Good Car – Bad Car

Car Pollution

Good Car – Bad Car

More likely than not, getting a car from point A to point B involves combustion of a fossil fuel, a process that emits gas and affects the environment. It begs the question: how does car contamination affect the environment and the ozone layer? In accordance with the U.S. EPA, more than 50% of the air pollution in a modern country is caused by mobile sources, mainly automobiles. Further contributing to the contamination potential of vehicles is the fact that they’re filled up with numerous fluids, which can damage the environment in the cases of leakage or improper disposal.

So how does Vehicle Emissions and Air Quality relate:  When a vehicle’s engine is running, several various kinds of gasses and particles are emitted that may have detrimental effects on the environment. Of particular concern to the environment is CO2, a greenhouse gas, hydrocarbons, any of more than a dozen volatile organic compounds, some of that are known carcinogens, nitrogen oxides, sulfur oxides, and particulate matter, tiny particles of solids, like metal and soot. Other emissions which affect human health and create smog include ozone and carbon monoxide. The great news is that despite the increase of vehicles on the road, air quality today is, in fact, better than it was in the 70s, thanks to the 1970 Clean Air Act.

Vehicle emissions may affect the environment in a number of ways. The emission of greenhouse gasses, like CO2, contribute to global warming. Some air pollutants and particulate matter from vehicles can be deposited on soil and surface waters where they enter the food chain, these materials may affect the reproductive, respiratory, immune and neurological systems of animals. Nitrogen oxides and sulfur oxides are mainly responsible for acid rain, which modifies the pH of waterways and soils and may harm the organisms that rely on these resources.

The ozone layer can help to defend life on earth from the suns ultraviolet rays, but human activities have contributed to the accelerated exhaustion of this protective shield. Substances that contribute to ozone depletion typically have high concentrations of chlorine or bromine atoms and include chlorofluorocarbons, or CFCs, halons, methyl bromide, carbon tetrachloride and methyl chloroform. Vehicle emissions contain few chlorine- or bromine heavy materials, and for that reason have little impact on ozone depletion.

Conclusion: Try to avoid fossil fuel transportation in your business. You’ll score much lower in term of carbon footprint.
