According to Energy Information Administration (EIA) research, emissions range from 2,791 lbs per short ton for lignite coal to 5,685 lbs per short ton for anthracite coal. However, the coefficients for the coals that are primarily used in electricity production, bituminous and sub-bituminous are 4,931 and 3,716 respectively. See the EIA related link for more information.

A gallon of gasoline releases 14 lbs of CO2 when burned. A car that averages 20 miles per gallon and is driven a typical 15,000 miles per year will burn 750 gallons, emitting …a little over 5 tons of CO2. A typical automobile emits about six tenths (0.6) pounds of CO2 per mile driven.
Carbon dioxide is usually measured in kilogrammes or tons. But at standard temperature and pressure, one cubic metre of carbon dioxide weighs 1.83 kilogrammes. So a ton of car…bon dioxide occupies 546 cubic metres, which is a cube 27 ft by 27 ft by 27 ft.
Burning one kilo of carbon releases about 3.6 kilos of carbon dioxide. Carbon has an atomic weight of 12. Oxygen has an atomic weight of 16. The oxidation of carbon results …in carbon dioxide, atomic weight 44. So 44/12 is 3.667. There are other things in coal besides pure carbon, slight impurities, so in general 1 kg of coal releases about 3.6 kg of CO2.
The formation of carbon dioxide. Burning coal that releases only carbon dioxide means the coal is completely burnt and more energy is produced. Carbon monoxide is released w…hen the combustion process is incomplete.
Approximately 3 % of our carbon dioxide is formed by aircraft. See appended link for per plane calculation.
Coal is the largest contributor to the human-made increase of CO2 in the air. In terms of carbon dioxide emissions, coal is slightly ahead of petroleum and about double …that of natural gas.

An airplane produces about 2 kg of CO2 for every liter of fuel burned. The calculations for each type of aircraft are shown t the Link.
The oceans are regarded as carbon dioxide sinks, not sources. This means they remove carbon dioxide, not produce it. Carbon dioxide dissolves from the air into ocean water. On…ce there it is removed by plankton and algae, by corals and mollusks in making shells, and by chemical action.
You get a tonne of carbon dioxide for every 300 kg. or so of carbon you burn. This could come from 400 liters of automotive fuel, 300 kg. of coal, 500 kg. of dry wood or 1000 …m 3 of gaseous fuel.
About 7 billion tons of coal is presently mined each year. While some of this is used to make coke for steel blast furnaces, most of it ends up being burned in coal power plan…ts. Coal is carbon twelve, but during oxidation it combines with diatomic oxygen (O16) to form CO2. In other words, one ton of coal releases over 2.8 tons of CO2. World wide, nearly 20 billion tons of CO2 is emitted by coal fired power plants each year, at the present time. As China and other nations continue expanding coal production, this is expected to rise a little bit in the ensuing years.
Assuming you mean "how much carbon dioxide is generated by the electricity consumption of a computer", you are actually asking a very complicated question. In the first inst…ance, you need to know what the energy consumption of your/the average computer is. This depends on a huge number of factors such as: how powerful the processor and graphics cards are, how many hard drives and optical drives it has and what kind of monitor it has and what size that is. Also, the consumption varies depending on whether the computer is under load (performing calculations and reading from or writing to hard drives or optical media). If you're not interested in accuracy, I would guess about 200W for a modest office machine rough average. Next, it depends on how much CO2 is produced per unit of electricity from your supplier. This in turn depends on what sources are used to provide your energy. Coal and oil produce more CO2 than gas, nuclear and others. The calculation is likely to be very complex and require a lot of research. The answer could be in the region of 500g per KWh, but this could vary wildly depending on which country you are in. So taking our two assumptions (0.2KW and 500g/KWh), we can very roughly estimate 100g of CO2 produced per hour of computer usage.
Some animals produce different amounts of carbon dioxide. insects, use 6 billion metric tons. humans, use only about 2 million metric tons. I bet another animal has 4 million …metric tons, and another probably has 7. There you go. Answered.
'Is carbon dioxide produced by burning' carbon rich compounds in an oxygen rich environment, I'm only going to give you one guess at this - better make it a good one!
