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

Green Car Congress

Two new reports—one on technology, the other on policy— released by the International Energy Agency (IEA) outline pathways to improve the fuel efficiency of combustion-engined road vehicles by 50% by the middle of the century, saving as much as four-fifths of current annual global oil consumption. Technology Roadmap.

Study explores impact of changing gasoline and diesel taxes in Europe

Green Car Congress

Because diesel- and gasoline- powered cars are almost perfect substitutes for users, a change in the levels of fuel taxation is expected to affect engine type choice by households and businesses, and automakers will respond by changing their pricing strategies to maintain their profits. —Bretau and Weber.

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

Green Car Congress

Because changes in fuel economy take a long time to percolate through the entire fleet, an 18% reduction in fuel used by vehicles purchased in a given year (due to a 20% improvement in their fuel economy) would result in only about a 1% reduction of the fuel used by the entire fleet.

Vaillant and Honda present home combined heat and power system for Europe

Green Car Congress

It is the first European system with highly efficient gas engine technology for use in single-family homes. For the first time, Honda used an Extended Expansion Linkage Engine (EXLink) in its mCHP Module, helping to significantly improve the efficiency of the unit.

BCG study finds conventional automotive technologies have high CO2 reduction potential at lower cost; stiff competition for electric cars

Green Car Congress

As a result, BCG concludes, the electric car faces stiff competition from ICEs (internal combustion engines) and, based solely on total cost of ownership (TCO) economics, will not be the preferred option for most consumers. BCG finds that ICE technologies can reduce CO 2 emissions up to 40% at a cost as low as $50 per percentage of reduction.

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

Green Car Congress

Significant engineering work will needed to produce an approach that results in fuel efficiency standards that are cost effective and that accurately represent the effects of fuel consumption reducing technologies. The report finds that there is an immediate need to begin the development of such a regulatory approach.

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. An alternative to a feebate that could raise similar revenue is raising fuel taxes by around $0.07 —GFEI working paper. per liter ($0.26/gallon gallon US), according to the paper.
