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.
This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide. [3] [4] Within the transport sector, road transport is the largest contributor to climate change. [3]
Reducing Black Carbon Emissions from Heavy Duty Diesel Vehicles and Engines Working to reduce the climate and health impacts of black carbon and particulate matter (PM) emissions, particularly in the transport sector. A Green Freight Call to Action was issued in late 2013. Mitigating Black Carbon and Other Pollutants From Brick Production
Oxidation of hydrocarbons (unburnt and partially burned fuel) to carbon dioxide and water: C x H 2x+2 + [(3x+1)/2]O 2 → xCO 2 + (x+1)H 2 O (a combustion reaction) The two-way catalytic converter is widely used on diesel engines to reduce hydrocarbon and carbon monoxide emissions. They were also used on gasoline engines in American and ...
Section 202(a)(1) of the Clean Air Act requires the Administrator of the EPA to establish standards "applicable to the emission of any air pollutant from…new motor vehicles or new motor vehicle engines, which in [her] judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare" (emphasis added). [3]
[114] [115] A comprehensive analysis found that plant based diets reduce emissions, water pollution and land use significantly (by 75%), while reducing the destruction of wildlife and usage of water. [116] Environmental footprint of 55,504 UK citizens by diet group (Nat Food 4, 565–574, 2023).
How does a 10-year-old recycle? By using excess pieces of paper, felt and pipe cleaners and used pieces of cardboard for his school projects
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 ...
