MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050).

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 occupants carried) decreased by 27% (from 1.9 mpg US, or from 18.1 l/100km to 10.9 mpg US to 29.8

The report reviews policies that bear upon two categories of choice: travel choices such as how and how far to travel and vehicle purchase choices. It also discusses fuel taxes and prices, which affect both travel and vehicle choices. It may also be possible to accelerate a shift to a much more efficient vehicle fleet.

Tax credits and gasoline prices necessary for various electric vehicles to be cost-competitive with conventional vehicles at 2011 vehicle prices. That finding takes into account both the higher purchase price of an electric vehicle and the lower fuel costs over the vehicle’s life. Source: CBO. Click to enlarge.

Study concludes significant additional transport policy interventions will be required for Europe to meet its GHG reduction goal

Green Car Congress

Existing fleet and vehicle withdrawal were estimated using fleet data by vehicle location and age, and vehicle age-dependent retirement curves. They then estimated emissions based on fleet composition. They then posited a range of new policies to demonstrate a range of possible fleet outcomes: R&D only.

IEA technology and policy reports outline paths to halving fuel used for combustion-engined road transport in less than 40 years

Green Car Congress

The policy package includes a new fuel economy readiness index, which measures the extent to which countries have implemented steps that will fully exploit the potential of existing fuel economy technologies and maximise their use in vehicles. Fiscal measures can have a strong influence on vehicle-purchasing behavior.

Meanwhile, significant gains in vehicle fuel economy over the coming decades are possible and very much needed globally in order to address pressing issues of climate change, energy security and sustainable mobility. The global vehicle fleet is predicted to double by 2050 with 80% of that growth in the developing world. per liter ($0.26/gallon
