Making the carbon basket count: Goal setting promotes sustainable consumption in a simulated online supermarket

Abstract

We compared the effectiveness of basket goal-setting to product information strategies on sustainable consumption in a simulated online supermarket. Experiment 1 found a significant effect of basket goal setting techniques with carbon basket feedback in either numerical or graphical form on the carbon content of baskets purchased but no effect of numerical product information alone or in combination with basket CO2 information. Experiment 2 also found that basket goal setting was effective, but found no additional effect of introducing five-colour coding of the carbon footprints of either products or baskets. Experiment 3 found that repeated visits to the online supermarket led to improved learning about product carbon footprint in the basket goal setting condition, which mediated the effect of goal setting on basket carbon footprint. Our results suggest that goal setting techniques with feedback can reduce the carbon footprint of online shopping baskets and facilitate learning about product carbon footprint.
