Sources of carbon dioxide emissions can be either human-caused or natural. Natural sources of the emissions are beyond the control of the human beings. However, manmade sources are caused or attributed directly or indirectly to the human action. Most of the products’ production processes in the market use a source of energy that involves emission of the carbon dioxide into the environment.
Therefore, the actual producers of the carbon dioxide and the users of the consumer products whose production entails emissions are related directly and indirectly respectively ('Carbon dioxide emissions rise to record levels', 2008). Production processes that contribute to the production and emission of carbon dioxide are; energy generation from coal and natural gases, transportation (using motor vehicles, shipping & air travel), cooking heavy construction, mining, heavy construction etc. all the production process account for the majority of the products that are used by the average person.
Energy generation in the most parts of the world entails burning of some fossil fuel. As a result, there are many carbon emissions resulting from this process. 87 percent of the world is responsible for energy generation using the fossil fuels ('Trapping and keeping carbon dioxide emissions', 2013). In order to generate the energy, fossil fuels are subjected to combustion process at high temperatures whereby there is combination of the carbon part of the fossil fuel with oxygen from the air to form carbon dioxide.
Generation of electricity uses coal to produce heat, which is then used to boil water to produce steam. The steam is produced at a high pressure. For a reason it is ideal for turning turbines, which in turn generate electric ('Low-carbon footprint', 2011). All forms of energy that come from burning of fossil fuels such as coal and a natural gas are sources of carbon dioxide that is emitted into the environment. In some cases, there are backup generators that are used to produce energy during the power outages. Backup generators are designed to use either gas or gasoline. Both are fossil fuels and their combustion releases carbon dioxide into the environment.
The actual production of the fuels is another source of emissions. In the oil mining process, natural gas is usually located at the top of the oil deposits due to its less viscous nature. This aspect makes it the first one to escape. Some of the mining fields have oilrigs that are not well equipped to tap the gas ('Trapping and keeping carbon dioxide emissions', 2013). As a result, they burn it as it comes out to avoid its escape into the environment.
Burning of the excess natural gas creates two predominant issues. The miners can let it escape into the environment and avoid the burning process ('Low-carbon footprint', 2011). Alternatively, they can burn it. Letting the gas escape is precarious given that the gas is a more potent as a greenhouse gas than carbon dioxide. Burning it is the lesser evil of the tow since there is chance of cleaning up the environment using plants ('Trapping and keeping carbon dioxide emissions', 2013). Therefore, the use of electricity produced from fossil fuels contributes to the emissions into the environment.
Transport sector is the second leading source of emissions. In the sector, almost all the main means of movement rely on the combustion of one fuel or the other. Fossil fuels used in the shipping, air and motor travel account for a significant part of the individual carbon print. Every person relies on one mode of transport in one way or the other. In the transportation of major bulky goods, the shipping mode is preferred ('Low-carbon footprint', 2011). Most of the ships use diesel as the main source of fuel for the engines and other electricity generators. Due to the high carbon content in this fuel, the major shipping lines are responsible for the most carbon emissions in the transport sector. Use of any mode of transport increases the carbon print. Domestic use of natural gas for cooking and heating in cold places accounts for the majority of the individual’s carbon prints.
