消除塑料垃圾在一定程度上依赖于改变人类行为。本综述旨在(A)使用AACTT(行动-行动者-情境-目标-时间)框架来识别和分类相关行为，(B)使用COM-B(能力-机会-动机-行为)模型来识别、分类和评估可能与这些行为相关的变量，(C)使用行为改变轮和行为改变技术分类来识别、分类和评估干预措施的性质。一项系统的文献搜索确定了60项与塑料垃圾相关的行为研究。Meta分析被用来量化(I)变量和行为之间关系的强度和方向，以及(Ii)干预成分对行为变化的影响。研究主要集中在普通公众(行为者)、回收(行动)、购物(背景)和有限范围的塑料废物。反映能力、机会和动机的变量都与行为有中等强度的关联。与行为变化最强烈相关的干预类型是“说服”、“使能”和“环境重组”。与行为变化最大相关的政策选项是“沟通和营销”、“环境和社会规划”以及“提供服务”。以“心理能力”为目标的干预措施对减少塑料垃圾的行为有负面影响，而以“身体机会”和“反思动机”为目标的干预措施的积极作用最强。所有已确定的行为改变技术对行为改变都有中等到很大的影响。综上所述，这些发现为未来的研究和减少塑料垃圾的努力提供了明确的方向。
Eliminating plastic waste relies, in part, on changing human behaviour. This review aimed to (a) use the AACTT (Action-Actor-Context-Target-Time) framework to identify and categorise relevant behaviours, (b) use the COM-B (Capability-Opportunity-Motivation-Behaviour) model to identify, categorise and evaluate variables that might be associated with these behaviours, (c) use the Behaviour Change Wheel and the Behaviour Change Techniques Taxonomy to identify, categorise and evaluate the nature of interventions. A systematic literature search identified 60 studies of behaviour relating to plastic waste. Meta-analysis was used to quantify (i) the strength and direction of the relationship between variables and behaviour and (ii) the impact of intervention components on changes in behaviour. Studies focused predominantly on the general public (actors), recycling (action), shopping (context), and a limited range of plastic waste items. Variables reflecting capability, opportunity, and motivation all had medium-strength associations with behaviour. The intervention types associated with the strongest changes in behaviour were ‘persuasion’, ‘enablement’ and ‘environmental restructuring’. The policy options associated with strongest changes in behaviour were ‘communications and marketing’, ‘environmental and social planning’ and ‘service provision’. Interventions targeting ‘psychological capability’ had a negative effect on plastic waste reducing behaviours while interventions targeting ‘physical opportunity’ and ‘reflective motivation’ had the strongest positive effects. All identified behaviour change techniques had medium to large effects on changes in behaviour. Taken together, the findings provide clear directions for future research and efforts to reduce plastic waste.
