Zipcar today released the findings of its 2018 Impact Report during the Transportation Research Board Annual Meeting in Washington, D.C.

The report – for the first time – comprehensively captures key findings gathered over Zipcar’s eighteen years of mobility leadership.

The findings, combined with objective third-party research, offer tangible evidence that car sharing continues to provide both members, and the cities they live in, with significant and distinct social and environmental benefits, at a time when new mobility offerings are on the rise.

Car sharing Frees Up Space for Other Pressing Urban Uses

  • Zipcar’s 12,000 vehicle fleet means an estimated 156,000 fewer cars on city streets. 5
  • The average parking space occupies 200 square feet, 6 freeing up space for housing, green areas, office space and more.

Car sharing Sheds Personal Vehicles and Helps the Environment

  •  Each Zipcar on the road eliminates the need for up to 13 personally-owned vehicles. 1
  •  Car-sharing members reduce their CO2 footprint by up to 1,600 pounds per year. 4

Zipcar is Key to a Multimodal Lifestyle that Enables the Right Mode for the Right Trip: Car-sharing Members Take Longer, More Purpose-Driven Trips

  • Data shows Zipsters rely on walking, biking and public transit for short trips, and turn to car sharing for longer, purpose-driven or recreational trips to out-of-town destinations. 3
  • The average Ziptrip in North America is 47 miles. 4

Car sharing Delivers Distinct Social Benefits 

  • 42% now report being able to affordably reach critical destinations like school and work. 3
  • 87% of Zipsters spend less money per month on transportation when compared to the U.S. monthly average. 3
