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]
With the intention of correcting the positive externality that electric vehicles contribute to the environment. This has been implemented through the use of tax credits, purchase rebates, and tax exemptions. [28] These subsidies reduce the cost of Zero-emissions vehicle and as a result increase demand. By incentivizing consumers to reduce their ...
The Federal Aviation Administration, for example, establishes standards to limit emissions from aircraft, whereas the U.S. Department of Transportation and Environmental Protection Agency administer various aspects of on-road vehicle fuel economy regulations. On the state level, mandatory vehicle emissions-testing programs are often required as ...
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.
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)
Temperatures in Illinois are projected to rise over the course of the 21st century. The amount of increase depends on how much humans curtail their CO 2 emissions. If humans continue to emit at current levels, the increase will be between 8 and 14 °F (4.4 and 7.8 °C). If emissions are lowered, the rise will be between 4 and 9 °F (2.2 and 5 °C).
Harmful pollutants to the health and the environment include particulates (), hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen.Although not considered emission pollutants by the original California Air Resources Board (CARB) or U.S. Environmental Protection Agency (EPA) definitions, the most recent common use of the term also includes volatile organic compounds ...
