Fuel economy of light-duty vehicles is another important factor. The decline in new light-duty vehicle fuel economy between 1990 and 2004 reflected the increasing market share of light-duty trucks, which grew from about 29.6% Emissions from petroleum consumption for transportation decreased by 4.0% following a decrease of 3.7%
