The Leftovers Club | Episode 1: Why Aren’t We Sharing Our
Food? The Psychology Behind Global Waste

Why does collective food sharing – a simple, high-impactsolution
to global food waste - remain a niche behavior?

In this debut episode of Food Sharing: The Leftovers Club,hosts
Miru, Rebecca and Sebi dissect global food waste through an
academic and behavioral science lens, connectingmicro-level
consumer habits to UN sustainable Development Goal 12.3.

The team breaks down the three structural models of food sharing:
commercial surplus discounting, institutional redistribution, and
peer-to-peer exchange. They examine why food sharing remains a
niche behavior, analyzing psychological barriers such as trust
deficit, social stigma, and cognitive biases, as well as
structural and legal barriers disrupting habit formation. The
empirical core of the episode compares student perspectives
across four European university contexts to assess the systemic
and psychological viability of “Fair-Teiler” community fridges in
Salzburg (Austria), Marseille (France), Bucharest (Romania)
andMadrid (Spain).

Discover how social norm nudges, public disclosure and structural
support can transform local campus initiatives into scalable
mechanisms for sustainable behavior change.

This episode was created as part of the CIVIS Blended Intensive
Programme “Nature, Society & Psychology of the Climate
Crisis” hosted in Salzburg.
