Phase-out of fossil fuel vehicles is a critical component of a shift to sustainable transport; Motor vehicles driven by fossil fuels, a key factor in urban air pollution, can be replaced by electric vehicles. Even in emission-free electric vehicles, rubber tires produce significant amounts of air pollution themselves, ranking as 13th worst ...
The California Air Resources Board found in studies that 50% or more of the air pollution in Southern California is due to car emissions. [ citation needed ] Concentrations of pollutants emitted from combustion engines may be particularly high around signalized intersections because of idling and accelerations.
Each of these vehicles must meet specific emissions targets before being allowed to obtain or renew vehicle registrations. Many of these programs are administered on the local and county level. For example, the Clean Air Car Check is a vehicle emissions-testing program for all vehicles registered in Lake and Porter counties in Indiana. The two ...
EPA staff project that the new rule will lower carbon dioxide emissions by about 7.2 billion metric tons, while also cutting thousands of tons of other air pollutants.
The road haulage industry is contributing around 20% of the UK's total carbon emissions a year, with only the energy industry having a larger contribution, at around 39%. Road haulage is a significant consumer of fossil fuels and associated carbon emissions – HGV vehicles account for almost 20 percent of total emissions. [35]
It is the only U.S. state with the power to request a waiver from the EPA to set its own, more stringent, vehicle emission regulations because it has struggled with some of the nation's worst air ...
Haagen-Smit also discovered that these air pollutants react with sunlight to form ozone, a major component of smog. As a response to this situation, the California Air Resources Board (CARB) was established in 1967 with Haagen-Smit as its first chairman. CARB set stringent vehicle emission standards to reduce air pollution in the state.
Car pollutants include carbon monoxide, nitrogen oxides, particulate matter (fine dusts and soot), and toxic air pollutants [1] While these pollutants affect the general health of populations, they are known to also have specific adverse effects on expectant mothers, their fetuses and children.
