To encourage GCF staff and project developers to identify potential behavioural opportunities, the IEU presents a short list of considerations to highlight which elements of GCF projects may benefit from the application of behavioural science. These are all elements where groups of people must adopt a new behaviour, make a complex decision or execute a complex task. The list of considerations can be utilized during the review and appraisal of project proposals. If deemed relevant, project developers could adjust proposals to realize behavioural opportunities.
