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

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. Worldwide, cars currently account for close to half of the transport sector’s fuel consumption and CO 2 emissions. litres per 100 km).

GFEI report suggests $2T savings from fuel economy improvements in ICE vehicles through 2025 can help fund long-term transition to plug-ins

Green Car Congress

Increasingly efficient conventional combustion-engine vehicles will be key in moving towards a low carbon future, according to the GFEI. The global vehicle fleet is predicted to double by 2050 with 80% of that growth in the developing world. Thus a $500 tax would still allow consumers to keep 3?4

National Research Council Report Explores Improving Fuel Economy of Medium- and Heavy-Duty Vehicles; Recommends Immediately Beginning Developing a Regulatory Approach

Green Car Congress

The National Research Council has released a prepublication edition of a new congressionally mandated report that evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles (MHDVs), such as tractor-trailers, transit buses, and work trucks.

CEPS task force report identifies tightening emissions standards as key policy to hit EU 60% reduction in transport GHG; full life-cycle emissions optimal metric

Green Car Congress

The report argues that the biggest component of total transport reductions could come from more energy-efficient vehicles, combined with the gradual introduction of low-carbon fuels and new engine technologies. Eco-driving and efficient transport systems could provide for the other—much smaller shares—of reductions.
