# Carbon Credits How to Calculate

11/13/2014 9:39 PM

I have searched the net, government sites even David Suzuki: The problem!! I know that one ton or tonne of carbon dioxide = one carbon credit. Now suppose that I removed from the atmosphere some carbon dioxide and stored it in a container how do I calculate the one tonne factor. I assume the pressure it is stored in makes a difference. No place to date can I find any charts or figures on how they calculate a tonne of co2. Lets assume I had a large compressed gas cylinder such as is used in welding and captured CO2 at 2000 PSI. How many tonnes. Or a large container like a tank car and captured it under 50 PSI. What constitutes one tonne of CO2. Thanks for the help and moving me to a higher level..

Wouldn't it be stored in "the cloud"? That seems to be where Bill Gates, Google and the NSA is storing all this stuff now.

I think you're missing the point. brush up on cap and trade

I have but I have not seen a manner of determining just what a tonne consists of. It is difficult I think to weigh it as in using scales. Assume you had a chimney and you captured the co2 then sequestered it lets say underground as they are doing i western Canada how to you figure in the one tonne. There must be some volume at a certain pressure? For me 5 hrs over a week could not find anything to explain this. I have used compressed gas most of my working life and most is measured in Cubic feet or something and usually starts at a certain pressure in a container. Thanks for your comments.

CO2 can be liquified and stored at room temperature. It's done in fire extinguishers all the time. It weighs about 70 lb/cu ft at room temperature.

Weigh the container before and after.

One tonne of CO2 can be visualized by this cube 27' on each side....

A balloon a little over 30' in diameter....

"At standard pressure and 15 °C (59 °F) the density of carbon dioxide gas is 1.87 kg/m3 (0.1167 lb/ft3)..."

"We could roughly estimate the volume of 1 ton of gas by using the ideal gas equation: PV = nRT (where P is the pressure in atmospheres, V is the volume in liters, n is the number of moles = mass in grams/molar mass of the gas, R is the gas constant = 0.08206 L.atm/K.mol, T is the temperature in Kelvin). "

At STP one gram-mole of any gas occupies 22.4 litres, according to my chemistry textbook, and a gram-mole of CO2 weighs 44gm. The rest of it is simple arithmetic, Mildred.

Don't forget that PV = nRT

Use Pv=RT at gaseous compression, by the time it hits its saturated curve region or boiling point use tables.

Why bother with all that? A ton is a ton is a ton.

Put your tank on a scale, open the valve and weigh it. Then fill it with CO2, close the valve and weigh it again. For the accuracy you need, the difference in weight will be the weight of the CO2.

Wouldn't the tank have to be weighed with a total vacuum...? How would you weigh this...↓

No, it wouldn't have to be measured in a vacuum. With the tank valve open air pressure is the same inside and out. The weight is just the weight of the tank.

He uses a set of truck scales to make the weight measurements. Since he's capturing a ton of CO2 the simplest way to know he has a ton is to weigh it, and he's going to need a large set of scales. So he loads the tank on a flat bed truck. (He weighs the truck ahead of time, too, if he needs to.)

That's a good answer. If someone wants more information on C02, why not just consult the CO2 Bible, Al Gore's textbook 'Earth in the Balance'?

It's based on how much you produce (diesel engine, boiler, burner, etc ). Check out the AP-42 to calculate for each source. It's something that has to be done in order to aquire air permit from an agency.

Cap and trade basicly allows companies to pay different agencies to be a loud to product tons of emissions per year beyond the limits of the permit that is issued. The emissions include PM 10, PM 2.5, NOx, SOx, CO, COx, and HAP. Every state has there own version for several years the Feds are just starting with their project the last couple of years.

Stop thinking that CO2 is poison.

I do not recall mentioning that CO2 was poison but I do view it as a source of potential income in the future based entirely on the carbon credit scenario.

Indeed! Thanks for the honesty.

CO2 is a source of income and revenue. That's all.

No CO2 , no potential for oxygen, from plants and trees--One of the balancing factors that is conveniently ignored..During the warming stages of the planet (which was actually much shorter that the cooling periods), CO2 turned the planet into a Botanists' dream, and oxygen flowed like liquor at a Las Vegas wedding.. One of the biggest problems the planet has is DEFORESTATION.. Which affects the amount of living trees, shrubs, and the like, to assimilate CO2 , and let us breathe...

THe last year I was in PA for the mining company I worked for I was able to sell 450 tons of combined air pollutants in the market at \$2500 a ton. Not bad profit for reducing the emissions at my sites for one year.

Carbon Credits are kind of like our current "fiat money" we use, or like a Bitcoin. There is no value except that someone says something has value. Our "notes" that we use for currency isn't backed by anything as it used to be, i.e. gold or silver.

It's like Genghis Khan taking over a country and making some sort of coinage and saying it had value. In his case it was because his authority substantiated the coinage and it was the only thing that could be used officially.

In the case of Carbon Credits, it is nothing but a scam and money making idea fabricated by some ingenious scoundrel to fleece people out of their money.

I understand that ISIS will be issuing their own currency.. I suspect that dealing directly with one of these brutes would be dicey…..
