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]
Less CO 2 emissions than fossil-fuelled cars, thus limiting climate change [8] As almost all electric cars have regenerative braking brake pads can be used less frequently than in non-electric cars, and may thus sometimes produce less particulate pollution than brakes in non-electric cars.
Additionally, as car tires wear down, they shed the materials they are made of into the air as particulate pollution. [10] Those pollutants are known to cause various respiratory and other health issues and cars are among the leading cause of smog in modern developed world cities.
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.
U.S. Environmental Protection Agency estimates of average passenger car emissions in the United States for April 2000 [3] Component Emission Rate Annual pollution emitted Hydrocarbons 2.80 grams/mile (1.75 g/km) 77.1 pounds (35.0 kg) Carbon monoxide 20.9 grams/mile (13.06 g/km) 575 pounds (261 kg) NO x: 1.39 grams/mile (0.87 g/km)
The modern negative associations with heavy automotive use include the use of non-renewable fuels, a dramatic increase in the rate of accidental death, the disconnection of local community, [3] [4] the decrease of local economy, [5] the rise in cardiovascular diseases, the emission of air and noise pollution, the emission of greenhouse gases ...
Numerous states have emissions-testing programs to limit pollution from on-road vehicles, such as cars and light-duty trucks. Each of these vehicles must meet specific emissions targets before being allowed to obtain or renew vehicle registrations. Many of these programs are administered on the local and county level.
A green vehicle, clean vehicle, eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels.
