In episode 41, we speak with Steven Van Passel, Professor in Environmental Economics and Vice-Rector for Valorisation and Sustainability at the University of Antwerp.Steven leads the EnvEcon group, a multidisciplinary research team focused on sustainability assessments in energy, food systems, and the circular economy. With a background in agricultural economics and years of experience advising climate and nitrogen panels, Steven offers a grounded, systems-level view on how to move from research to real-world impact.We talk about how to translate science into societal value, why systems thinking is essential, and what role technology should play in the sustainable transition of our built environment.Show notes:
