Emission trend in SF Bay Area Tunnel: Car/SUV VOC emission rate is dropping about 13%/year; gasoline consumption is increasing about 2.7%/year in fast-growing areas of California. So total VOC still declining more than 10%/year.

Denver vehicle inspection data, 1996-2002
Improvements will continue
Automobile emissions are dropping about 10%/year as fleet turns over to inherently cleaner cars, SUVs, pickups
Fleet meeting 2004 EPA standards—the fleet that will be on the road in 15-20 years—will be at least 90% cleaner per-mile than current average car
Net reductions of more than 80%, even after accounting for VMT growth
Diesel truck standards were tightened in 1998 and 2003. Additional 90% reduction required in 2007
But anti-automobile activists aren’t aware of the real-world data
“sprawl and higher-emitting SUVs are proliferating faster than technological fixes can keep up.” – David Goldberg, Smart Growth America in the Atlanta Journal-Constitution 2003
