Electric vehicles (EVs) coupled with low-carbon electricity sources offer the potential for reducing greenhouse gas emissions and exposure to tailpipe emissions from personal transportation. In considering these benefits, it is important to address concerns of problem-shifting. In addition, while many studies have focused on the use phase in comparing transportation options, vehicle production is also significant when comparing conventional and EVs. We develop and provide a transparent life cycle inventory of conventional and electric vehicles and apply our inventory to assess conventional and EVs over a range of impact categories.
The path to sustainable mobility is complex, with numerous competing and complementary approaches to alternative energy sources, production, distribution and applications; fuel and power-train options; materials; safety, economic and environmental considerations and trade-offs; policy issues; and different timelines for research, development and deployment.
Green Car Congress’ mission is to provide timely, high-quality editorial about the full spectrum of energy options, technologies, products, issues and policies related to sustainable mobility.
1) To provide timely and accurate reporting and analysis of relevant developments around the world.
2) To take the panoptic view, providing comprehensive coverage and the context critical to understanding and evaluating emerging energy options.
U.S. passenger vehicles are one of the largest contributors to global warming pollution, responsible for roughly a quarter of annual U.S. energy-related emissions of CO2.
Better transportation choices can have an enormous impact on climate change. With our membersâ€™ support, UCS spearheads research that finds new and better ways to reduce harmful vehicle emissions.
Biodiesel is the first and only alternative fuel to have a complete
evaluation of emission results and potential health effects
submitted to the U.S. Environmental Protection Agency (EPA)
under the Clean Air Act Section 211(b). These programs include
the most stringent emissions testing protocols ever required by
EPA for certification of fuels or fuel additives. The data gathered
complete the most thorough inventory of the environmental
and human health effects attributes that current technology will
Biodiesel is a clean burning alternative fuel, produced from
domestic, renewable resources such as plant oils, animal fats, used
cooking oil and even new sources such as algae. Biodiesel contains
no petroleum, but it can be blended at any level with petroleum
diesel to create a biodiesel blend. Biodiesel blends can be used
in most compression-ignition (diesel) engines with little or no
modifications. Biodiesel is simple to use, biodegradable, nontoxic,
and essentially free of sulfur and aromatics.
The NLE currently posts 2048 CRS Reports on environmental and related topics. The Congressional Research Service (CRS), part of the Library of Congress, prepares its reports for the U.S. Congress. CRS products undergo review for accuracy and objectivity and contain nontechnical information that can be very useful to people interested in environmental policy. CRS does not itself provide these documents to the general public. Although CRS documents are prepared specifically for Congress and not widely distributed, their distribution is not protected by law or copyright. NCSE is committed to expanding, maintaining and updating its database of reports, making them available and searchable for the public.
The new technologies presented here by Valeo confirm the appropriateness of the companyâ€™s strategy to develop global solutions which improve safety, comfort and driving pleasure while at the same time reducing fuel consumption and pollutant emissions.
Changes in Gasoline III is the latest in the ongoing series of Changes in Gasoline manuals. The
first manual, entitled Changes in Gasoline & the Automobile Service Technician, was originally
published in 1987. Over a four year period it was periodically updated to focus on fuel related areas
of greatest interest to automobile service technicians. The first version of the manual achieved a
circulation of 345,000 copies.
Hydrogen is the third most abundant element on the earth’s surface, where it is found primarily in water (H2O) and organic compounds. It is generally produced from hydrocarbons or water; and, when burned as a fuel or converted to electricity, it joins with oxygen to again form water.
Biodiesel (fatty acid alkyl esters) is a cleaner-burning diesel replacement fuel made from natural, renewable sources such as new and used vegetable oils and animal fats. Just like petroleum diesel, biodiesel operates in combustion-ignition engines.
