Study finds CO2 emissions trading more effective path to automotive CO2 reduction in Europe than tailpipe standards

Green Car Congress

The goal of this paper is to assess the resulting CO 2 emissions, energy, and economic impacts of the EU CO 2 mandates, and compare them to an alternative scenario where vehicle emissions are part of an emission trading system designed to meet Europe’s announced economy-wide targets.

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. per gallon or higher.

CO 2 emissions from transportation sector by scenario in the study. The economy-wide CO 2 prices applied increase the cost of driving only marginally with respect to the business-as-usual case. Fuel prices above $8/gallon may be needed to significantly reduce US GHG emissions and oil imports. Source: Morrow et al.

users pay for the construction and maintenance of roads via a federal fuel tax. Revenues from the tax go into the federal Highway Trust Fund, which is independent of the General Fund; every five years or so Congress passes an authorization bill to allocate these revenues. States use similar mechanisms. —Huang et al.

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.

MIT Energy Initiative report on transforming the US transportation system by 2050 to address climate challenges

Green Car Congress

More research, development, and demonstration studies are needed to lay the foundation for such a long-term transformation. There are many options available for reducing the fuel, energy, and GHG emissions impacts of LDVs. miles per gallon will not reflect what most new car buyers should expect to achieve in 2025.
