- The largest source of CO2 emissions globally is the combustion of fossil fuels such as coal, oil and gas in power plants, automobiles, industrial facilities and other sources.
- A number of specialized industrial production processes and product uses such as mineral production, metal production and the use of petroleum-based products can also lead to CO2 emissions.
- Carbon sequestration is the process by which growing trees and plants absorb or remove CO2 from the atmosphere and turn it into biomass (e.g., wood, leaves, etc.). Deforestation, conversely, can lead to significant levels of CO2 emissions in some countries.
- Carbon dioxide can be captured from power plants and industrial facilities before it is released into the atmosphere, and then injected deep underground.
The figure below displays a breakdown of sources of CO2 emissions in the U.S. in 2006. By far the largest source is fossil fuel combustion:

What does the burning of fossil fuels release into the carbon-oxygen cycle?
Carbon dioxide (CO2).
The primary products of complete combustion of fossil fuels are?
The primary products of the complete combustion of fossil fuels is: CARBON DIOXIDE and WATER.=)
Do fossil fuels contribute to the carbon dioxide and oxygen cycle?
yes
What do fossil fuels give out when they are burnt?
Carbon dioxide and carbon monoxide to name but a couple of gasses.
When fossil fuels are burned carbon dioxide and water are produced what elements must be contained in fossils fuels?
hydrocarbons( carbon and hydrogen)
Is carbon dioxide released by fossil fuel formation?
No, formation of fossil fuels (coal, oil and natural gas) removes carbon dioxide from the atmosphere.Burning of fossil fuels releases carbon dioxide.
What energy source causes carbon dioxide?
Burning any of the fossil fuels (coal, oil and natural gas) releases carbon dioxide.
By what process is the carbon in fossil fuels released into the atmosphere?
Burning of the fossil fuels releases the carbon dioxide.
What process is the carbon in fossil fuels released into the atmosphere?
Burning of the fossil fuels releases the carbon dioxide.
How does burning less fossil fuels reduce the amount of carbon dioxide being released into the atmosphere?
When you burn fossil fuels to make enrgy, carbon dioxide is released. So, if you burn less fossil fuels, less carbon dioxide is released.
What causes carbon dioxide?
fossil fuels and breathing causes carbon dioxide :)
What is alternative fossil fuels?
Fossil fuels come from fossilied plant matter in the ground. Alternative fuels are alternatives to fossil fuels, and these are mainly carbon fuels that take their carbon from carbon dioxide in the atmosphere (as fossil fuels do) but on a carbon cycle with a much shorter term. An example is wood, which can be burned as more trees are growing and absorbing carbon dioxide.
How does burning fossil fuels affect the concentration of carbon dioxide in the atmosphere?
The burning of fossil fuels affects the concentration of carbon dioxide in the atmosphere by increasing it.
What provide more carbon dioxide than any other source?
Fossil fuels (coal and methane)
Is the role of fossil fuels in the carbon cycle?
The role of fossil fuels in the carbon cycle is to produce carbon dioxide. Fossil fuels are considered to be the highest contributors to pollution of the environment.
What is the relationship between burning of fossil fuels and carbon dioxide?
Burning fossil fuels (combustion) releases carbon dioxide. As carbon dioxide is a greenhouse gas, presently contributing to global warming, this is why the world is moving away from fossil fuels to renewable energy.
What are the past benefits of fossil fuels?
Fossil fuels (coal, oil and natural gas) were a very valuable source in past, before we realised the effects of their carbon dioxide emissions.
