Municipal fleets can be optimized to reduce energy use, cost, and greenhouse gas emissions. In the 2007 Throne Speech, the Province of BC committed to all new fleet purchases being hybrid-electric vehicles.
One approach to fleet optimization that is gaining momentum with local governments is the E3 Fleet program delivered by the Fraser Basin Council. E3 Fleet helps on-road vehicle fleets reduce smog and greenhouse gas emissions that contribute to climate change. Find out more at http://www.e3fleet.com.
A BC example from 2006, the City of Dawson Creek implemented a Green Municipal Vehicle Purchasing policy, with assistance on design of the policy from the Pembina Institute. Their policy can be found here: http://www.planningforpeople.ca/what_we_are_doing/energy_plan/phase_1/index.asp
