Air Pollution and Automobiles Essay

The automobiles that we trigger off in everyday play a vital role in our lives. They get us or so from match slight place to virtu altogethery opposite on a daily basis. The U. S. Environmental security measure Agencys (EPA 2010) some(prenominal) studies constitute that exhaust electric arcs from these vehicles be the sum one ambiance pollutant in the get together States. origin contamination causes many an(prenominal) incompatible issues that affect personal surfaceness as healthy as environmental f recreateors. Over the classs many different studies shed been practise by different people and agencies showing how reduce song contamination from automobiles can only derive the globe.The g everyplacenment has been one of the largest advocates of abaseing emissions from automobiles. Because lush exhaust emissions created by automobiles is a major factor in transfer contaminant, the presidential term has enacted many laws and regulations limiting the co me of emissions vehicles may produce. Automobiles argon a major cause of air defilement around the world. As the tot of vehicles on the alley increases, the occur of emissions from these vehicles increases. As of 2003 Leslie Miller shows that the (World Almanac 2003) describe that there were to a greater extent than 107 million households by dint ofout the joined States (U.S. ) Leslie calculateed that the situation of Transportation statistics show that there are roughly 204,000,000 vehicles registered in the U. S.That produces a ratio of 1. 9 autos to 1. 8 people per household in the U. S. The enactment of vehicles registered in the U. S. has been doubling every five forms. If this trend continues as it has over the past 30 divisions, by the year 2030 there exit be approximately 1,200,000,000 (1. 2 Billion) vehicles producing some type of hepatotoxic emission into our earths atmosphere. The vehicles that we drive produce many different toxic gasses affecting our eart h negatively.These emissions affect our environment and damage the greenhouse operation. The greenhouse effect is the wreak in which infrared rays are emitted from the sun into the earths atmosphere trapping heat that keeps the earths temperature in a habit subject range. Toxic gasses from our automobiles released into the atmosphere do much damage to this inborn process. As the gasses release, the atmosphere impart deteriorate which grants the earths affectionateness temperature to rise. This process causes difficulty in farming as well as the melting of the polar ice caps virtually flooding the earth slowly. coulomb Dioxide (CO2) is the most emitted gas into the atmosphere. The Environmental resistance Agency (2010) shows that cars release 76% of the CO2 that is present in the earths atmosphere. For every gallon of gas used by an automobile there is approximately 20 pounds of CO2 released into the atmosphere. CO2 is a heat-trapping gas released by the combustion process b y our vehicles. (Cakmak 2006), Shows that CO2 is the largest contributing factor to the smog in passing congested areas around the U. S. The following is an emissions chart breaking d receive the de nonation of the seven most common air pollutants.As you can chit-chat high management vehicles are the largest source of air pollution in the geo graphic area of The United States. The major pollutants abbreviations are shown below and correlate with the graph that follows. Geographic Area United States Pollutant Carbon Monoxide (CO), Nitrogen Oxides (Nox), Volatile constituent(a) Compounds (VOC), Sulfur Dioxide SO2, Particulate (size 2. 5 micrometers) (PM 2. 5), Particulate (size 10 micrometers) (PM 10), or ammonium hydroxide (NH3) pic Emissions by Category Chart (Environmental Protection Agency, 2002).The exhaust systems on our vehicles too produce another pollutant cognise as hydrocarbons. Hydrocarbons are produced by our vehicles when can molecules in these vehicles do not fully burn and then travel through the exhaust system. In addition to these deadly hydrocarbons, Nitrogen Oxide (Nox) is another large contributor of air pollution in the U. S. today. The EPAs (2010) studies colligate approximately 30% of the NOx in the atmosphere to the vehicles on the road in the U. S. today. NOx has been linked by studies to the formation of acid rainwater in our in our environment.Simply said the reduction of vehicle emissions will cause the amount of greenhouse gasses emitted into the atmosphere to lower creating less negative effects on our earths environment and our health. Cakmak, Dales and Jedek (2006) says that air pollution has many negative effects on the environment as well as our personal health. many a(prenominal) respiratory issues come from breathing in the gasses released from automobiles. CO2 affects us by lowering the amount of oxygen our parenthood can carry throughout our bodies causing death in some cases. duck soup pollution is linked to lung cancer as well as lower birth rates that are common among people in cities that record higher(prenominal)(prenominal) vehicle registrations. The EPA has shown that these cities are at a higher risk for many health issues. Children residing in areas with higher concentrations of air pollution are three to four times much likely to give voice asthmatic conditions. Automobiles are a major cause of vehicle deaths in the form of vehicular accidents. EPA (2010) statistics show that approximately 120 people are killed by a vehicular accident with distributively day that goes by. umteen environmental issues caused by automobile emissions are overlooked by the just person. The acid rain produced from vehicle emissions has caused many bad health problems for humans. stinging rain is has been shown to cause eye irritation as well as coughing as well as asthma in more extreme cases. Urban smog in addition to global warm up are the most common factors in air pollution. Smog is a prod uct of different greenhouse gasses mixing together which produces a apparent layer very close to the earths surface cognise as the ground ozone layer.The smog acts like a blanket around the earth trapping the harmful emissions allowing us to breathe them in each day. Over the geezerhood the effects of air pollution maintain been sight by many from politicians to auto manufacturers. Many within these agencies confirm worked to bowdlerise the emissions that our automobiles produce. bingle of the major changes in our society that created focus on the issues of air pollution caused by automobiles was the Clean gentle wind accomplishment of 1963. This bill was introduced to allow the government limited enforcement power over interstate pollution issues.In 1965 a Motor Vehicle Act was introduced. Melosi(2004) explains that this act allowed auto manufacturers the strength to practice stricter emission standards for new vehicles with government funding such as grants. In 1970 th e acting president of the U. S. Richard Nixon, signed an amendment to the Clean Air act enforcing stricter fuel regulations on auto manufacturers. This Act was the most stringent air pollution law ever passed in the U. S. The Clean Air Act has been revised throughout the years to conform to stricter guidelines as air pollution becomes more of an issue throughout the U.S. The Clean Air Act was not originally designed to prohibit pollution rather it was enacted to define an welcome amount of pollution allowed to be emitted from vehicles. Despite the fact that the Clean Air Act was passed there are still major issues that emissions from vehicles create including health and environmental issues. Crabb and Johnson (2010) wrote an article in The Energy Journal showing the principal(prenominal) issue that does contribute to the amount of emissions from automobiles is the fuel economy that is attained by each vehicle.The Energy Policy and Conservation Act established guidelines known as C orporate Average Fuel Economy (CAFE. ) During prexy Nixons time in office the 1975 CAFE regulations were written to require manufacturers to view as a corporate average of 18 miles per gallon (MPG) or higher starting with 1978 model year vehicles. Between 1985 and 1992 multiple adjustments were made to elucidate the cafe regulations stricter. By the mid 1990s the government increased the MPG fatality to be raised to 27. 5 MPG corporate average.As we move out front in time the regulations have only become stricter for auto manufacturers. The year 2009 brought on many new accomplishments for the U. S. in that auto manufacturers began making newer models that will take us into the following(a) decade. An article written by Tarlow (2009) shows that prexy Obama fought hard for his place in the White House, one of his main concerns existence air pollution and the amount of emissions caused by automobiles. After being pick out President Obama revealed a proposal for new CAFE regul ations that will flash back emissions and further sign the U. S.dependency on imported oil. The regulation that President Obama has proposed will require auto manufacturers to get wind the strictest guidelines for fuel economy ever. Obamas proposal will require auto manufacturers to meet a strict 35. 5 MPG by the model year 2016. The following graphs show the stripped combined miles per gallon that manufacturers are required to meet and post on the vehicles. The graphs break down different types of fuel as well as the amount of CO2 released per mile driven. Chart 1 shows the requirements prior to the EPA ever-changing the way they figure a vehicles MPG.With model year 2009 and newer the EPA became stricter when figuring MPG for different fuel types. Chart 2 reflects the new criteria with the stricter guidelines enforced. As you can see, the babys room gas (GHG) score is higher as a vehicle produces less CO2 per mile. pic Chart 1 (Environmental Protection Agency, 2010) pic Chart 2 (Environmental Protection Agency, 2010) concourse the strict guidelines does not come at zero hail. Meeting the guidelines will monetary value auto manufacturers no matter how it is broken down.The look for and development in meeting stricter regulations does have a cost attached to it. On the other end if auto manufacturers do not meet the CAFE guideline the government has allowed civil liabilities to be charged. The liabilities allowed by the government may cost manufactures approximately $5. 50 for each tenth of a mile that they are under the minimum requirement square off forth. The EPA (2010), reports that among the year 1993 and 2004, various manufacturers paid approximately $618 million in penalties. This report in any case included the fact that in the same period no Asian or U. S. manufacturers have ever been charged any penalties.Many have argued that the cost of meeting increasingly difficult fuel emissions has added cost to the bottom line value of a vehicle as well as slowing sales and potentially putting smaller car dealers out of business. Much question has been done in the area of estimating be of incorporating better emissions equipment on newer automobiles. Initially, when emission regulation were introduced in the U. S. around 1970, many manufacturers were concerned that to meet the guidelines there would need to be costly research done to meet the most cost effective practices to lower emissions.Crabb and Johnson (2010) show that many manufacturers estimated initial costs for catalytic systems designed to reduce emissions would cost approximately $3,000. The government challenged the manufacturers and discounted these findings proving that with some changes to the processes the cost can be bang down by two thirds the initial cost that was estimated. The government was sufficient to show that the systems could be incorporated on motor vehicles for about $1,300. , which is importantly less than estimated.The EPA (2010), reports that many other agencies have conducted research regarding any issues caused by stricter guidelines from the government as well as the cost factor included. The northeast States for Coordinated Air Use Management (NESCAUM) has not been able to enumeration any negative sales because of the Clean Air Act or stricter guidelines. On the contrary, they have been able to show that the sales of new vehicles have fluctuated between 13 and 17 million new vehicles each year for the past 20 years and never declining below these numbers.Much of the fluctuation has been attributed to the changing economical times throughout the history of the U. S. over the inhabit 20 years. Many believe that because diesel motor railway locomotives typically produce a higher rate of exhaust emission than gasoline engines, which may make it more difficult to purchase diesel vehicles in Clean Air States. Diesel engines are most commonly used on vehicles with a Gross Vehicle Weight Rating (GVWR) of more than 8500. The CAFE regulations do not affect the sales or use of these diesel vehicles.The more common everyday on-road use vehicles such as the GMC Sierra 2500 and 3500 serial as well as the popular Dodge beat in 2500 and 3500 serial publication vehicles are the vehicles that will feel the greatest impact on emission regulations. Passenger vehicles such as the Volkswagen Golf TDI are not shortly certified under the California Air Resources Board (CARB. ) CARB is a set of standards that the state of California has enacted to control the amount of emissions vehicles registered in the state may emit. Many states followed California in adopting these strict standards that go above and beyond the government requirements.Massachusetts, Maine, New York, New Jersey and Vermont are some of the states that have adopted CARB standards for vehicles sold in those states. As more states adopt their own standards that are stricter than government guidelines, auto manufacturers have difficulty selli ng accredited new vehicles in certain states. Many of the diesel engines used in vehicle applications do not meet the strict EPA and state regulations. In 2010 most new trucks with diesel engines will utilize Exhaust hit man Recirculation (EGR) to lower the NOx released by diesel engines by injecting a carbamide compound that breaks down the NOx.Cummins, the worlds second largest diesel engine manufacturer has met all emission guidelines that went into effect for all 2010 and newer model year vehicles since the model year 2007. This is helped to benefit sales for the companies that use the Cummins Diesel engine. One such company is Chrysler Corporation that uses the Cummins Diesel in their Dodge Ram Heavy Duty line up. Hirata shows that by using this engine Chrysler has been able to stay at the forefront in technology. As others struggle to find ways to meet regulations, Chrysler will benefit from the technology because their vehicles meet all regulations.The only change Cummins made was adding an inexpensive technology called Selective catalytic Reduction to further reduce NOx emissions into the earths atmosphere. separate manufacturers utilizing diesel engines will be developing systems that require the addition of urea at an additional cost to the customer driving consumer cost through the roof. Cummins has the advantage that the prices for their system will not fluctuate as other diesel engine manufacturers prices will increase because of the cost associated with their new technologies.To reduce the emissions throughout the U. S., not only are the government and auto manufacturers responsible, we are each individually responsible to do our part in reducing the greenhouse gasses we contribute. The manufacturer changing the design of automobile systems is a refer part in the reduction. The way we personally use our vehicles will also contribute to the reduction of greenhouse gasses. Things that can be done on our part may include reducing the allowable amount of vehicles in an area by issuing quotas and permits for different areas. Many people have looked into the use of hybrid vehicles as alternatives to fully gas or diesel powered vehicles.Lowering the personal use of our vehicles as well as participating in car pools will fully reduce the amount of green house gasses that we individually release into the atmosphere. In doing the things unavoidable to lower emission we must be proactive and take an interest in the positive things that will benefit us by reducing the amount of emissions. Although the government has worked with auto manufacturers to reduce vehicle emissions, our cars still produce toxic emissions into the air. With the increasing regulations on fuel economy we will only benefit from less emissions being released into the air.Many things may be done on a consumer level as well. We have access to alternative fuels such as E-85 (ethanol) which comes from corn as well as compressed intrinsic gas which releases very little emissions if any. The government and auto manufacturers are endlessly looking for ways to reduce emission further. As time goes on unless we completely stop using automobiles we will still be face up with the release of toxic emissions from automobile exhaust systems. The available resources will unceasingly become better as time goes on and companies create the next best thing to reduce the amount of emissions released by their vehicles.The only way to ensure that our children have a cleaner environment is by educating them with the necessary information that will allow a greener environment over the years to come.References Cakmak, S. , Dales, R E, & Judek, S.
