“We tested the effectiveness of different messages aimed at addressing climate change and created a tool that can be deployed by both lawmakers and practitioners to generate support for climate policy or to encourage action,” says Madalina Vlasceanu, an assistant professor in New York University’s Department of Psychology and the paper’s lead author. The tool, which the researchers describe as a “Climate Intervention Webapp,” takes into account an array of targeted audiences in the studied countries, ranging from nationality and political ideology to age, gender, education, and income level. “To maximize their impact, policymakers and advocates can assess which messaging is most promising for their publics,” adds paper author Kimberly Doell, a senior scientist at the University of Vienna who led the project with Vlasceanu.

Method:Three participatory workshops were held with the independent Welsh residential decarbonisation advisory group(‘the Advisory Group’)to (1)maprelationships betweenactors, behavioursand influences onbehaviourwithin thehome retrofitsystem,(2)provide training in the Behaviour Change Wheel framework(3)use these to developpolicy recommendationsfor interventions. Recommendations were analysed usingthe COM-B (capability, opportunity, motivation) model of behaviourtoassesswhether they addressed these factors. Results:Twobehavioural systems mapswere produced,representing privately rented and owner-occupied housing tenures. The main causal pathways and feedback loops in each map are described.
