Car Emissions and Global Warming Essay

We all know that the Global Warming is a serious issue to be addressed. This is the right time to realize the importance of eco-friendly products to save the earth from global warming and its ill effects. Unfortunately the automobile emissions are the second largest contributors for the green house gases.

The second largest source of greenhouse gas emissions in the United States is related to transportation, the burning of oil to produce energy in a combustion motor. The combustion process inside of engines is what produces the carbon matter that is emitted into the air through the exhaust system on gas-powered vehicles. Gas-powered transportation is accountable for 24 percent of the global carbon emissions; this should not come as much of a surprise given the amount of urban sprawl that is being seen in the United States and across the globe. In the past decade, the Environmental Protection Agency, the United States government, and major car manufacturers have been working in conjunction to find ways to provide a “greener” form of transportation (EPA, 2011). This has included testing the use of hydropower, ethanol, natural gas, biodiesel, and electricity as a means of powering vehicles, which has led to the introduction of hybrid vehicles. Hybrid vehicles run on electricity and gasoline, the byproduct of oil that is generally used in the engine combustion process of vehicles (U.S. Department of

First, cars pollute the environment. In 2012 the EPA reported that a whopping 28% of emissions came from transportation. As it says in the article “Running off the Road”, by Grover Kingsley, “With their largely petroleum based fuel, cars constantly spew carbon monoxide into the air.” We are responsible for the

Every day, millions of Americans turn on the engines of their cars and drive to school or work. What these people do not realize is that the vehicles they operate greatly pollute the planet. According to the Environmental Protection Agency’s recent website post, “Environmental Impacts from Automobiles”,

Climate change and transportation play a big role and it is important to be concerned for our future generations. The use of gasoline cars is a major producer in carbon dioxide emissions, although they are not entirely responsible for it—they play a role in it. Other form of transportations like buses and taxis also contribute to carbon dioxide emissions. The total amount of carbon dioxide emissions from an average car is seventy six percent which comes from usage of a vehicle containing gasoline. Efficiency has increased by twenty percent in regards to electric motors, especially when it comes to their wheels using no power when the car is at rest. Car ownership will increase and with this, improvements in technology could be a vital

Even if a vehicle can realistically maintain the doubled MPG standard, it is touted to save 2 million oil barrels per day or 84 million gallons per day. However, this only accounts for only a conservative 25% of the total 8.774 million barrels or 368 million gallons of gasoline consumed per day (USDOE). At the heart of this law is the cutting of 6 billion metric tons of harmful greenhouse gases over the lifetime of the program. Some may state that any decrease in greenhouse gases is a step forward. Either way, the typical passenger vehicle emits 4.7 million metric tons of harmful greenhouse gases per year (Greenhouse gas emissions). Considering the overall benefit of cutting out 6 billion metric tons, it is equivalent to taking 1,276 passenger vehicles off of the road. According to the USDOT, there were 253,639,386 registered vehicles on the road in 2012, which would reduce the amount of vehicles on the road by .0004% by the end of this

While new trucks and cars emit about 90 percent fewer pollutants than they did 30 years ago total annual vehicle miles driven have increased by more than 140 percent since 1970 and are expected to increase another 25 percent by 2010. The emission reductions from individual vehicles have not adequately kept pace with the increase in miles driven. As a result cars and trucks are still the largest single

According to Huffington Post, there are over a billion cars on the road every day. This contributes to the major cause behind global warming; Carbon Dioxide. In 2012, approximately 35.599 billion metric tons of Carbon Dioxide were spewed into the air. That is 61% higher than in the 1990s. If this rate of carbon dioxide emission is not drastically reduced, the melting of Earth's ice sheets will not only contribute to increasing temperatures but threaten all of mankind. On March 18, Carbon Dioxide levels have for the first time

Over time vehicles have become a gigantic cause of pollution and global warming. As years have passed by vehicles have been designed to be environmentally friendly. This is only happening for the vehicles that are everyday vehicles. Most of those vehicles are still not fully efficient due to the inability of affording a new car. Racing in the biggest thing that is in need of finding a way to limit it to release less pollution.

Transportation is the number one thing we consumers do that harms the environment. Transportation causes the highest amount of environmental damage overall - nearly half of the toxic air pollution and more than a quarter of the greenhouse gases traceable to household consumption. Over time, however, sales of trucks, vans and SUV's went from 16% market share to over 50%. One big auto manufacturer even shelved their work of the last three years, spent updating their most popular selling economy car, so they could spend the money getting SUVs to market faster.

Climate change occurs mainly because of human activities, such as harvesting resources, industrialization, and technological invention, among other factors. One of the main reasons climate change has occurred in the last a few decades is because conventional cars which made their first appearance in 1886, have become increasingly popular. Although, conventional cars are more efficient and less expensive than hybrid cars, hybrid cars help reduce the negative impact on the environment more than conventional cars. A Hybrid car has disadvantages due to the battery and power of the engine, which has to improve over time, which makes people less likely to buy hybrid cars over conventional cars in the present such as gas and diesel. Even though both conventional and electric cars have negative impact on the environment, they have different scale of impact on the environment. By looking at how each system of both types of cars work, what the effect on fuel consumption rate and greenhouse gas emissions are, and what the disadvantages of electric cars are compared to conventional cars, hybrid electric cars are less likely to negatively impact on the environment more than conventional cars.

What has changed in the last few hundred years is the additional release of carbon dioxide by human activities. Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of U.S. carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. In 1997, the United States emitted about one-fifth of total global greenhouse gases.

In this research paper I will explore the effect on the environment of the anthropogenic emissions of greenhouse gases emitted by modes of transportation. My first angle will expose how automobiles release harmful toxins. My second angle will reveal how the running of trains has a negative impact on the environment. My third angle will disclose how the flying of airplanes has a detrimental effect.

Greenhouse gases come from such mainstays of modern life as electrical power plants, automobiles, and heavy industry. Growing consumption of fuel by less efficient cars and light trucks suggests that motor vehicles may soon overtake industry as the largest source of gases suspected of causing global warming by effectively creating a greenhouse around the Earth. Many people do not want to decrease their standard of living by reducing their consumption of fossil fuels. These people do not realize that if they reduce their consumption, there will be a reduction in the amount of greenhouse gases. If this does not happen and global warming continues, the long-term effects may be catastrophic.

Automobiles are a major producer of greenhouse gas. One gallon of fuel burned puts five pounds of carbon dioxide into the atmosphere. Let’s say that an average car gets 25 miles to the gallon, and that car has a ten gallon tank. Every time a car gets filled up with gas, another fifty pounds of carbon dioxide have been put back into the atmosphere, and that is just one car. The automobile industry is very important to the world economy, so I am not saying that we should stop making cars, but there are other solutions. The recent trend of hybrid electric cars that get up to fifty miles to the gallon are becoming more popular. Also public transportation is very important. City dwellers that live downtown, do not need to drive their cars to work. Every major city has a form of public transportation that can get anyone around the city, and for that gallon of gas a bus burns the same five pounds reaches the atmosphere, but instead of one
