Carsharing
Carsharing or car sharing or car clubs refers to several models of car rental or car use, where people rent cars for short periods of time, often by the hour. Unlike traditional car rental, collecting and returning the vehicle is often self-service through a mobile app and without entering an office or agency. It also often differs in the length of hire and the cost structure. In some models a commercial company owns the fleet and offers it for member use. In other models the owners are private individuals who organise as a cooperative or ad hoc grouping, or list their vehicles with a separate car sharing facilitator. Car sharing is part of a larger trend of shared mobility.
Car sharing began in Europe in the late 1940s, before spreading to North America, and is now an international phenomenon. The 2024 global market size for car sharing was valued at US$ 4.7 billion to 8.9 billion. Car sharing is growing: projections of the 2033 global market size range from US$14.3 to 24.4 billion. Europe was the global car sharing leader in 2024, with the highest adoption and market share at 38%. Emerging markets include Latin America, the Middle East and Africa, driven by demographic trends, economic development, and regulatory change.
Car sharing has been shown to lower car ownership and usage. Car sharing can reduce traffic congestion, lower greenhouse gas emissions and improve air quality.
History
1940s–1970s: European Cooperative Origin
Car sharing began with early European cooperative models aimed at community resource sharing rather than commercial profit. The first documented instance was the Selbstfahrergemeinschaft cooperative in Zurich, Switzerland, established in 1948. It was largely motivated by economic reasons, enabling individuals who could not afford to purchase cars to share access to one vehicle. The operating model, centered around a small user group, was an early form of the Station-Based/Round-Trip service, where a vehicle was reserved and returned to its original location. The 1970s saw more ambitious, though ultimately short-lived, experiments, including the coin-operated Procotip system in Montpelier, France and the notable electric-vehicle-based Witkar in Amsterdam. These early programs struggled due to small scale and planning issues, demonstrating that convenience and high vehicle utilization were key to the model's eventual success. Many other shared car experiments were attempted but were unable to grow large enough to sustain, among them: Green Cars, Bilpoolen, and Bilkooperativ.1980s–1990s: Growth and North American introduction
Car sharing saw a resurgence around the 1980s and 1990s with organised, membership-based car sharing programs, particularly in the US and Europe. These were mostly smaller non-profit, cooperative organizations, like StattAuto in Germany, which established viable operational models. similar to initiatives in the Netherlands and in Sweden. In the U.S., early programs like Mobility Enterprise and the Short-Term Auto Rental program in San Francisco were similarly short-lived. North America had a restart of in their carsharing movement in the 1990s, when Communauto was founded in Quebec City, Canada in 1994, followed shortly thereafter by the first official U.S. operator, CarSharing Portland, in Oregon in 1998, which started with one vehicle and a few neighbors.Early 2000s: Commercialisation and technological disruption
The growth of car sharing began in the early 2000s, driven by technological advances in communication and reservation systems, as well as rising urbanisation and environmental concerns. The 2000s also marked the commercialisation of car sharing with the launch of major, venture-backed companies.Founded in Cambridge, Massachusetts, in January 2000, Zipcar quickly established the commercial Station-Based model in the United States. The subsequent decade brought profound technological disruption via smartphones and GPS. This led to the introduction of the highly flexible Free-Floating model around 2008/2009, allowing users to pick up and drop off vehicles anywhere within a defined service zone. At the same time, the Peer-to-Peer model emerged, pioneered by platforms like Turo and Getaround, which expanded the accessible fleet by allowing private car owners to rent out their personal vehicles. Several car rental companies launched their own car sharing services beginning in 2008, including Avis on Location by Avis, Hertz on Demand, operating in the U.S. and Europe; Uhaul Car Share owned by U-Haul, and WeCar by Enterprise Rent-A-Car. In 2010 Zipcar accounted for 80% of the U.S. car sharing market and half of all car-sharers worldwide.
In the mid-2010s, car-sharing was becoming an international transportation trend, especially in metropolitan areas. Car sharing also spread to other nations, including Brazil, Mexico, Turkey, China, and India. Zarcar, founded in Rio de Janeiro in 2009, was the first car-sharing system in South America. According to Moscow's authority, the number of carsharing journeys in the city averaged 30,000 a day between January and September 2018.
The main factors driving the growth of carsharing were the rising levels of congestion faced by city dwellers, shifting generational mindsets about car ownership, the increasing costs of personal vehicle ownership and a convergence of business models.
2020s and future: Global scale and electric integration
Today car sharing operates on a large global scale, driven by rising traffic congestion, digital technologies, and a shift away from individual car ownership. All commercial models of car sharing - Station-Based, Free-Floating, P2P - coexist and are rapidly integrating technology like AI for fleet management. A major industry trend is the increasing adoption of Electric Vehicles, supported by governments and consumer demand for sustainable transportation.Market size
Estimations of the 2024 global market size for car sharing differ, from US$ 4.7 billion to 8.9 billion. Projections of the 2033 global market size range from US$ 14.3 to 24.4 billion. Europe was the global car sharing leader in 2024, with the highest adoption and market share at 38%. In Europe the car sharing market is expected to reach €4-5 billion by 2030.One report predicts global car sharing membership to grow to 138.3 million by the end of 2029 and a total car sharing fleet of about 755,000 cars. The corporate carsharing market is forecasted to reach about 270,000 vehicles in 2029.
The Asia-Pacific region is projected to experience the highest growth, at 15.8% from 2025 to 2033, due to rapid urbanisation, an expanding middle-class, and increasing smartphone penetration. China, Japan and South Korea lead growth in this region. Emerging car sharing markets include Latin America, the Middle East and Africa, driven by demographic trends, economic development, and regulatory change.
Types of car sharing
Car sharing programs can either be commercial business-to-consumer or peer-to-peer. Within commercial car sharing schemes, the most prominent models are Station-Based and Free-Floating.Business-to-consumer
In the B2C model, a carsharing provider owns and maintains a fleet of vehicles accessible to members for short-term use. B2C car sharing can be station-based or one-way/free-floating.Unlike traditional car hire, B2C car sharing is a fully automated, 24/7 self-service model. Having passed a one-time membership approval process, including background driving checks and payment verification, users can locate and unlock vehicles instantly via a mobile app. Rentals are by the minute or hour, and rates typically include the cost of fuel and insurance. While traditional rentals typically focus on centralised hubs like airports, B2C carsharing vehicles are distributed throughout urban service areas, often placed near public transport to facilitate "last-mile" connectivity. Unlike traditional rentals, vehicles are often maintained and cleaned on a schedule but not between every individual use. Fleet operators utilize decentralized refueling methods, such as mobile fuel trucks used by Yandex.Drive, or rely on members to refuel when levels are low, with costs borne by the provider. Additionally, although carsharing services meet the legal minimum insurance requirements, their insurance policies vary significantly, and the model has been criticised for providing lower liability coverage compared to the more comprehensive protections typically provided by established traditional car rental companies.
Round trip/Station-based car sharing
With station-based car sharing, the cars are permanently stationed at designated stations, typically reserved parking spaces. Members pick up the vehicle at the station, and must return it there. The car must usually be reserved for a specific amount of time in advance, and must be returned before that time ends. Payment is usually both by the hour, and by the distance driven. In exchange, a vehicle can be reserved days or weeks in advance, and it is often possible to reserve a specific type of vehicle, such as one with more seats or greater cargo capacity.One-way/free-floating car sharing
One-way car sharing enables users to begin and end their trip at different locations. The pick-up and drop-off locations can be either free floating zones or restricted to station-based models with designated parking locations.As of 2017, free-floating car sharing was available in 55 cities and 20 countries worldwide, with 40,000 vehicles and serving 5.6 million users, with Europe and North America representing the majority of the market. In Europe in 2019, free floating services took up more than 65% of car sharing membership. By the end of 2022 the service was expected to reach 14.3 million users with more than 100,000 vehicles woldwide. However, growth patterns vary among cities and some have reached a saturation point where no increased fleet size or additional service needed.
Corporate car sharing
Companies may also use fleet cars when employees need vehicles occasionally rather than permanently, such as for meetings, site visits, or short business trips. Instead of assigning one car per employee, vehicles are shared among multiple users and booked when needed.
