What does “CO2” mean?
Long story short, CO2 is one of the greenhouse gases that absorbs radiation and prevents heat from escaping our atmosphere. This excess heat creates disrupted weather patterns, higher global temperature averages, and other *ahem* changes… in the climate.
What is the equivalent weight of CO2?
– Quora. According to the definition of equivalent weight in this case the mass of carbon which reacts with 1 g of hydrogen is 12/4 = 3 there for MW/EW = 4, so the n-factor here is 4. What is the equivalent weight of CO2? One CO2 molecule is reacting with 2 hydroxyl ions. Thus n-factor is 2 and its equivalent weight is 44/2 = 22g/mole.
What level of CO2 ppm is dangerous?
Traditionally, the team say, it had been thought that CO 2 levels would need to reach a very high concentration of at least 5,000 parts per million (ppm) before they would affect human health. But a growing body of research suggests CO 2 levels as low as 1,000ppm could cause health problems, even if exposure only lasts for a few hours.
How do you calculate CO2 equivalent?
You calculate the carbon dioxide equivalent of a quantity of F gas by multiplying the mass of the gas (in tonnes), by the gas’ global warming potential (GWP)….Example calculationMass (in tonnes) of F gas multiplied by GWP of F gas.= (10/1,000) * 3,922.= 39.2 tonnes CO2 equivalent.
What is the unit of CO2 equivalent?
million metric tonnesCarbon dioxide equivalents are commonly expressed as million metric tonnes of carbon dioxide equivalents, abbreviated as MMTCDE. The carbon dioxide equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP: MMTCDE = (million metric tonnes of a gas) * (GWP of the gas).
What is the difference between CO2 and CO2 equivalent?
CO2 refers to Carbon Dioxide, while CO2e stands for “Carbon Dioxide Equivalent” which includes CO2 and other greenhouse gases. Carbon dioxide, or CO2, is a natural, colorless, and odorless greenhouse gas emitted when fossil fuels (i.e., natural gas, oil, coal, etc.)
What is 1kg of CO2 equivalent to?
This means that a quantity of CO2 can be expressed in terms of the amount of carbon it contains by multiplying the amount of CO2 by 0.27 (12/44). E.g. 1kg of CO2 can be expressed as 0.27kg of carbon, as this is the amount of carbon in the CO2.
What exactly is 1 ton CO2?
That’s equivalent to: Driving 23,000 miles in the average car (once around the world) 18 dairy cows in weight. 25 million plastic straws.
What is a metric ton of CO2 equivalent to?
2,204.6 lbsA metric ton is 2,204.6 lbs, and is a little bigger than the American ton’s 2,000 lbs and a little smaller than the British ton’s at 2,240 lbs —but the three are fairly comparable.)
Why do we use CO2e?
CO2e essentially describes the global warming potential of all greenhouse gases. In other words, the impact of different greenhouse gases is expressed in terms of the amount of CO2 that would result in the same amount of warming. Put simply, CO2e gathers all greenhouse gases into one place.
How much CO2 does 1kg of natural gas produce?
2.75 kg1 kg of natural gas releases 2.75 kg of CO2.
How many trees does it take to offset 1 kg of CO2?
In summary, it can be concluded that the annual CO2 offsetting rate varies from 21.77 kg CO2/tree to 31.5 kg CO2/tree. To compensate 1 tonne of CO2, 31 to 46 trees are needed.
How many kg are in a ton of CO2?
Tom. Hi Devesh, In terms of converting from kg to t: 1 kg = 0.001 metric ton, in other words, 1t = 1000 kg.
How do you convert CO2 to PPM?
How to convert ppm to percent concentration? When you start counting over 10,000 ppm, most scientists and manufacturers change from ppm to percent concentration. So instead of describing a 10,000 ppm CO2 sensor, we talk about a 1% CO2 sensor instead. (10,000/1,000,000 = 0.01) – the terms are synonymous.
What is the CO2 equivalent to one pound of beef?
Pound of beef produces 36 pounds of CO2 emissions.
How are CO2 equivalents calculated?
CO2 calculator uses for the calculation of CO 2 -Use scientific data from research institutes as a basis for your balance sheets. Use for example this CO2 calculator of the Federal Environment Agency to find out the climate impact of your personal, everyday behavior based on CO2 equivalents.
Why use CO2 equivalents?
Climate change is the biggest environmental problem of our time – but is not based exclusively on our CO2 emissions. With nitrous oxide and methane, there are two other gases that are much more harmful to the climate, which are due to our behavior and remain in the atmosphere longer. Below I have listed the most important climate gases:
What is CO2 equivalent?
A carbon dioxide equivalent or CO2 equivalent, abbreviated as CO2-eq is a metric measure used to compare the emissions from various greenhouse gases on the basis of their global-warming potential (GWP), by converting amounts of other gases to the equivalent amount of carbon dioxide with the same global warming potential.
How to calculate carbon dioxide equivalent?
The carbon dioxide equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP: MMTCDE = (million metric tonnes of a gas) * (GWP of the gas). For example, the GWP for methane is 25 and for nitrous oxide 298. This means that emissions of 1 million metric tonnes of methane and nitrous oxide respectively is equivalent …
How to calculate carbon dioxide per therm?
Carbon dioxide emissions per therm are determined by converting million British thermal units (mmbtu) to therms, then multiplying the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to carbon (44/12).
How much carbon dioxide is in a gallon of gasoline?
The amount of carbon dioxide emitted per gallon of motor gasoline burned is 8.89 × 10 -3 metric tons, as calculated in the “Gallons of gasoline consumed” section above. A barrel equals 42 gallons. A typical gasoline tanker truck contains 8,500 gallons.
How much heat does coal produce?
The average carbon coefficient of coal combusted for electricity generation in 2018 was 26.09 kilograms carbon per mmbtu (EPA 2019). The fraction oxidized is 100 percent (IPCC 2006).
How is carbon dioxide reduced in garbage trucks?
Carbon dioxide emissions reduced per garbage truck full of waste were determined by multiplying emissions avoided from recycling instead of landfilling 1 ton of waste by the amount of waste in an average garbage truck. The amount of waste in an average garbage truck was assumed to be 7 tons (EPA 2002).
How much carbon does a deciduous tree store?
A medium growth coniferous or deciduous tree, planted in an urban setting and allowed to grow for 10 years, sequesters 23.2 and 38.0 lbs of carbon, respectively. These estimates are based on the following assumptions:

CO2 Equivalents as A Meaningful Comparison Value
Climate change is an environmental problem that is difficult for many people to grasp. After all, it is not as visible as, for example, the Plastic waste in the environment. In addition, the different climate gases as well as their unequal residence time in the atmosphere are confusing. The value of CO2 equivalents brings all these factors down to a common denominator and creates clarity. …
