Study finds that increased vehicle travel and decreased occupancy have undercut the impact of improving fuel economy over last 40 years

Green Car Congress

Sivak found that while the vehicle fuel economy of the entire light-duty fleet improved by 40% (from 13 mpg US to 21.6 l/100km), because of the decrease in vehicle load, the occupant fuel economy only improved by 17% (from 24.8 Combining these two effects yields a reduction of about 14% in the amount of fuel used.

Belfer Center Study Concludes Reducing Car and Truck GHG Emissions Will Require Substantially Higher Fuel Prices; Income Tax Credits for Advanced Alt Fuel Vehicles Are Essentially Ineffective at Reducing Sector Emissions

Green Car Congress

Economy-wide CO 2 prices of $30-60/t CO 2 are too weak on their own to motivate significant reductions in CO 2 emissions from transportation. The economy-wide CO 2 prices applied increase the cost of driving only marginally with respect to the business-as-usual case. Adoption of all of the preceding policies.

Study Finds That Implementation of a Portfolio of Transportation Strategies Will Be Required for Significant Reductions in GHG from Transportation Sector; Pricing Strategies Have the Largest Potential

Green Car Congress

Strong economy-wide pricing measures (such as a $5.00 per gallon fuel tax by 2050) could result in an additional reduction of 28% in GHG emissions. The Moving Cooler baseline extrapolated these projections further to 2050, resulting in a potential doubling or greater of fleet fuel efficiency. Land use and smart growth.
