Dr Christian Bretter


I am a Research Fellow in Radical Transport Decarbonisation, particularly interested in the intersection of environmental behavior (such as transport usage or food waste), social psychology, and political psychology. Given my background as an engineer, I am mainly interested in applying (and learning) quantitative methods such as experimental designs, SEM, or panel data to achieve my research objectives. Nonetheless, I also use qualitative methods such as semi-structured interviews to gain better insights into specific phenomena. After completing my undergraduate degree and gaining significant experience in the industry, I sought to diversify my skill set and decided to study Engineering Business Management at the University of Warwick. It was here where I became interested in learning more about why people behave in certain ways and how, if possible at all, we can encourage them to change their behavior. After having spent another year in the UK construction sector, I went to the University of Leeds to dedicate the next three years to my PhD in Organisational Behaviour. These years have sparked my interest in understanding environmental behavior and the psychological factors that influence it. Hence I started working as an ESRC-funded Research Fellow in Enviornmental Psychology with particular focus on better undestanding the psychological and behavioural factors driving household food waste. Working with different institutions such as the Waste & Resource Action Programme (WRAP), I have also launched and tested different interventions to reduce household food waste in the UK. After successful completion of this project, I have now joined the Institute for Transport Studies (ITS) to examine, among other activities, the factors driving transport usage (particularly car use) and, building on this assessment, to explore possible avenues for behaviour change to reduce demand for individual car ownership.

Research interests

I am mainly interested in the intersection of environmental behavior (such as transport usage or food waste), social psychology, and political psychology. Understanding why humans behave environmentally (and why not) through the lens of social psychology and political psychology is at the core of my research. Before my current role, I was involved in an ESRC-funded project in which we examine the drivers of household food waste. Now, I am examining the drivers of different means of transport and how they change over time (car use in particular). Additionally, I am working on examining how human values shape individual approval of environmental policies and how such values may (or may not) change over time. Ultimately, I aim to conduct rigorous research that enhances our psychological understanding of environmental (and political) behavior, thereby informing policymakers and practitioners to make better-informed decisions.
