Car sharing, one of the most quickly growing forms of collaborative consumption, is often hailed as a way to enjoy access to a car when you need one, without the cost and inconvenience of owning one when you don't.
With studies showing that most personal vehicles sit idle almost 23 hours out of every day, it's no wonder that many families have actually given up vehicle ownership to take advantage of the money saving benefits of a car sharing program instead.
But a recent study by the University of California at Berkeley found that saving money isn't the only compelling reason to support car sharing initiatives.
An online survey of over 9,500 individuals living in Canada and the United States revealed that car sharing programs have the power to significantly reduce overall greenhouse gas emissions in North America.
The survey, which polled members of major car sharing organizations, found that for most car sharing members, individual greenhouse gas emissions increased because the program provided access to a personal vehicle for the first time. However, these small individual increases were outweighed by the significant number of people able to drastically reduce their emissions through car sharing.
"The number of carless households increasing their emissions is comparatively large, constituting more than half of the respondents," noted the researches. "However, the degree to which these households are increasing emissions as a result of carsharing is small on an individual basis. The overall emission reduction is driven by the remaining respondents reducing their emissions by larger amounts that compensate for increases of the majority."
Among multivehicle households shedding cars, 88% of respondents reduced emissions. Similarly, among single-vehicle households shedding cars, 93% exhibited an emission reduction.
So where's this impact coming from?
In general, the researchers found that participating in a car sharing program helps members to embrace a low-mileage lifestyle, even though carless households converge to this lifestyle by increasing emissions, and car-holding households converge by going car free and decreasing emissions.

This is great idea and is true that it will help with lowering emissions apart from two things: 1. Is it safe enough? 2. I'm not sure I want to share my new Alfa Romeo Giulietta with anyone... ;-)

It's interesting to note that there is also peer-to-peer carsharing, which enables private people to rent out their cars to each other. We have been enabling private carsharing on https://www.rent-n-roll.de/ in Germany for about eight months now and hope to continue to grow. There is a lot of potential for this concept and we're glad companies like WhipCar and Getaround do the same in the UK and the US

If you really want to lower the emission of ones vehicle then they must use car evaporators to regulate the emission coming from the car. Electric cars are the cars to be.

Kenny, electric cars eliminate the pollution coming out of the tail pipe, that's true. Yet they're only as clean as the power source that's producing their electricity. If it's a coal-fired electric plant there's still a whole lot of CO2 coming out of that smoke stack.
Interesting study!
Ride sharing and car sharing should really be promoted together:
- someone without a car can hop in a ride and not always get his own vehicle from the car sharing service.
- someone who gets a car from the car-sharing service should be encouraged to offer empty seats online. It is likely that this person is more likely to share.
