A Brief Note On Pollution Across The World

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

Chapter 6, “The Burden of History: Expectations Past and Imperfect” from Kirsch’s book, The Electric Vehicle and the Burden of History, focuses on the problem of automobiles in the modern day. Kirsch states that internal combustion engines release greenhouse gasses, which harm the environment. Each individual contributes to air pollution

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”,

Cars and truck account for 20% of all U.S. global warming emissions, where more than 24 pounds per gallon of carbon dioxide and other global warming gases come right out of the car’s tailpipe (“Union of Concerned scientists”). This frightening statistic is part of the reason why the federal government has put in place many policies and incentives such as the Clean Air Act, The National Program for greenhouse gas emissions, Catalytic Converter Federal Laws, and incentives of $12,000 in California to get people to upgrade to more fuel-efficient cars. With such programs and incentives put in places, it is also important that car companies such as Toyota and Ford also take action to further cut pollution rates. They have done so by

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

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

In the article, “ Why the Gasoline Engine Isn’t Going Away Anytime Soon,” Joseph B. White writes about the reality of the old school, yet productive ways how the internal-combustion engine is going to stay in the competitive market. While at the same time he describes the change for the industry is coming just at a gradual slow pace. For years environmentalists and energy saving specialists could not accomplish what high oil prices did in just a couple years. Changing the game of auto makers focus to make improvements to their engines. The idea of changing from oil to electricity is possible but there is few chances of it succeeding until the future. The author states that cars powerful enough to serve more than one function are the basic need

Since Henry Ford’s invention of the moving assembly line to mass produce civilian automobiles in 1913, the environment and air that we breathe every day is being ruined and polluted. Though people drive cars around every day with no worries, they still are damaging the world around them with every mile. Car emissions are causing multiple issues with the air and water sources. Harmful gases are being emitted from the cars and are messing up the natural gases already present in our atmosphere. These gases consist of sulfur-based substances and are polluting and contaminating the already present nitrogen oxide and other greenhouse gases up in the atmosphere. These harmful emissions then seep into our blue seas and clear lakes, poisoning the waters and killing the

Planet earth has been around for 4.5 billion years, as landscapes such as glaciers covered large parts of the earth. Humans have been on earth for about 200,000 years, causing all sorts of changes to the environment. Humans have constructed a new earth as; roads, bridges, canals, and shelter have been built throughout the planet. This takes a toll on earth, but climate change has never been a real topic being debated, until the late 20th century. As time goes on, new inventions are being constructed such as the automobile. The first gas-powered automobile was built in 1886 (N/A). As the years progressed, the automobile became a necessity, as almost every family owned one. The United States was booming after the industrial revolution, factories were made producing all sorts of new inventions. Little did humans know, these factories and automobiles were producing all sorts of greenhouse gasses causing harm to the earth. Climate change is a topic that is grasping attention throughout the planet, as humans are now seeing the consequences of these actions.

There are new technologies in automotives out there now. For example, there is the electric car. The only problem with this is that the car needs to be plugged in and can only run for four to six hours at a time, making it hard for long distance travel. Another example is a vehicle that uses a combination of a gasoline and electric engines. They call it a hybrid electric vehicle (HEV). This particular vehicle used no gas while idling and the gasoline engine turns off while the vehicle is stopped. As a result, this vehicle uses less gasoline and the tank lasts longer. The electric motor boosts acceleration so not as much gasoline is used. The HEV has a regenerative braking system that recharges the battery. This vehicle emits half of what an ultra low emission vehicle does, so is much better for the environment. It is already possible that by the year 2003 this type of vehicle will cost less because of various state and national tax incentive plans to lower the cost significantly. This has already been accepted in Maryland

Vehicle are one of the lead contributors to air pollution; in the United States transportation causes seventy five percent of carbon monoxide (Brinson). The author Linda Brinson states “the U.S. has thirty percent of the world's automobiles, yet it contributes about half of the world's emissions from cars” (Brinson). Also, air pollution poses a serious threat to human health; it ranges from birth defects to lung diseases like tuberculosis. According to the Urban Environment Unit “urban air pollution is linked to up to one million premature deaths and one million pre-native

bikes, trains, or to carpool to go to work or to school. This is a big threat

Since the industrial revolution, the environment has gotten contaminated with carbon dioxide, the product of any combustion reaction. For many years a lot of improvement has been made in order for big industries to release less harmful gases to the atmosphere. Since 2012 the number of electric cars roaming around the world have quadrupled. This growth is linked to subsidies offered by different governments in order to reduce greenhouse gas emission. These cars are popular in many places like Norway, Quebec, and California. Recent ads suggest shifting to these cars due to their “zero emission feature”, since they run on electricity, their engine doesn’t have a combustion reaction and no carbon dioxide gets released. While it’s true that the act of driving one of these cars doesn’t contaminate the environment, there’s other factors to consider for if this transition is really all that beneficial like the media claims.

The auto industry is a very important part of our culture. Vehicles are used to get people from place to place in a timely manner. Without cars, we would be reduced to walking, riding, bicycles, or even using animals. Cars are a necessary evil because we use them in our everyday lives; however they contribute greatly to pollutants being released into the environment. U.S. companies along with the Environmental Protection Agency (EPA) have been working to find solutions to this problem. With the 253 million cars and trucks on U.S. roads, having an average age of 11.4 years, the auto industry must find ways of making cars more environmentally friendly (Hirsch, 2014).

 It wasn’t until the early 1970’s that car manufacturers saw a need to restrict the pollutants from their automobiles.  Thus came the advancements of new emission controlling components in the vehicles.  There was the catalytic converter which changed carbon dioxide into carbon monoxide, this change still resulted in pollution but significantly decreased the harm done.  Next came EGR which is Exhaust Gas Recirculation and forces unburned gas from the exhaust back into the engine making the car far more fuel efficient and environmentally friendly.  Unfortunately the next thing to follow was a serious toning down of the power of the engines.  The earlier thoughts were that bigger and more powerful were better, however these types of cars sent pollution caused by automobiles into an exponential growth.  The internal combustion engine vehicles that are on the road right now account for the vast majority of the air pollution around the world.  The electric vehicles, however, have zero emissions.  If this proposal is passed, then the condition of the urban airways will be
