Shared micromobility harms the climate

Zürich, January 2022

Rented e-scooters and e-bikes harm the climate more than they are good. Because they typically replace even more sustainable means of transport and transportation methods. This is shown by a study by ETH Zurich.

Shared micromobility is more harmful to the climate than expected. This is shown by a study by the Swiss Federal Institute of Technology in Zurich ( ETH ). This becomes clear if the evaluation of the climate impact of micromobility also includes how electric scooters and bicycles are actually used: “At first glance, e-scooters and e-bikes are climate-friendly because they do not have internal combustion engines,” says Daniel Jan Reck from the Institute for Transport Planning and Systems at ETH Zurich in a report by ETH. “Ultimately, however, what is decisive for their carbon footprint is which modes of transport they typically replace.”

The transport researchers working with Reck were able to show in their study that shared e-scooters and e-bikes in the city of Zurich mainly replace sustainable modes of transport: walking, using local public transport and cycling. They do more harm than good to the climate. “I think the sharing principle makes sense,” said Reck. “With micromobility and its climate impacts, however, the situation actually seems to be the other way around.”

The picture is different for privately used e-scooters and e-bikes. These replace more frequent journeys with one’s own car. This is why private micromobility reduces CO2 emissions “and benefits the climate on balance”. That is why it makes sense for authorities to promote commuting by means of private micromobility.

For his research, Reck received the Young Researcher of the Year Award from the International Transport Forum of the OECD in summer 2021. The think tank of the industrialized countries, based in Paris, awards the prize to young researchers whose work is important in matters of transport policy.
