Two CNG Vehicles in Use
2000 GMC Box Truck 2002 Chevrolet Express Cargo Van

Why Do We Have Them?
• To Act on the Institute’s Commitment to Reduce the Environmental Impact of its Operations
• Road Test the Technology• Demonstrate Leadership in and Feasibility of
Campus Applications of Alternative-Fuel Vehicles

How Did We Choose CNG?
• Best Available Technology• No Gasoline-Electric Hybrids• No Biodiesel• No Appropriate Electric Options• Required a Duel-Fuel Technology to Reduce Risk
web.mit.edu/environment
How Has CNG Worked for Us?• Excellent performance – No Compromises• No Additional Maintenance or Maintenance Costs• Less Expensive Fuel - $80-$100 vs. $160/week• Fast Filling Rate – Same as Gas• Only Weekly Fill Required (Recycling Truck)• No Dead-Heading for Recycling Truck Fuel Trips• Builds Awareness of and Recognition for
Environmentally Responsible Action

What Are the Drawbacks?• Increased Cost for CNG Retrofits • No Local Fueling Locations – Everett, MA• High Cost and Political Barriers to Local Filling
Station Siting• Limited Scalability with No Local Filling• May Not be Competitive with Newer Technologies:
• Environmental Performance (GHG/methane)• Ease of Use / Convenience (vs. hybrid, etc.)

What Does the Future Hold?• Should Periodically Assess Options• CNG May Not be the Choice in the Future• Other Technologies Now Viable
• Clean Diesel / ULSD• Biodiesel• Gas-Electric Hybrid, Other?
• Have to Consider Local Situation & Opportunities, e.g. Cambridge DPW
• Need for Campus-Wide Alt. Vehicle Guidance
