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're 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.
Emissions from road dust suspension depend on a vehicle's speed, size, shape, porosity, amount of dust on road surfaces, and weather conditions. Considerable uncertainty remains regarding the amount of PM emitted by non-exhaust sources in real-world driving conditions and how this amount varies with the abovementioned factors.
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 ...
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 Clean Air Act of 1963 (CAA) was passed as an extension of the Air Pollution Control Act of 1955, encouraging the federal government via the United States Public Health Service under the then-Department of Health, Education, and Welfare (HEW) to encourage research and development towards reducing pollution and working with states to establish their own emission reduction programs.
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)
