Comparative Analysis: EVs vs. Traditional Vehicles

While EVs offer significant environmental advantages, a direct comparison with traditional internal combustion engine (ICE) vehicles is crucial for a comprehensive understanding of their sustainability.

The Role of Transport Connectivity in Shared E-Mobility

The growth of shared mobility services, including electric car-sharing and e-bike sharing, is significantly influenced by transport connectivity. These services often complement public transport, serving as crucial first-mile and last-mile solutions.

E-bike and E-scooter Sharing

E-bikes and e-scooters have emerged as popular modes of shared electric mobility. Their usage patterns often align with commuting hours, making them efficient for short to medium distances. The time-saving potential of these micro-mobility options, due to their compact size and ability to navigate traffic congestion, is a significant advantage over traditional transport modes.

Spatial distribution of e-scooter trips can differ from bike-sharing, with e-scooters often used to improve accessibility to public transport systems. Trip purposes also vary, with e-bikes frequently used for commuting, while e-scooters see more use for social, shopping, and recreational purposes. The efficiency of e-bikes and e-scooters in covering short distances, often under 3 km, makes them strong alternatives to private cars, especially when considering their economic competitiveness.

Electric Carsharing

Electric carsharing services also contribute to sustainable urban mobility. While the trip distances for electric carsharing are often short, comparable to e-bikes, they offer an alternative for longer journeys or when carrying multiple passengers. The potential for electric carsharing to substitute private car use and reduce overall vehicle miles travelled (VMT) is a key environmental benefit.

Impacts of Shared E-Mobility

Shared e-mobility services have a wide-ranging impact on transportation, the environment, health, and society.

Transportation Impacts

• Mode Substitution: Shared EVs can replace private fossil-fuel-powered cars, leading to reduced driving distances and potentially lower total VMT. E-micromobility, such as e-bikes and e-scooters, shows a high potential for substituting car trips, especially for short distances.
• Induced Traveling: Shared e-mobility can enable trips that might not have been taken otherwise, potentially increasing overall travel but also improving accessibility for those with limited mobility.
• Car Ownership Reduction: The availability of shared mobility services can lead to a reduction in private car ownership, with associated benefits of reduced manufacturing emissions and parking pressure.
• Congestion: While shared e-mobility has the potential to reduce congestion by replacing car trips, the impact is still being studied, especially with the increasing popularity of micromobility.

Environmental Impacts

• Greenhouse Gas (GHG) Emission Reduction: Electric carsharing can reduce GHG emissions, particularly when replacing fossil-fuel vehicles. The lifecycle assessment, including battery production and electricity generation sources, is crucial for a complete picture.
