  2. Health and environmental impact of transport - Wikipedia

    en.wikipedia.org/wiki/Health_and_environmental...

    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]

  3. Health and environmental effects of battery electric cars

    en.wikipedia.org/wiki/Health_and_environmental...

    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 ...

  4. Vehicle emissions control - Wikipedia

    en.wikipedia.org/wiki/Vehicle_emissions_control

    The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides. Starting in the 1950s and 1960s, various regulatory agencies were formed with a primary focus on studying the vehicle emissions and their effects on human health and the ...

    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 ...

  7. Every car has an optimal speed range that results in minimum fuel consumption, but this range differs between vehicle types, design and age. ... (and therefore emissions) by driving more smoothly ...

  8. Mobile source air pollution - Wikipedia

    en.wikipedia.org/wiki/Mobile_source_air_pollution

    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. Similar ...

  9. United States vehicle emission standards - Wikipedia

    en.wikipedia.org/wiki/United_States_vehicle...

    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).
