In many cities around the world, two- and three-wheel vehicles are the main mode of personal and commercial transportation. Motorcycles are cheaper to own than cars and often more convenient to navigate on congested roadways. Unfortunately, emissions from two- and three-wheelers have long been uncontrolled. The explosive growth in motorcycle usage in Asian cities and around the world has resulted in a significant deterioration of urban air quality.
Demonstrates a linear-model approach to estimating fuel economy in trucks and buses.
An independent review of approaches to evaluating heavy-duty vehicle fuel use.
Provides background information on U.S. heavy-duty vehicle fleet characteristics and identifies issues relevant to the design and implementation of fuel economy and GHG regulations.
Updates the ICCT 2004 Status Report on MMT, providing more detail on recent studies of the potential health impacts associated with its use.
Compares passenger vehicle greenhouse gas and fuel economy standards from eight major countries, states, and regions. It finds that Japan and Europe are closely tied in the "race to the top" for the world's most efficient new passenger vehicle fleet, while the United States lags behind these two regions by a large margin.
Contrary to widespread belief, many technologies that increase fuel economy have no effect on vehicle safety. Similarly, a number of safety measures have no effect on fuel consumption.
Identifites options for regulating emissions from ships, one of the world's largest and fastest growing sources of air pollution. The regulation of commercial marine vessels represents a significant political and legal challenge, as ships operate largely outside of national boundaries and are typically owned and operated by companies based in a number of different countries.
Non-petroleum based fuels can have several advantages over gasoline and diesel in terms of energy diversity and security, control of greenhouse gas emissions, and reduced pollutant emissions. But in order to reap these benefits, care and attention must go into the production, distribution, and use of these fuels.
Summarizes the direct health effects of the fuel additive methylcyclopentadienyl manganese tricarbonyl, as well as its effects on air quality through diminished engine performance and damage to pollution control devices.
