Policy evaluation: online takeaways

Delivery food apps, such as Deliveroo or UberEats, have become increasingly popular in recent years, with projections suggesting that up to 100 million people will be using them across Europe by 2024. These apps have made it easier than ever before to have meals delivered directly to homes, providing a convenient and quick option for busy individuals. However, despite their rapidly growing importance, the impact that these apps have on diets and the environment has received little attention. Encouraging more sustainable diets on online delivery platforms is important, as it can help to reduce the environmental footprint of our food choices, while also promoting healthier eating habits.

The goal of this study is to understand the potential of using behaviour-based policies to promote environmentally friendly food choices on food delivery apps. In order to achieve this, an interactive web-platform that mimics an online takeaway food setting will be used. The platform will include 3 treatment conditions: a meat tax, a carbon footprint label, and a choice architecture intervention. The meat tax treatment will apply a surcharge on meat dishes, while the carbon footprint label treatment will provide information on the carbon footprint of each dish. The choice architecture intervention will re-order the menu so that the lowest carbon-impact dishes are presented first. The study design will allow for the comparison of the effectiveness of a conventional monetary intervention, information provision and a behavioural intervention in the same experimental setting, and aim to generate new understanding of the potential impact on both personal welfare and distributional effects.
