Calgary Carshare, a non-profit member-owned co-op, was legally incorporated as the Calgary Alternative Transportation Co-Operative (CATCO) in 1999. Among our original purposes were the intentions to reduce car dependency, the environmental impacts of vehicles, and the financial cost of these vehicles for members. We started with one van and a few members in Sunnyside. Fifteen years, six vehicles and 150+ members later, we continue to work with community partners and support local initiatives in addition to running Calgary's first carshare service. Our carshare model support environmental sustainability and real transportation choice: members access transit, cycle and/or walk the majority of the time, using a carshare vehicle when those options are not available and/or do not make the most sense for the trip involved.
