I. BACKGROUND


Global Carbon* Emissions: 7.5 GtC/Y and Rising (Pacala & Socolow

Science, August 2004. *C = 3.67 CO2)


Abatement Opportunities Over Time (McKinsey 2009)


Abatement Opportunities Detail (McKinsey 2009)


CO2 Emissions / Capita / Year (2006) (UN, World Bank)

• 19.3 mt*: US Total

• 9.4 mt: US Personal (HVAC, transport, misc.)

• 4.3 mt: Global

• Major sources of CO2 emissions:

– Individuals: air travel

– Non-individual sources: power, buildings, transport, other industry, agriculture, forestry

*1 mt = 2,205 pounds


US Personal CO2 Emissions / Capita (2 Person Household)

Emission Source CO2 (mt) % Total

Vehicles (US EPA) 5.7 61

Home (electricity) (US EPA) 2.6 28

Waste (US EPA) 0.5 5

Other 0.6 6

Total Household (US EPA) 9.4 100

Air Travel: CO2 / Mi (000) (atmosfair,

WebFlyer)

.3-.5


II. TRANSPORTATION ALTERNATIVES AND BENEFITS


Transportation is One Major Source of Emissions

• Pacala and Socolow: automobiles constitute one of essential “wedges”

• Transportation ~ 1/3 US Emissions

• EPA Keys to Reducing Transportation Emissions:

– Improved vehicle technology

– Reducing miles driven

– Lower carbon fuel


Performance of Transportation AlternativesMode MPG City CO2 (10,000 Mi)

2009 Ford F-150 Pickup 4.6L Auto 15 6.27 mt

2009 Honda Accord 2DR 2.4L Auto5 21 4.18 mt

2009 Honda Civic 1.8L Auto5 25 3.58 mt

2009 Toyota Prius 48 2.18 mt

Motorbike 125-500 CC 48* 1.96 mt

Bus 56* 1.68 mt

Electrical Vehicles NA 1.36 mt**

Subway 75* 1.26 mt

*GCCC Estimate**Lincoln Electrical Vehicles


Public Transportation Benefits

– Reduced emissions.

– Reduced energy consumption.

– Greater social equity.

– Improved health.

– Reduced infrastructure cost.

– Reduced transportation cost.


III. INDUCING BEHAVIORAL CHANGE

-Transit Accessibility Index (TAI)

-Green Your Meeting (GYM)


-Transit Accessibility Index (TAI)

• Measure:

– Particular location (venue)

– Time and day of week

– Independent measurements:

• Originating locations independent of destinations

• Terminating locations independent of origination

• Definition: Accessibility: service w/i 1 mile at desired time and day


Green Your Meeting (GYM)

• A demand side approach to behavioral change.

• Plan meetings around transit accessibility.

• Utilizes the present “as built” environment.


V. CASE STUDY: FAIRFAX COUNTY DOT


Meeting Requirements

• Two Public Meetings to Review Fairfax County Department of Transportation (FCDOT) Proposals

• Evening 6-8:30 PM

• Distributed Geographically

• Close to Metro Lines

• 15 Potential Public Facilities


Potential Locations


Sample Starting / Ending Points


TAI: Maryland and Virginia


TAI: Virginia Only
