Why Use Alternative Fuel Vehicles (AFVs)?

• 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)

4
Why Use Alternative Fuel Vehicles (AFVs)?

• Voluntary and Non-Regulated Approach
• Town Gown---Cambridge/Boston
• Supports the Mission of Harvards 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.
• Its Fun!

What are the Options?
Gasoline Diesel/ ULSD Compressed Natural Gas
(CNG) Liquefied Petroleum Gas (LPG)
Fossil Fuels
Biomass
Ethanol Biodiesel
Any Source
Electricity /Hydrogen Fuel Cells

Total PM reduction figures reflect reductions
from both tailpipe and crankcase emissions. 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
