Intentions and Knowledge Improve Eco-Foodprint


Intentions and Knowledge Improve Eco-Foodprint


Fabke, A., Jost, S., Lindenburger, V., ErgĂĽn, E.


We investigated how and when providing information about CO2-Emissions of groceries or letting participants set implementation intentions influences the ecological footprint of grocery shopping. We suggested that providing knowledge would reduce the Eco-Footprint while setting intentions would only show an effect, when knowledge was also given. Indeed, we found support for both hypotheses in a field experiment. After two weeks of shopping, participants who were given information about eco-friendly product alternatives, reported to have bought more organic meat. Additionally, participants who set implementation intentions only reported a higher purchasing of organic fruit and vegetables, when information was provided as well.
