The Global Food and Environment Institute is delighted to invite you to join our February 2022 webinar.

During this talk, Dr Evangelos Pournaras will highlight the findings from his research in this area.

In a so-called overpopulated world, sustainable consumption is of existential importance. However, the expanding spectrum of product choices and their production complexity challenge consumers to make informed and value-sensitive decisions.

Recent approaches based on (personalized) psychological manipulation are often intransparent, potentially privacy-invasive, and inconsistent with (informational) self-determination.

By contrast, responsible consumption based on informed choices currently requires reasoning to an extent that tends to overwhelm human cognitive capacity. As a result, a collective shift towards sustainable consumption remains a grand challenge. 

Dr Pournaras will show here a novel personal shopping assistant implemented as a smartphone app that supports a value-sensitive design and leverages sustainability awareness, using experts’ knowledge and ‘wisdom of the crowd’ for transparent product information and explainable product ratings.

Real-world field experiments in two supermarkets confirm higher sustainability awareness and a bottom-up behavioural shift towards more sustainable consumption. These results encourage novel business models for retailers and producers, ethically aligned with consumer preferences and with higher sustainability.
