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 explores impact of changing gasoline and diesel taxes in Europe

Green Car Congress

Recent work from the French transport accounts commission confirmed previous results of the French Ministry for Sustainable Development: gasoline is overtaxed, and diesel fuel is undertaxed. A scheme including a decreased gasoline tax could bring about an increase in CO 2 emissions.

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 model also includes representation of fleet turnover, and opportunities for fuel use and emissions abatement, including representation of electric vehicles. Emissions trading or a carbon tax is going to achieve their emissions goals at the lowest possible cost to society. Paltsev, S., Henry Chen, YH., Karplus, V.

It also discusses fuel taxes and prices, which affect both travel and vehicle choices. While policies to promote lower carbon car choices can have an immediate effect on new car sales it takes time for the vehicle fleet to turnover, so short run impacts on transport emissions are modest. But there is a bigger picture.

Global Fuel Economy Initiative Releases Roadmap Report on Achieving 50% Fuel Economy Improvement in LDV Fleet by 2050

Green Car Congress

The International Energy Agency (IEA) has estimated that fuel consumption and emissions of CO 2 from the world’s cars will roughly double between 2000 and 2050. Their share will fall to just under 40% by 2050, with aviation set to grow to match road freight at around 22% of fuel consumption and emissions each. Fuel taxes.

They estimated the number of new vehicles required and the adoption of new technologies and fuels based on their availability and cost effectiveness under projected scenario variables such as fuel price. They then estimated emissions based on fleet composition. This step was iterated with an estimation of demand changes.
