The existing literature proposes various methodologies and procedures to predict GHG emissions in the transport sector. In general, these studies utilize time series analysis, regression analysis, decomposition, and optimization models, as explained below:
• Time series analysis
(Sultan 2010) introduces the use of co-combination of pay per capita and fuel price (FP) to measure transport fuel consumption (FC), while (Bekhet, H & Yasmin 2013), (Bekhet, HA & Yusop 2009), (Ang 2008), (Ediger & Akar 2007), and (Wang, SS et al. 2011) discover a relationship between vitality utilization and CO2 discharges. (Begum et al. 2015) consider the impact of GDP, FC, and concentration of population on the CO2 emissions. (Ivy-Yap, LL & Bekhet 2015)

• Strategic planning tools
Greaves (2009) evaluates the impacts of air quality and GHG reduction using a strategic-level modeling tool that considers freight travel, the characteristics of the fleet, and the factors related to GHG and non-GHG emissions.
• Linear programming models
Researchers have also proposed a number of optimisation models to predict GHG emissions, especially from the energy sectors. (Börjesson & Ahlgren 2012), (Bai & Wei 1996), and (Wang, C et al. 2008) explore the cost-effectiveness of conceivable CO2 reduction choices for the energy industries. Furthermore, utilizing a mixed integer linear programming model, (Hashim et al. 2005) contemplate the impacts of fuel balancing and fuel switching choices on power generation. Their studies reveal that FE and fuel switching are the best choices to decrease CO2 discharges. (Tan et al. 2013) utilize mixed integer linear programming analysis to perfectly arrange waste to the level of vitality that best minimizes electricity generation costs and CO2 emissions.
Generally, after a period of time, the road transport sector’s GHG outflows demonstrate a pattern. Therefore, through the use of statistical forecasting techniques, researchers and planners can anticipate future outflows. After (Brown 1957) and
Case Background: - In transportation industry, one of the biggest challenge is how to deal with carbon dioxide emissions and how to reduce the energy. According to the Natural Resources Canada, one third of the greenhouse emission is because of transportation industry.
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
A Peer-reviewed journal, Estimation of Carbon Footprint of Fuel Loss Due to Idling of Vehicles at Signalised Intersection in Delhi confirmed my concerns relating to carbon emissions whilst idling in traffic congestion by providing the calculation of the amount of carbon emissions produced by average car using petrol. CO2 emissions from a gallon of gasoline = 2,421 grams x 0.99 x (44/12) = 8,788 grams = 8.8 kg/gallon = 19.4 pounds/gallon or litre equivalent CO2 emissions from a gallon of diesel = 2,778 grams x 0.99 x (44/12) = 10,084 grams = 10.1 kg/gallon = 22.2 pounds/gallon or litre equivalent (Bhandaria, Paridab, and Singh 2013).
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
The transport sector is one of the main global consumers of fossil fuel related energy in the world. Unfortunately fossil fuel is non-renewable source of energy and the production of oil has been fluctuating in the recent past. At the same time, combustion of petroleum related fuel release greenhouse gases such as carbon monoxide and carbon dioxide that destroy the ozone layer and result to further environmental degradation. Therefore to work
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.
Estimating future emissions is difficult, because it depends on demographic, economic, technological, policy, and institutional developments. Several emissions scenarios have been developed based on differing projections of these underlying factors. For example, by 2100, in the absence of emissions control policies, carbon dioxide concentrations are projected to be
Transportation off-site emissions are emissions that are generated from cradle to gate. The total emissions index is used to assess each alternative where overall emissions are divided into direct and indirect emissions. The direct emissions index, indirect emissions index, total emissions index and global emission index can be calculated using equation 1, 2, 3 and 4, respectively. Detailed information on calculating direct and indirect emissions can be found elsewhere (Marzouk et al., 2017).
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
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).
