Colorado CarShare was started by a group of Boulder citizens who were concerned about minimizing their environmental impact, and who strived to leave a more sustainable legacy for future generations. They took the issue of transportation to heart and made a commitment to minimize their automobile use. In 1997, the "Little Red Car Co-op" was formed. The momentum continued forward, and in 1998, Boulder CarShare (BCS) was founded.
The organization was incorporated as a Colorado non-profit on August 28, 1998. Approval by the IRS as a 501(c)(3) entity came on April 3, 2006. Boulder CarShare rebranded in January 2009 as eGo CarShare in order to expand its service to the City of Denver. In March of 2009 eGo CarShare placed its first three cars in Denver and in the Fall of 2009 eGo CarShare received its first significant outside funding from a Congestion Mitigation and Air Quality (CMAQ) grant to aid in its expansion to core Denver neighborhoods. This funding accelerated eGo's transition from a small, local program, to a regional force in the carsharing industry representing over 3,000 members and managing 45+ vehicles. In the past two years eGo has been growing at a rate of 30-50% per year.
In the past few years the carsharing industry has been evolving and growing rapidly, and several large, for-profit carshare providers have recently expanded to Denver. CO CarShare remains the only non-profit carshare provider in the region and is the longest running and largest round-trip carsharing program in the area. CO CarShare remains committed to ensuring that its program addresses transportation equity issues as directly and comprehensively as possible and consequently CO CarShare's usage rates ($5.50/hr) are about half that of national, corporate carshare companies such as Zipcar ($9-10/hr).
