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.
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.
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]
These subsidies reduce the cost of Zero-emissions vehicle and as a result increase demand. By incentivizing consumers to reduce their purchases of petrol vehicles in favour of electric cars, there is a decrease in negative externalities associated with emissions.
It uses tiers to identify emission standards for cars, trucks and other motor vehicles. [8] In 2014, the EPA published its "Tier 3" standards for these vehicles, which tightened air pollution emission requirements and lowered the sulfur content in gasoline. [9] EPA has separate regulations for small engines, such as groundskeeping equipment.
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)
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 health of a mother directly affects the fetus during pregnancy. High levels of pollution where pregnant women reside can have adverse health effects on fetuses. Previous studies have found correlations between exposure to vehicle pollutants and certain diseases such as asthma, lung and heart disease, and cancer among others.
