In order to effectively change climate-related behaviours, we must be clear and specific about the behaviour that we’re hoping to change, understand the barrier(s) and/or faciliator(s) to the target behaviour, and implement a broad range of interventions to address and/or enhance the identified barrier(s) and/or facilitator(s). Using household recycling as an example, the purpose of this case study is to show how applying behavioural science can help to identify and implement a range of different intervention types that can help to effectively address behavioural determinants and influence behaviour.
