烈的、自我报告的支持环境的世界观，但与城市其他地区相比，该社区的支持环境主义并没有更强。更强烈的、自我报告的环保世界观的存在与不可避免的食物浪费产生的减少有关（p < 0.01）。作为此类研究中的第一项，需要进一步研究来验证环保主义在加拿大及其他地区家庭食物浪费中的作用。
