Does Car-Sharing Reduce Car-Use? An Impact Evaluation of Car-Sharing in Flanders, Belgium
Sustainability, 2020
Private car-use is a major contributor of greenhouse gases. Car-sharing is often hypothesised as a potential solution to reduce car-ownership, which can lead to car-sharing users reducing their car-use. However, there is a risk that car-sharing may also increase car-use amongst some users. Existing studies on the impacts of car-sharing on car-use are often based on estimates of the users’ own judgement of the effects; few studies make use of quasi-experimental methods. In this paper, the impact of car-sharing on car-ownership and car-use in Flanders, Belgium is estimated using survey data from both sharers and non-sharers. The impact on car-use is estimated using zero-inflated negative binomial regression, applied to matched samples of car-sharing users and non-users. The results show that the car-sharing may reduce car-use, but only if a significant number of users reduce their car-ownership. Policy intervention may therefore be required to ensure car-sharing leads to a reduction i...

Free-floating carsharing, i.e., carsharing that allows pick-up and return of a car anywhere within a specified area in a city, has now been available in European cities for more than 10 years. As an important example of the sharing economy, carsharing strives for a more efficient use of resources with positive economic, social, and environmental impacts. After a decade of operation and user experience, an evaluation seems appropriate. car2go and DriveNow, who merged into SHARE NOW in 2019, are the largest carsharing operators in the world. They commissioned this study to identify the impact of carsharing on vehicle holdings, modal shift, vehicle kilometers traveled (VKT), and greenhouse gas emissions. The study was conducted in 2018 and 2019. It is based on a survey among car2go and DriveNow customers in 11 European cities. A previous study was performed by the University of California, Berkeley, for 5 North American cities in 2016 [7]. [...]
Investigating the Potential of Ridesharing to Reduce Vehicle Emissions
Urban Planning, 2017
As urban populations grow, cities need new strategies to maintain a good standard of living while enhancing services and infrastructure development. A key area for improving city operations and spatial layout is the transportation of people and goods. While conventional transportation systems (i.e., fossil fuel based) are struggling to serve mobility needs for growing populations, they also represent serious environmental threats. Alternative-fuel vehicles can reduce emissions that contribute to local air pollution and greenhouse gases as mobility needs grow. However, even if alternative-powered vehicles were widely employed, road congestion would still increase. This paper investigates ridesharing as a mobility option to reduce emissions (carbon, particulates and ozone) while accommodating growing transportation needs and reducing overall congestion. The potential of ridesharing to reduce carbon emissions from personal vehicles in Changsha, China, is examined by reviewing mobility ...
sustainability Impact of Car Sharing on Urban Sustainability
Sustainability, 2021
The article gives us an insight into the key issues of car sharing and its impact on urban sustainability. A selection of 314 articles published in peer-reviewed journals from the Scopus database were analysed using Leximancer 5.0 for Automated Content analysis. A total of seven themes were identified explaining the researched topic of the car sharing situation in Europe, which are sharing, economy, model, systems, electrical car sharing, policy and travel. There are two ways of sharing owned cars in Europe; access to cars from the fleet of private organisations and P2P car sharing. Sustainable environmental solutions in the context of the electrification of cars are used. Car sharing usually takes place online and can be free or for a fee as defined by The European Economic and Social Committee. The article provides an overview of understanding the concept of urban car sharing in Europe.
Car-Sharing as an Environmental Policy Tool: A Preliminary Analysis
2014
In recent years, energy prices have become increasingly more expensive. This trend has added to auto ownership costs and uncertainty about future operating expenses. Furthermore, parking in many of the world’s largest cities is limited and costly further adding to private vehicle expenditures. Many nations worldwide have adopted carsharing (or short-term auto access) as a mean of reducing personal transportation cost and the negative impacts of wide spread auto use (congestion, inefficient land use, energy consumption and emissions). The objective of this paper is to present the notion of car-sharing. Therefore, it begins with the definition, the function and the pricing policy of car-sharing. Then, the history and growth of car-sharing are presented. Additionally, advantages and disadvantages of this alternative choice of mobility are analyzed. Finally, the implementation of car-sharing in different continents is mentioned and a number of ways that could improve the effectiveness o...
Does Car Sharing Contribute to Urban Sustainability from User-Motivation Perspectives?
Sustainability
Mobility, its current state and development perspectives in the future creates challenges with respect to sustainability, the first of which is the uncontrolled increase in greenhouse gas emissions in the last few decades, while road transport is one of the “sinners” creating long-term negative impact. The second is the dominance of car travel and car usage in the passenger transportation segment before the latest COVID-19 pandemic accelerated environmental problems. Although recent trends show new, greener patterns in consumption, there is still a relatively low share of consumers acknowledging the importance of sustainable and green preferences. This research study aims to investigate car sharing from users’ perspectives and to determine the most significant factors influencing their choice of sharing services to ensure upscaling of car sharing and, thus, contribute to urban sustainability. This research study contributes to the overall scientific discussion on car sharing and its...
Mobility styles and car sharing use in Europe: attitudes, behaviours, motives and sustainability
European Transport Research Review
What are the profiles of both users and non-users of car sharing in European cities regarding their travel patterns and psychological aspects? Two subsamples (1519 users and 3695 non-users of car sharing) participated in a survey, translated into seven languages, with 36 questions regarding attitudes towards car sharing, the environment, political orientation, personal norms, frequency of use of different transport modes and transport mode choice for different travel purposes. Through a hierarchical cluster analysis, five distinct mobility styles were identified, with no a priori restriction of the number of clusters. The mobility styles were further characterised by sociodemographic variables and by the motives for making use of car sharing. This paper discusses the implications of research based decision-making and urban planning in a way that guarantees long-term human and environmental security.
