Automakers would need to meet a new test simulating a head-to-hood impact and reduce the risks of serious-to-fatal head injuries in impacts at vehicle speeds of up to 25 mph (40 km/h), which ...
Green public transport vehicles including electric trains, trams and electric buses combine the advantages of green vehicles with those of sustainable transport choices. Other transport choices with very low environmental impact are cycling and other human-powered vehicles, and animal powered transport.
Emission test results from individual vehicles are in many cases compiled to evaluate the emissions performance of various classes of vehicles, the efficacy of the testing program and of various other emission-related regulations (such as changes to fuel formulations) and to model the effects of auto emissions on public health and the environment.
Harmful pollutants to the health and the environment include particulates (), hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen.Although not considered emission pollutants by the original California Air Resources Board (CARB) or U.S. Environmental Protection Agency (EPA) definitions, the most recent common use of the term also includes volatile organic compounds ...
