How value-sensitive design can empower sustainable consumption.

Area of Science:

• Environmental Science
• Consumer Behavior
• Human-Computer Interaction

Background:

• Sustainable consumption is crucial due to global overpopulation and complex production.
• Current methods for informed choices overwhelm consumer cognitive capacity.
• Existing psychological manipulation tactics raise privacy and ethical concerns.

Purpose of the Study:

• To develop a novel personal shopping assistant app to support value-sensitive sustainable consumption.
• To leverage expert knowledge and crowdsourced data for transparent product information and ratings.
• To address challenges in consumer decision-making for sustainable products.

Main Methods:

• Implementation of a smartphone application with a value-sensitive design.
• Integration of expert knowledge and 'wisdom of the crowd' for product assessment.
• Conducting real-world field experiments in supermarket settings.

Main Results:

• The app demonstrably increased sustainability awareness among consumers.
• A measurable bottom-up behavioral shift towards more sustainable consumption was observed.
• The study provides evidence for effective, transparent product information delivery.

Conclusions:

• The developed app effectively supports informed and value-sensitive consumer decisions.
• The findings encourage new, ethically aligned business models for retailers and producers.
• This approach facilitates a collective shift towards sustainable consumption patterns.
