Just Eat and Deliveroo lowers carbon footprint of dishes, says study led at Cambridge Judge Business School
London, November 18, 2024, (Oilandgaspress) ––– As the COP29 climate summit continues in Baku, Azerbaijan, we thought that an article posted today on Cambridge Judge Business School’s website about how menu positioning on food-deivery apps can lower the carbon footprint may be of interest to you and your readers.
App-based and online food delivery services such as Deliveroo and Just Eat in the UK and DoorDash in the US are increasingly popular, so how can policymakers influence consumer decisions to reduce the carbon footprint of food choices made on these platforms?
Such policy interventions are vitally important given that greenhouse gas emissions from the food system, including production, transport and packaging, constitute about one-third of the global total. Meat production is far more carbon-emitting than other farming given methane gas from cattle, fertiliser used in animal-feed crop production, and much greater land use in farming livestock compared to other farming.
Research led by Cambridge Judge Business School finds that adjusting the order of food on delivery-app menus – so the lowest carbon-impact dishes and restaurants are presented first – significantly reduces the average meal carbon footprint, while a meal tax (which adjusts meal prices based on the carbon content of their meat ingredients) and carbon-footprint label (providing information) have little such effect.
Such menu positioning, known as ‘choice-architecture intervention’, reduced the average meal order carbon footprint by 12% per order, driven by a 13% reduction in high-carbon main meal choices.
