Using electric scooters or even electric bikes is not for everyone and not for every occasion! These are means of fair weather transportation!
Of course, no word about the production and charging of these vehicles and batteries and its environmental impact.
The referenced study by the Fraunhofer Institute for Systems and Innovation Research seems not peer reviewed. It has more the appearance of a rubber stamp marketing material!
"... Coverage often focuses scooter crashes, the devices parked haphazardly on the sidewalk and the congestion of too many scooter operators. But these fail to point out the environmental and economic benefits micromobility bring to cities.
For example, Lime recently gave its scooter data to German research institute Fraunhofer ISI, and the organization found that shared e-scooters help reduce carbon emissions within city transportation networks. The researchers surveyed Lime riders in spring 2022 across Stockholm, Paris, Melbourne, Berlin, Seattle and Dusseldorf and found that in each city, if shared scooters and bikes hadn’t been available, a significant number of riders would have taken their most recent trips via car, taxi or ride-hail. ..."
From the abstract:
"Shared micromobility, i.e. shared e-scooters and e-bikes, has become a widely used service, particularly for urban travelers. While previous work has primarily focused on who uses these for which purposes, the discussion about the consequences of usage has just begun, such as the effect for transportation sector emissions. Previous studies have captured snapshots of shared micromobility’s net sustainability impact from 2018 through 2021, with a trajectory of improvement that nonetheless fell short of reducing carbon emissions. To provide a 2022 update, we collect survey data from shared micromobility riders in six cities across the globe (Berlin, Dusseldorf, Paris, Stockholm, Melbourne and Seattle; n=4,167). To calculate the emission impact, we adapt existing life cycle assessment data to the characteristics of the cities surveyed and apply information of a shared micromobility provider. The largest shift effects are from walking, PT, ridehailing, and private vehicles to shared micromobility. In all six cities studied, shared micromobility shows emission reductions compared to the modes replaced. This effect is more positive for shared e-scooters than shared e-bikes, due to differences in their relative embedded carbon and life spans. Shared micromobility providers have opportunities to further decarbonize by continuing to move to all-electric operations, decarbonizing material extraction, increasing the vehicles' lifespans, and leveraging partnerships with PT agencies and shared mobility services like ridehailing to increase mode shift from motor vehicles. Our results also point to the importance of cities implementing solutions like protected bike lanes or travel cost and time increases for individual motorized transport."
Shared e‑scooters reduce carbon emissions, finds leading German research institute Fraunhofer ISI The usage of shared micromobility services has increased in recent years, particularly in urban areas. But can shared e-scooters and e-bikes contribute to the sustainability of cities and their transportation systems? To answer these and other questions, Fraunhofer ISI conducted a new study on behalf of the micromobility provider Lime by fusing mode shift survey data with lifecycle emissions data in six cities around the world. The study also sets out what implications these findings have for industry and practice.
