Three quarters of emissions in 2004 were coming from road traffic (Woodcock, p.1930, 2009). Emissions used from transportation are forecasted to increase from the year 2007-2030 by about 80% according to studies done by James Woodcock who is currently studying climate change and health from car fuels (Woodcock, p.1930, 2009). This is due to the fact that the emissions from vehicles are increasing significantly and are higher than any other energy fragment (Woodcock, p.1930, 2009). The only way to lower this percentage is to decrease the number of individual automobiles on the road and increase the number of public transit systems, starting long distance walking to work or school, carpooling or even biking to destinations. These principles would

The U.S government has been actively involved in overseeing emission standards for years. This corresponds with the statement made by the U.S Department of transportation that, “Transportation is the largest end-use sector emitting CO2”, and also the statement released by the NRCAN in which, “Fuel usage & carbon dioxide emissions have grown steadily over the past two decades.” These factors are only to be associated with your average four door sedan and/or light truck. These do not include your 18 wheelers, heavy trucks, or the gas guzzling vans that emit more carbon dioxide into the air and are also on the road more today than ever have been before. Cars are readily and easily obtainable more so now than ever have been. This creates more fuel to be burned up in which produces more toxins to be constantly released into the atmosphere. In fact, according to Scientific American “cars relate as much as 30 gallons of GHG, while only driving 3 miles.” These miles can be correlated with something just as simple as your average work commute. According to the United States Census Bureau, “Nearly 600,000 full-time workers had "megacommutes" of at least 90 minutes and 50 miles.” Those workers alone would each be releasing up to 500 gallons of GHG. These can be considered some of the bigger factors that the greenhouse gasses have taken a toll on.

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

New York City has unique benefits in that there are tremendous amounts of people who live within close proximity to each other. This has resulted in higher uses of mass transit systems (such as: subways and buses). On average, New York’s total environmental footprint is 7.1 metrics tons per person annually. This is much lower than national average of 24.5 metric tons. The city contributes 1% of the total amount of greenhouse gases emitted into the atmosphere for the United States each year. (“Inventory Greenhouse of New York City,” 2007) (Jarvey, 2006)

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

Coal-burning power plants are the largest U.S. source of carbon dioxide pollution producing 2.5 billion tons of CO2 emissions every year (Natural Resources Defense Council 2005). Cars are the second largest source, creating nearly 1.5 billion tons of CO2 annually (Natural Resources Defense Council 2005). Approximately 50% of the greenhouse gasses causing global warming are coming from burning fossil fuels to power or create electricity and another 25% was coming out of our tail pipes from burning gasoline or diesel (Brunsaw 2015).

On average, an American commuter spends around 30 hours per week sitting in traffic going to and from the job that they may or may not love. Commuters in some cities like Washington DC, that is both near and dear to our hearts, can spend roughly 60 hours per week stuck in traffic. Not only is time wasted wasted while commuting, but the gas that we constantly fill our cars up with may as well be flushed down the drain. Following the gas that is going down this metaphorical drain here, is a ridiculous amount of money from an innocent commuter’s wallet. Additionally, time wasted while commuting could’ve been time well spent with one’s family or even with one’s pets. The

In 2012, transportation accounted for 19% of the total global energy consumption, 96% of which was produced by fossil fuels [1, p. 201]. Furthermore, air transport is the most carbon intensive mode of transportation, accounting for approximately 10 times more carbon emissions than road transport and 100 times more than shipping (per tonne km) [2, p. 4].

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

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.

In addition, these six counties had at least one or more code red days per year, when air pollution has reached unhealthy and harmful levels for everyone. These six counties, Rockdale, Fulton, Gwinnett, Henry, Cobb, and Rockdale, all lie the nearest to the city of Atlanta, an intersection of interstate highways. Though many culprits contribute to this hazardous level of air pollution in the Atlanta Metropolitan Area, cars contribute so much more because of the sheer amount of cars that exist in the Atlanta Metropolitan Area. An average car can emit 6 tons of carbon dioxide per year, and assuming that the every adult has a car that does not run on electricity in Metro Atlanta’s population of 5,490,000, there would be 32,940,000 tons of carbon dioxide emitted by those cars per year. To give a perspective, the Scherer plant, a coal-fired power plant, in Juliet, Georgia gives off 25.3 million tons of carbon dioxide per year, but these estimations do not include other vehicles that emit carbon dioxide and other pollutants (Center for Global

Being lazy is a great thing because so much time is saved. Time may be saved, but in exchange, the environment gets destroyed instead. Driving a car to work may be faster, but it also destroys the environment so much faster. Biking to the store serves the same purpose and it saves the environment greatly. Cars are a huge contributor to global warming. Cars and trucks combined are responsible for one-fifth of all US emissions. They release about 24 pounds of carbon dioxide and other global warming gases for every gallon of gas used (Union of Concerned Scientists). About five pounds of those gases come from production, extraction, and delivery of gasoline. More than 19 pounds are released per gallon from a car's tailpipe (Union of Concerned Scientists). 1.2 billion cubic yards of polluted air is from manufacture. Painting and coating cars produces 40 million pounds of air releases and 24 million pounds of hazardous waste a year. A car's lifetime produces 1.3 billion cubic yard of polluted air and scatters 40 pounds of worn tire particles, brake debris, and worn road surface into the atmosphere (Bike to Work Day). Pollutants released a year add up to over 12,140 lbs for cars and 17,000 for light trucks. Some of those pollutants are carbon dioxide, carbon monoxide, hydrocarbons, and nitrogen oxides (Bike to Work Day). By choosing to bike or walk instead of drive, the amount of gases and waste contributing to global warming, drops drastically. Choosing to drive instead of taking a greener form of transportation is a great threat to the environment.

Two main causes are burning fossil fuels and driving our cars. According to a NASA earth observatory web page, “fossil fuel burning (coal, oil and gas) releases about 6 billion metric tons per year.” On the EPA web site, it is stated that most of the emissions of greenhouse gases, “about 82%, are from burning fossil fuels to generate electricity and power our cars.” As I said before, driving our cars also is a large cause. For example, Ecobridge states that “Twenty percent of U.S. carbon dioxide emissions comes from the burning of gasoline in internal-combustion engines of cars and light trucks.” So a fair amount of the emissions is from driving your car.

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

Truck transportation has been the backbone of freight movements in the United States and across the globe for decades. While utilizing trucks is an economical way to move freight for short hauls of less than a 1,000 miles, there are high environmental and infrastructure costs for utilizing this mode of transportation. According to Lowe, road transportation’s use of energy resources rose 103 per cent in the period since 1970 (2005). Additionally, Lowe points out that road transportation’s emission of green house gasses, “increased by 76% between 1971 and 1989” (Lowe, 2005, p. 112). Furthermore, road transportation is the largest polluter in the industry. It utilizes “over 80% of the total energy used in the transport sector and contributes over 75% of its total CO2 output (Lowe, 2005, p. 113). Finally, freight transportation by heavy vehicles causes pavement damage at significantly higher rates than passenger traffic (SSTI, 2011).
