A project aimed at evaluating the feasibility, costs, and environmental benefits of switching 5 campus-owned diesel vehicles to run on a 20% biodiesel fuel blend instead of 100% petrodiesel. The project includes research on other schools' experiences, infrastructure changes, engine warranties, and cost comparisons. The document also provides an estimate of the potential environmental benefits and savings.

Project Goal: To evaluate the costs, environmental benefits, and feasibility of switching campus-owned diesel vehicles to run on a 20% biodiesel fuel blend instead of 100% petrodiesel 1
Why switch to biodiesel?
Evaluation Process
Project Specifics:
(^1) Number of diesel gallons used at Wellesley in 2006 (^2) National Biodiesel Board. http://www.nationalbiodieselboard.org/.
Conversion of campus-owned maintenance vehicles to biodiesel
Petrodiesel cost: Average price paid by Wellesley during 2006 (Burke Oil): $2.31 per gallon petrodiesel
Biodiesel costs/savings: Current estimate of $0.12 increase per gallon (Burke Oil): $2.43 per gallon biodiesel = 9,419 gallons^1 * $0.12= $1130. 5% increase Low estimate of $0.07 decrease per gallon (assuming March, 2007 prices): $2.38 per gallon biodiesel = 9,419 gallons * $-0.07= -$659. 3% savings High estimate of $0.24 increase per gallon (Burke Oil): $2.55 per gallon biodiesel = 9,419 gallons * $0.24 = $2260. 10% increase
Environmental Benefits from B20 use (compared to petrodiesel)^2 :
