In 2009 and 2010 we deployed our first alternative fuel vehicles, and implemented a comprehensive emissions-reduction strategy and related policies.
Our main campus fleet successfully improved its fuel efficiency by 9% in 2010 by transitioning to new vehicle types. Transportation Services maintains a new vehicle procurement policy that emphasizes hybrid and low emission vehicles, and we've found these high-performance vehicles to be cost effective. We also strive to provide mobility with zero-emissions technology, such as bicycle patrols, Segway-style electric vehicle patrol, and all-electric parking patrol vehicles. Emissions are controlled via proper maintenance and idle-reduction practices for buses and other large vehicles.
Northeast Ohio is often listed as a non-attainment area for air quality due to particulate matter, largely generated by vehicles. We've implemented a "No Idle Zone" in our valet parking areas and in our delivery docks where vehicles are turned off during transactions. We instituted an anti-idling policy in June 2009 for our Cleveland Clinic Police Department that encourages officers to turn off engines, limiting idling to no more than 5 minutes.
Employee commuting is a large part of our emissions. To encourage low-carbon commuting, we incentivize bus ridership, offer a carpooling match program and preferred parking for carpools. We also offer purchase rebates and discounted parking to our employees who drive qualified low-emission vehicles. Over the past several years, we have added bike racks and shower access across the enterprise to encourage wellness and sustainable transportation.
In 2008 we completed our LEED Silver Certified Service Center, which increased our dock capacity 5-fold and introduced an improved dock scheduling system that creates narrow appointment windows for deliveries, greatly reducing truck wait time and subsequent idling. The service center docks were designated as no-idling zones, resulting in measurable savings and reduced emissions from idling at our busy docks.
Also in 2008, we introduced a new parking system at the Main Campus that shifted parking access from a badge swipe to an automated sensor (AVI) at our main campus garages. This technology has reduced idling time, queuing, and subsequent emissions.
