How CarSharing Works

CarSharing is a more convenient type of car rental that can be used as little as 15 minutes, to a few hours, or for multiple days. Users can reserve vehicles any time through the reservation system and access them on their own with their membership card. The vehicles are picked up and returned to the same location, and users only pay for the time and distance they used the vehicle.

Benefits of CarSharing for Businesses

  • Cuts costs on the purchase and maintenance of vehicles. Gas, insurance, and maintenance are all included.
  • Advanced scheduling software allows fewer vehicles to serve a larger number of employees.
  • No upfront costs: converts vehicle ownership from a fixed cost to a variable cost.
  • Automatic employee mileage tracking and reporting.
  • Low administrative overhead; simplified mileage reimbursement process.
  • Encourages employees to take sustainable commute transportation options by offering a vehicle to use when needed during the workday.
  • Discounts may be available for usage during business hours.


CarShares in Boulder County

eGo CarShare started in 2001 as Colorado’s first nonprofit carshare organization, as well as one of the first in the nation. Their mission is to empower people to live a car-lite lifestyle and have a positive impact on the environment, their community, their health. They provide access to a network of 50+ energy-efficient vehicles throughout Boulder and Denver, providing members with improved mobility, cost savings, and environmental benefits.
As a local nonprofit carshare organization, we eGo Carshare is specifically focused on supporting the local community. In addition to more mainstream markets, they also serve underserved areas, and therefore the entire community. In doing so, they have cars throughout the city, providing needed transportation where people both live AND work. This means Boulder County residents and employees have a real, viable alternative to car ownership or can feasibly downsize the number of households cars. The better performing locations (e.g. downtown cars) enable them to place cars in other areas, such as low-income neighborhoods. Having a network of locations which serve the entire Boulder County community translates into more impactful and equitable mobility options for everyone.
They actively work to keep their margins, and therefore their rates, as low as possible so that they are affordable for businesses, students, residents, and employees of all income levels. Additionally, as a local non-profit, money stays and is reinvested in the local community through other mission-driven activity, such as education and outreach, local employment, and internships for local university students and others in the community.
