“…Thus, both the car-ownership effect and the ATT estimated for the weak cut-off group appear to be outliers compared to the other European studies. These results would seem to add weight to other recent studies that have found that car-sharing may not be as environmentally beneficial as previously thought [5,6,28].…”

“…In contrast, an inhabitant who does not have a car (and had no plans to buy one, thus his/her car-ownership is unaffected by the introduction of car-sharing) will increase his/her access to cars by joining car-sharing, which can lead to an increase in car-use. This relationship has been uncovered empirically in other studies, such as Martin and Shaheen [3] and Wu et al [15], and is also discussed by Jung and Koo [6] and Ke et al [28]. These hypothetical examples show that it is crucial to first establish the effect on car-ownership before estimating the effect on car-use.…”

Does Car-Sharing Reduce Car-Use? An Impact Evaluation of Car-Sharing in Flanders, Belgium

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 in car-use by, for example, discouraging car-ownership. Further research using quasi-experimental methods is required to illuminate whether the promise of car-sharing is reflected in reality.

“…Ideally, car owners that switch to this service sell their cars or decide to not repurchase a new car when their old car reaches its end of life, whereas non car owners may decide to use the service on demand without the necessity of a car purchase. Yet, based on a game-theoretic model, Ke et al (2019) found that car sharing does not always reduce vehicle quantity; it does so, only under specific conditions. Furthermore, there is a lack of proof that the reduction of car ownership will lead to the reduction of car-use (Chapman et al 2020).…”

Business models can be created by combining business model patterns. The use of patterns can stimulate creativity of entrepreneurs and support the design of innovative business models for sustainability. In this article, we analyze the frameworks on sustainable business model (SBM) patterns, which can be mainly classified along the three dimensions of the triple bottom line (TBL): economic, environmental, and social. Furthermore, we introduce the concept of “truly sustainable business models” by drawing on contingency and system theory. We observe that the simple application of the frameworks of business model patterns by combining economic, environmental, and social business model patterns for sustainability into one single business model does not necessarily lead to a truly sustainable business model. Therefore, the combination of patterns along the TBL seems a necessary, but not sufficient condition for achieving true sustainability, and hence, the mere reliance on SBM patterns in business model design can be misleading to entrepreneurs. Our conceptual work advances research related to frameworks on SBM patterns by identifying three critical levels for the analysis of whether a business model is truly sustainable or not. The first level is inherent to the business model as a system; the second is related to the larger system, in which the business model is embedded; and the third is about the contingency factors that can impact the sustainability effectiveness of the business model over time.

“…Electric vehicles and mobility sharing have attracted research attention from scholars across the academic spectrum, such as transportation (e.g., [14]), management (e.g., [15]), energy and environmental studies (e.g., [16]). From the energy and environment side, electric vehicles have been commonly proven to be greener compared to the conventional internal combustion engine vehicles (e.g., [17]).…”

“…The results indicate that car sharing does not always reduce vehicle quantity. Specifically, only when the producing cost and transportation need are below some thresholds and the market size is greater than a threshold, can car sharing decrease the total number of vehicles [14]. However, the problem of electric vehicle sharing is neither equal to the pure car-sharing problem, nor to the simple combination of the electric vehicle and the car-sharing because of the synergy, since electric vehicles differ from ICVs in the energy cost, government support, etc., to a large extent.…”

CO2 emissions reduction has long been discussed, since the problem is one of the most urgent issues we human beings are faced with in the 21st century. Time-sharing electric vehicles (TSEVs), combining the benefits of cleaner energy and more sufficient utilization, are considered a sustainable future transportation tool, with increasing support from governments around the world. Although numerous studies have been carried out in this domain, few have studied the development process, considering the inverse interrelations, including the policy implementation effects and user choice, in a dynamic way. This research fills the previous academic gap and presents a system dynamics (SD) model incorporating scenario analysis to simulate the effect of introducing time-sharing electric vehicles in changing the user quantities in transportation tools, including public and private sectors, under different levels of government subsidies, thus providing policy implications and ex-ante assessment for the subsidies. The results suggest that it is not the greater the subsidy, the better the effect. Considering that one of the purposes of introducing TSEVs is to reduce private vehicles, there is a threshold for user transfer. It is actually under low subsidy that private internal combustion engine vehicle (ICV) users are most attracted to the TSEVs compared to the medium and high ones. The gap between the simulation results and common sense reminds us that ex-ante assessment and overall planning in the process of industry development are necessary.
