A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are constructed.

Researchers at the Georgia Institute of Technology have developed a strategy to capture, store and eventually recycle carbon from vehicles to prevent the pollutant from finding its way from a car tailpipe into the atmosphere. Georgia Tech researchers envision a zero emission car, and a transportation system completely free of fossil fuels.

Nissan Motor Co. Ltd. announced today an additional new service for its popular CARWINGS navigation system. In line with the objectives of the Nissan Green Program 2010 to reduce carbon-dioxide emissions, they will be introducing a new service dubbed “Eco-Drive and You” (Anata mo eco-drive) to promote “eco-driving” habits in Japan.

in a significant move towards reducing CO2 car emissions as well as particles pollution, the Renault-Nissan Alliance and Project Better Place engage in a breakthrough with electric vehicles in Israel.

A CSIRO report released today confirms that using pure biodiesel or blending biodiesel with standard fuel could reduce greenhouse gas emissions from the transport sector.

Ford Motor Company is rolling out a range of global environmental technologies that will provide customers more fuel-efficient vehicles that emit fewer greenhouse gases without compromising their expectations for safety, interior room or performance, Alan Mulally, the company’s president and chief executive officer, announced today.

Children who carry variations in specific genes that metabolize vehicle emissions are more susceptible to developing asthma, particularly if they live near major roadways, a study led by researchers at the University of Southern California (USC) suggests.

Nissan Motor Co., Ltd. today announced that a new clean diesel technology using high-performance catalysts shows great promise and may be able to meet the State of California's standard for super-ultra-low emission vehicles (SULEVs), equivalent to the Tier2Bin2 emissions requirements.

In future drivers may only have to glance at the dashboard to see the pollution spewing out of their vehicle’s exhausts.

A long-term Georgia Institute of Technology study continues to validate the effectiveness of Georgia's vehicle emissions inspection program in 13 metro Atlanta counties that are part of a federal ozone level non-attainment area.

As concerns over global warming continue to increase, the automotive industry is facing tremendous pressure to reduce vehicle emissions such as nitrous oxide (NOx), carbon dioxide (CO2) and particulate matter (PM) because of the harmful effects of these gases on the environment.
