How much carbon dioxide does a ton of coal produce?
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.

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.
In 1999, in the US, more than 30 percent of fossil fuel related carbon dioxide emissions were a direct result of transportation. With about two-thirds of this being from petro…l consumption by motor vehicles and the remainder coming from diesel and jet fuel use in lorries and aircraft, respectively. Worldwide, motor vehicles currently emit well over 900 million metric tons of CO2 each year. These emissions account for more than 15 percent of global fossil fuel CO2 releases.
Some buses are electric, and the CO2 emitted by their operation would come from coal fired power plants. West coast electric buses would receive hydrologic power, emitting ver…y little CO2. Most buses are diesel powered, and average about 6 mpg. Since automobiles get about 20 mpg, a bus needs to carry 4 passengers to break even. More than that and the bus gains in efficiency over the typical passenger automobile. One gallon of fuel emits close to 20 pounds of CO2, even though the fuel itself weighs only 6.25 pounds. This is because the carbon in the fuel combines with oxygen in the air--a LOT of it. So 20 pounds per gallon times a gallon every six miles equals 3.3 lbs per mile. The US Federal Transit Authority estimates each bus averages 37,000 miles per year. So that amounts to 123,000 lbs (62 tons) of CO2 per bus per year. For the next part of the question we need to know how many buses there are. There are 450 to 480 thousand school buses in the US (close to half a million). The US probably has fewer buses per capita than most nations on earth, which rely more heavily on public transportation.
Man, and all animals, breathe out carbon dioxide, but that is part of the natural carbon cycle, and that carbon is removed just as regularly. Apart from the carbon cycle, ma…n releases about 29 billion tonnes of CO2 a year, mostly from burning fossil fuels and cement production. This works out at 79,452,000 tonnes every day (nearly 80 million tonnes or 88 million US tons). A: The average American uses enough energy to release about 50,000 pounds of carbon dioxide per year. That's about 140 pounds a day for one American. That is the proposed major contributor to global warming. There are many small inexpensive steps that each person can do that will help bring these totals down. But, it needs to be a group effort. As the problem is a group problem! A: Well for every 1 gallon of gas consumed it produces 19 pounds of co2, given the fact that in America alone we burn 400,000,000 gallons of gas a day. that comes to 7.6 billion pounds of co2 emitted into the atmosphere each day by Americans alone.
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.
CH4 --> CO2 is a 1 to 1 reaction (C-balanced) when burning with oxygen. So 1 mole CH4 --> 1 mole CO2 So 1 Litere CH4 --> 1 Liter CO2 So 16 grams CH4 --> 44 grams CO2…
Coal and wood actually produce fairly similar amounts of carbon dioxide when burnt. However, the carbon dioxide produced from the wood originally came from the atmosphere and …was converted by the original tree into wood - so burning the wood simply returns this to the atmosphere and there is no net increase in the amount of carbon dioxide in the atmosphere. When we burn coal, the carbon dioxide is produced from carbon that had been sequestered underground for millions of years, so by this means we do add new carbon dioxide to the atmosphere.
A flat, geometric plane produces no CO2. However, most aircraft burn carbon based fuel, and the combustion of this fuel releases carbon dioxide. A small Piper Club will burn… about ten gallons per hour, releasing close to 200 pounds of CO2. A commercial 747 typically burns about 3600 gallons of fuel per hour, liberating 34 tons of CO2.
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.
The oceans contain 37,400 billion tons (GT) of suspended carbon, land biomass has 2000-3000 GT. The atmosphere contains 720 billion tons of CO2 and humans contribute 40 billio…n tons per year. The oceans, land and atmosphere exchange CO2 continuously so the additional load by humans is small, on an annual basis. Over the past century humans have, however, raised atmospheric CO2 levels from 290 ppm to nearly 400 ppm. At the present rate we will pass 500 ppm before 2050, an increase of nearly 60%.
Approximately 3 % of our carbon dioxide is formed by aircraft. See appended link for per plane calculation.
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.
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.
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.
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.
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.
