• In the course of this thesis, an overview will be given on which way developers can guide users into acting environmentally friendly without the users realizing they are being nudged. In the last couple of years, our private and work-life have been more and more shifted away from reality into a digital context. Since the start of the Covid – 19 pandemic in 2019, even more aspects of everyday life have been shifted to an online context, one of them being groceries shopping. Even though online groceries shopping is not yet common in Germany, there is a trend toward the online purchase of groceries visible. This can be seen as a possibility to tackle another challenge the world is facing, the climate crisis. One reason for the climate crisis is mindless consumption and purchasing of too much food. This paper aims to combine the need for more aware consumption with the newly rising trend of online supermarkets. Furthermore, a supermarket will be provided to show if the implementation of environmentally–friendly nudges is technically possible. To eventually prove the effectiveness of a nudge, it needs to be tested. Keywords: Nudging, Environment, Online supermarkets
