Reducing Air Emissions from Transportation and Construction What Boston-Area Universities and Colleges Can Do--- Presented by: David E. Harris Jr. David E. Harris Jr. General Manager, Transportation Services Carl A. Tempesta Operations Manager, Transportation Services

Global Warming - Rising sea level, drought, tropical disease, extinction, famine, flooding, …. Air Pollution - Smog, asthma, bronchitis, acid rain, cancer, …. Why Should We Use Alternative Fuel Vehicles (AFV’s)?

Why Use Alternative Fuel Vehicles (AFV’s)? Urban Air Pollution Vehicular emissions are a major source of air pollutants, including: –nitrous oxides (NO x ) –hydrocarbons (VOCs) –particulate matter (Pm) –carbon monoxide (CO) –sulfur dioxide (SO 2 )

Why Use Alternative Fuel Vehicles (AFV’s)? Voluntary and Non-Regulated Approach Town Gown---Cambridge/Boston Supports the Mission of Harvard’s Green Campus Initiative “A Vision of Harvard University becoming a global leader in addressing the most important issue of our times: the global environmental imperative.” It’s Fun!

These effectiveness figures are provisional values subject to change pending final review of the test data.

Barriers to Implementation Entry Cost Return on Investment Regulations- City/Local/State Overcoming doubts/questions about technology Availability of Solution/Technology

Data from What Have We Learned?

BioDiesel Can Be Used in Multiple Types of Equipment Volvo LD50 Chevrolet Duramax TopKick w/ CAT 3208

Harvard Equipment Powered by Biodiesel

What Have We Learned? Positive Feedback from Community and Peers It really does smell better! Cold Weather!Biodiesel does perform well in Cold Weather! Engine warranties are not at risk Limited suppliers Cost benefits to on-site fueling On-going Analysis—Oil testing, Emissions, Vehicle maintenance
