Environmental regulations in developed countries have reduced the individual vehicle's emission. However, this has been offset by an increase in the number of vehicles, and increased use of each vehicle (an effect known as the Jevons paradox). [3] Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. [5]
Carbon monoxide is harmful because it reduces oxygen delivery to the body's organs and tissues. It is most harmful to those who suffer from heart and respiratory disease. [4] Carbon Dioxide: Carbon dioxide is one of the most prominent greenhouse gasses emitted by motor vehicles. In 2006, 23.6% of the total inventory of U.S. greenhouse gasses ...
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, [1] or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe , flue gas stack , or propelling nozzle .
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines. The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
The new rules, which take effect for model years 2027 through 2032, will avoid up to 1 billion tons of greenhouse gas emissions over the next three decades and provide $13 billion in net benefits ...
EPA's greenhouse gas score [28] reflects the amount of greenhouse gases a vehicle will produce over its lifetime, based on typical consumer usage. The scoring is from 0 to 10, where 10 represents the lowest amount of greenhouse gases. The Greenhouse gas score is determined from the vehicle's estimated fuel economy and its fuel type.
General Motors will pay nearly $146 million in penalties to the federal government because 5.9 million of its older vehicles do not comply with emissions and fuel economy standards. The National ...
About 16% of manmade carbon dioxide is from road transport, [17] mostly passenger vehicles. [18] Gasoline cars with less than two passengers produce more carbon dioxide per passenger kilometer than any other form of land transport. [19] The changing speed of a vehicle is a factor when considering the measurement of greenhouse gas emissions ...
