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.
Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. [5] Energy use and emissions vary largely between modes, causing environmentalists to call for a transition from air and road to rail and human-powered transport, and increase transport electrification and energy efficiency.
Citizens living in car-dominant highly populated areas are at the risk of health issues caused by these pollutants, ranging from chronic cough to death. According to Singh, the groups of people most affected by air pollution include children, people suffering from an underlying chronic disease, the asthmatic, and elderly.
“The No. 1 contributor to climate change is transportation emissions, so everyone we can get out of a gas-powered car and traveling by metro or foot or bike is a hugely important way to help ...
Compared to conventional internal combustion engine automobiles, electric cars reduce local air pollution, especially in cities, [50] as they do not emit harmful tailpipe pollutants such as particulates , volatile organic compounds, hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen.

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. External costs which can arise from using cars and trucks in ...
