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 (NOx)– hydrocarbons (VOCs)– particulate matter (Pm)– carbon monoxide (CO)– sulfur dioxide (SO2)

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!
