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.
Mobile source air pollution includes any air pollution emitted by motor vehicles, airplanes, locomotives, and other engines and equipment that can be moved from one location to another. Many of these pollutants contribute to environmental degradation and have negative effects on human health.
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.
Changes designed to encourage people in Paris to take other forms of transportation have contributed to a 40% decline in air pollution, according to city officials.
A low-emission zone (LEZ) is a defined area where access by some polluting vehicles is restricted or deterred with the aim of improving air quality.This may favour vehicles such as bicycles, micromobility vehicles, (certain) alternative fuel vehicles, hybrid electric vehicles, plug-in hybrids, and zero-emission vehicles such as all-electric vehicles.
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.
Government statistics reveal little change in health-harming particulate matter in 2022.
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
