The firm, which now has operations in more than 500 cities and towns in eight countries across the globe, says its annual member survey revealed that nearly 10% of members have disposed of a car after joining, and 32% would have purchased a vehicle without the presence of Zipcar. As a result it has helped eliminate the need for 400,000 personally owned vehicles. 

The firm is also launching a new Zipcar free-floating car-sharing model this autumn.  

“For the past 16 years Zipcar has been driven by its vision of a world where car sharers outnumber car owners,” said Nicholas Cole, President, Zipcar International. “While we’re pleased to have hit the million member milestone, Zipcar views success by the collective impact our community of a million members have had on the globe. With less cars on the road, cities can build more green space, reduce parking and congestion challenges and overall create a better place to live.”
