STUDY PURPOSE
- Review of trends in region’s vehicle fleet
- Assess impacts of market changes
- Apply latest planning assumptions in air quality analyses

TECHNICAL METHODS
- Obtain data files of registered vehicles in D.C, MD and VA
- Apply ‘VIN Decoder’ software to read files and tabulate according to vehicle type, weight, fuel use and year of manufacture
- Identify vehicle composition and changes since first use of decoder with 2005 data
- Develop input files for EPA’s Mobile 6 model- Re-estimate emissions factors for forecast year
analyses in current air quality conformity assessment

CONCLUSIONS: 2008 VS. 2005 FLEET
Factors Tending to Reduce Emissions:- Hybrid vehicles increasing dramatically (although
still small in absolute numbers)- Passenger cars vs. SUVs trends reversed, i.e., new car purchases increasing at the expense of SUVs
and light trucksFactors Tending to Increase Emissions:
- Fewer new vehicles being purchased- Emissions factors higher as a result, for both VOC
and NOx> up to10% higher rates in 2010> up to 4% higher rates in 2030

POLICY IMPLICATIONS
- Policy Initiatives on Capitol Hill (e.g., Cash for Clunkers)
- EPA Programs (e.g., heavy-duty truck retrofits and re-powering)
- DOE Energy Conservation Programs (e.g., Idle-Reduction Technologies)
