Leaving sustainable behaviours to science rather than chance

Did you know that changing behaviours takes more than just education and awareness? And that changing them necessitates taking into account both conscious and unconscious influences? We use proven scientific models and tools designed specifically for sustainable behaviours.


We want to learn more about the personal, contextual, and social barriers that keep people from engaging in sustainable behaviours. To go beyond declarative data and consider conscious and unconscious influences, we conduct literature reviews and use implicit research methods.

Case study



We use our Rainbow Database TM, which contains over 60 sustainable behaviour interventions, to select the most appropriate ones for your project, ranging from communications to service provision. We then co-create these interventions with stakeholders and users to develop more equitable and effective solutions.

Case study



We help you implement and evaluate these interventions throughout your ecosystem, including as part of campaigns and existing programmes. We do this on our own or in collaboration with your existing partners, such as market research and communications agencies, depending on your project.

Capability building

We hold training sessions on a regular basis to help participants understand and apply behavioural science for sustainable outcomes, from practical knowledge to ready-to-use tools. We also train students at institutions such as Bournemouth University (UK), the University of Geneva (CH), Erasmus University Rotterdam (NL) and EDHEC Business School (FR).
