Study Gives Canadian City Path to Reduce GHG Emissions

If you’d like some insight into how cities are grappling with alternative energy sources for city vehicles and operations, a recent study concluded that Mississauga, Canada’s sixth largest city with a population of more than 700,000, could reduce GHG emissions by downsizing some of its fleet vehicles and converting to fuel efficient or hybrid electric vehicles. The study also recommends purchasing biodiesel fuel to reach the city’s corporate operations emissions reduction target.

City fleets reviewed in the study included vehicles no larger than three quarters of a ton used by transit, recreation and parks, fire and emergency services, parking enforcement and corporate services, as well as the personal vehicles of city employees used for city business. 

Mississauga looked at opportunities of assigning the right size of vehicles to specific job functions and converting vehicles to fuel efficient or hybrid electric vehicles where possible. Of the 211 vehicles considered, 113 (or 54 per cent) were identified for downsizing and converting to smaller, fuel efficient vehicles.

The city is also considering purchasing  biodiesel B5 grade if the price is at or below the 2006 diesel price.

The study found that approximately 548 tonnes of GHG emissions can be reduced by converting the 113 vehicles over a five-year replacement schedule.  Through the purchase of B5 grade biodiesel for city fleets, about 97 tonnes of GHGs can be reduced.  An additional 1,538 tonnes can be reduced by using B5 biodiesel for fueling Mississauga Transit buses. 

By right-sizing the corporate fleet and transit small fleet, a net reduction of approximately $227,000 could be realized over the course of the five-year replacement program.  There would be a cumulative savings of approximately $446,000 in fuel costs, based on the current cost per litre for the corporate fleet and transit small fleet.  After the five-year replacement program is completed, ongoing annual savings were estimated at $125,000.

One thought on “Study Gives Canadian City Path to Reduce GHG Emissions

  1. Biodieselhas not been proven to be more efficient than regular diesel. It requires much fuel to grow and process, as well as stealing land that could grow food. Hybrids and electric vehicles also consume more fuel than can be recovered. Follow the production, refinging and all the steps invloved in the production and use of the alternatives. Go from cradle to grave. You can reduce fuel usage byat least half by using European technology, and vehicles. Mobilonce had a program for rating vehicles on the basis of miles per gallon (mpg) and ton-miles per gallon (tmpg). If you remove all the extra weight of the electric motors, batteries and associated machines from ahybrid, youcan improve the fuel mileage by at least 10%. Electric vehicles also require much more fuel to generate, tranmit, charge batteries, and then run the auto. There are many steps involved, and no step is 100% efficient. multiply each step’s efficiency with the preceding step’s efficiency to evaluate the overall decrease in power from the primary power source. Chase it down for yourselves to see how you are being misled.
