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]
United States vehicle emission standards are set through a combination of legislative mandates enacted by Congress through Clean Air Act (CAA) amendments from 1970 onwards, and executive regulations managed nationally by the Environmental Protection Agency (EPA), and more recently along with the National Highway Traffic Safety Administration (NHTSA).
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.

Less known fact when considering measurement of emissions is how it changes with changing speed of vehicle. Traffic congestion is dangerous because of its effects on society. Besides increasing risk of injuries arising primarily from high-grade roads together with the high noise, the main consequence of traffic congestion is increasing level of ...
Usage of electric cars damages people’s health and the environment less than similar sized internal combustion engine cars. While aspects of their production can induce similar, less or different environmental impacts, they produce little or no tailpipe emissions , and reduce dependence on petroleum , greenhouse gas emissions , and deaths ...
Many of these pollutants contribute to environmental degradation and have negative effects on human health. To prevent unnecessary damage to human health and the environment, environmental regulatory agencies such as the U.S. Environmental Protection Agency have established policies to minimize air pollution from mobile sources.
