EVs make car sharing even better
Visit any big city, and you’ll witness how shared transportation options have grown, from electric scooters tossed along sidewalks to bike and car sharing services. These can be a (relatively) cheap and easy way to zip around city streets. But the real potential of these shared services goes well beyond cities and well-heeled urbanites. In the case of car sharing, if the program is designed strategically—including prioritizing the use of electric vehicles (EVs)—there are prospects for a triple win: convenient transportation, lower emissions, and more affordable mobility options.
Car sharing has a lot going for it. Worldwide, membership in car sharing organizations like Zipcar and Getaround—which offer users access to a fleet of ready-to-drive cars, typically via an app—doubled between 2016 and 2018, to more than 30 million. People are flocking to shared cars for a lot of reasons, but the main ones are convenience and cost savings. Car sharing (which is different from car rentals or ride-hailing services like Uber and Lyft) offers the benefit of using a vehicle without the high costs associated with private car ownership, like insurance, gas, maintenance, and parking. Usually, vehicles are stationed in locations like residential neighborhoods or near public transit stations and universities, making them convenient for a wide range of users.
Car sharing, if done well, can also be a great way to tackle rising emissions from transportation, the fastest growing source of greenhouse gas emissions worldwide. Studies show that when people gain access to a shared vehicle, they may get rid of their private car or avoid buying a new one; they also tend to walk, bike, or take public transit more. This brings other cascading benefits, including reducing the overall vehicle miles traveled and lowering traffic congestion and the demand for parking—all of which help slash driving-related emissions. Overall, the research points to a decrease in net greenhouse gas emissions among car sharing members, although it can depend on the context.
Car sharing also has real potential to provide more equitable access to transport. So far, car sharing companies have focused on urban centers, but rural communities can actually benefit most from these services, due to the lack of density to support traditional public transit, biking, or other options. By making car sharing services available to more people, including in lower-income and more remote neighborhoods, we can go even further in reducing emissions.
