      Influences on single-use and reusable cup use: a multidisciplinary mixed-methods approach to designing interventions reducing plastic waste

            Background : An estimated 2.5-5 billion single-use coffee cups are disposed of annually in the UK, most of which consist of a plastic lining. Due to the difficulty of recycling poly-coated material, most of these cups end up as litter or in landfill. As hot beverage consumption is a consumer behaviour, behaviour change interventions are necessary to reduce the environmental impacts of single-use coffee cup waste. Basing the design of interventions on a theoretical understanding of behaviour increases transparency of the development process, the likelihood that the desired changes in behaviour will occur and the potential to synthesise findings across studies. Aim: The present paper presents a methodology for identifying influences on using single-use use and reusable cups as a basis for designing intervention strategies. Method and application : An online survey and follow-up interviews were developed by a multi-disciplinary group of practitioners, health psychologists, material scientists, behavioural scientists and catering staff. They used two behaviour change frameworks: The Theoretical Domains Framework and Capability-Opportunity-Motivation-Behaviour model of behaviour. Research findings can inform selection of intervention strategies using a third framework, the Behaviour Change Wheel. The application of the methodology is illustrated in relation the setting of a university campus. Conclusions : We have developed a detailed method for identifying behavioural influences relevant to pro-environmental behaviours, together with practical guidance for each step and a worked example.
