Reducing greenhouse gas emissions and non-communicable diseases requires large-scale lifestyle changes, especially in transport and food. However, behaviours such as car use or meat consumption are shaped by habits, structural constraints, and social context. This talk presents three complementary approaches:
- Understanding behaviour change mechanisms through mixed methods, highlighting attitudes and socio-spatial constraints;
- Designing and evaluating interventions, illustrated by a 24-month randomised controlled trial combining free public transport and behaviour change techniques;
- Integrating policy context, showing that identity influences support for environmental policies.
Together, these findings highlight the need for interdisciplinary, policy-relevant approaches to sustainable behaviour change.
About the speaker
Claudia Teran-Escobar is an Associate Professor in Social and Health Psychology at Université Paris Nanterre (LAPPS). Her research sits at the intersection of behaviour change and planetary health, aiming to understand why sustainable behaviours remain difficult to adopt despite growing awareness. She studies how psychological mechanisms interact with social and structural constraints to shape behaviours such as mobility choices, meat consumption, and support for climate policies. Through interdisciplinary collaborations and rigorous experimental designs, her work seeks to develop and evaluate interventions that can effectively support large-scale societal transitions.
