An investigation into sustainable transport options
Notice bibliographique
Résumé
The University of British Columbia (UBC) prides itself in being a national leader of sustainable development and studies. The UBC Farm is a center for sustainable learning and teachings. Therefore, it is critical that thorough investigations into sustainable options are completed before the farm makes major purchases. The UBC Farm has asked teams of the APSC 261 course to look into a triple bottom line assessment of sustainable transport options. UBC Farm needs to replace its aging gasoline operated farm and delivery vehicle. The UBC Farm is looking for a new vehicle to use to transport produce to the market, relocate machinery, and transport employees around Vancouver. Requirements given include: must reliably run for at least 3 years, is highly fuel efficient, able to be maintained by the university, by plant-ops garage staff specifically, and is either a small truck or a 10 passenger van. Due to personnel and time constraints three options were investigated: using a car co-op’s services, purchasing a diesel engine vehicle, and purchasing a diesel vehicle and using bio-diesel. The investigation has found that purchasing a diesel vehicle and fueling it with bio-diesel is the recommended choice of action. While Modo has offered discounts on their services, the inconvenience of traveling off campus to find and retrieve a vehicle out ways the potential cost savings and the ability to spread the knowledge of car sharing. Diesel engines are more efficient than conventional gasoline engines, and used vehicles are relatively inexpensive; emissions are a concern with older models. Bio-diesel is available on campus, at the same price as conventional diesel, and has less emission problems as conventional diesel. Furthermore, the bio-diesel is partially renewable and a diesel engine truck will not need to be converted if the model year is after 1994. Investigating all the options, bio-diesel is ultimately the best choice economically, environmentally, and socially.

Prédiction distillée sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Apprise à partir de 10 348 étiquettes directes de Codex et de 10 348 étiquettes directes de Gemma. Le mode candidate est l'union des têtes enseignantes seuillées; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont ni des étiquettes humaines ni des étiquettes directes de modèles de pointe.
