Fuel, SUV's and Global Warming
During the last decade, the automotive industry and many environmental agencies, such as the EPA and Friends of the Earth, have been involved in a heated debate over the regulation of emissions standards from light-duty trucks (SUV’s). While the Friends of the Earth, an international environmental activist organization that uses grassroots techniques, has worked hard to get the federal government to raise fuel economies and emission standards for SUV’s, the automotive industry has been more than willing to produce mass quantities of gas guzzling machines. According to the EPA and other environmentally concerned groups, without tighter federal government regulation of greenhouse gas emissions from SUV’s

For example, according to the EPA, the nitrous oxide released froman SUV traps 270 times more heat per molecule in the atmosphere than carbon dioxide(1). When nitrous oxide increases in the atmosphere, more heat is trapped in the atmosphere and unnecessarily contributes to the earth’s natural greenhouse effect.
While standards have been developed to curb these emissions since 1970, it wasn’t until 1993 that standards were placed on evaporative emissions for light-duty trucks as well as tailpipe emissions. Evaporative emissions were suspected as being equally responsible for contributing to the increased amount of hydrocarbons and oxides of nitrogen in the atmosphere. According to an article in Atmospheric Environment:
Evaporative emissions are divided into five types: Diurnal, which are the emissions when the vehicle is at rest which occur due to ambient temperature changes over a typical 24-h period; Hot soak, which is driven by residual engine heat once a warmed-up engine is parked and the engine is shut off; Running loss, which occur when the vehicle is being driven; Resting loss, which is the constant at rest evaporative emissions; Refueling loss, which is the displaced vapors and drippage resulting from refueling(²).
Better technology has been developed to test levels of evaporative emissions since 1993. Now the test uses a method known as the
With the automobile, came one of the most widely used technologies in the world, the invention of the internal combustion engine which has left a noticeable impact on many parts of today’s world. One of the most widely debated and controversial topics having to do with the automobile is its effect on the environment. Al Gore, former United States Vice President and Nobel Peace Prize award winner, has spent many years trying to argue the negative effects that the internal combustion engine leaves on our planet. In his presidential campaign in 2000, he preached the ideas of a cleaner environment and better ways of living. He said, “When we seek to artificially enhance our capacity to acquire what we need from the earth, we do so at the direct expense of the earth’s ability to provide naturally what we are seeking. We frequently ignore the impact of our technological alchemy on natural processes. When we manufacture millions of internal combustion engines and automate the conversion of oxygen to CO2, we interfere with the earth’s ability to cleanse itself of the impurities that are normally removed from the atmosphere.” He has led many people to believe that the automobile of today is leaving a terrible and lasting effect on the earth’s atmosphere, and that it is one of the primary causes of the term “Global Warming.” Although Gore has had a giant following and
“We can break our dependence on oil…and become the first country to have one million electric vehicles on the road by 2015,” President Obama said in his January 2011 State of the Union address (Institute for Energy Research 1). While this may sound promising, the practicality and merit in achieving this goal remains unclear. Auto manufacturers have been working on plans for electric cars for years, especially the three largest companies in the US: Chevrolet, Chrysler, and Ford. These companies have been hoping that the development of electric cars would create a sort of lifestyle change for consumers, both weaning the U.S. off of its dependence on foreign oil and breathing life into the market for auto sales at the same time. Electric cars are often sold as zero emissions, but technically that is only true once they are charged and in terms of their tailpipe emissions. After all, they have to get their energy from somewhere and, more often than not, the electricity used for charging is supplied by traditional coal fired power plants. The real question then is whether the source and amount of energy required to build and supply an electric car with power is actually cleaner and more economical than a traditional combustion automobile. As it turns out, the answer is both unexpected and fairly complicated. In order to assess whether the use of
The number one reason why electric cars became popular is the ability to reduce the air pollution. According to the U.S. Environmental Protection Agency (EPA) almost 30% of greenhouse gas emissions are caused by transportation and most of them could be reduced by driving electric cars. The UK Department for Transport divides vehicle emissions in two categories: direct and life cycle. Direct emission are created by burning fuels while driving on the road. Petrol, diesel, and other alternative-fuel engines produce very high amounts of gases, that not only have impact on our health, but also on climate change. Gases like NO or CO2, that are known for causing many different respiratory illness. There is an estimate of 29,000 deaths a
“1 gallon of gas =24 pounds of global warming emissions” (UCSUSA). Many of the people in our world today don’t understand just how much The Automobile affects us, our lives, and the world we live in. Undoubtedly, the invention of the car has changed our perspective on the different technology created over the past years. However, cars are some of the leading factors towards one of the largest ongoing problems occurring in our world today. That problem goes by the name of global warming. “Since 1990, Transportation has been one of the fastest growing sources of U.S. GHG” (U.S.D.T), otherwise known as Greenhouse gasses. In which most of us know; global warming affects our health, environment, weather, and ultimately our lives. It is a
ACTIVITY 1 – Briefly discuss the 4 different methods of determining Scope 1 Emissions and why the first method is most appropriate for QEH.
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
White’s main points relate to the automotive revolution. Environmentalists want car companies to determine how to make alternatives to the regular petroleum-fueled engine. White explains alternative methods that could persuade the automotive industry to go green, such as using ethanol or other biofuels to power one’s car (332). However, while explaining
The burning of gasoline by automobiles releases carbon dioxide and other types of air pollution
First of all, hybrids produce 0% emissions from the tailpipe, while a car that uses gasoline produces tons of
Pursuant to energy efficiency policies, controversy swirls as climate changes are experienced in the U.S. and around the globe. When energy efficiency steps are put into place, economic outlooks turn positive. Obama’s policymaking in this arena makes “critical investments in advanced vehicle and fuel technologies, public transit, and high speed rail” (United Press International). With new fuel efficiency standards that will improve fuel economy by 2025, and other initiatives that he enacted, “12 billion barrels of oil will be saved and American consumers will save $1.7 trillion at the pump, and greenhouse gas emission standards for commercial trucks, vans, and buses for are projected to save over 500 million barrels of oil and save vehicle owners and operators an estimated $50 billion in fuel costs” (United Press
Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for
Clean Air Act, 42 U.S.C. § 7401 et seq. -- Enforced by US EPA --
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.
There is a serious problem facing the world right now. It is air pollution. The number one contributor to this epidemic is automobile emissions. We have all heard of the issues that are involved with air pollution including the depletion of the o-zone layer, the green house effect, and acid rain. The problem has been scoped from every imaginable angle, and now it is time to solve the problem. I propose that each of the ‘Big Three’ (Ford, General Motors, and Chrysler) car manufacturers be required to have 10% of their product line as EV’s By the year 2010. I propose this because it will be the start of cleaner air, EV advancement, and awareness of EV’s and how they work.
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).
