A quantity of GHG can be expressed as CO2e by multiplying the amount of the GHG by its GWP . E.g. if 1kg of methane is emitted, this can be expressed as 25kg of CO2e (1kg CH4 * 25 = 25kg CO2e).
How do you calculate emissions?
Calculate the emission rate by multiplying the emission factor by the maximum capacity of the operation (in units of production per hour, material usage per hour, or whatever units the emission factor is in).
What is difference between CO2 and CO2e?
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 that is emitted when fossil fuels (i.e. natural gas, oil, coal, etc.) are burnt.
What is CO2e unit?
The unit “CO2e” represents an amount of a GHG whose atmospheric impact has been standardized to that of one unit mass of carbon dioxide (CO2) , based on the global warming potential (GWP) of the gas.
What does the E mean in CO2e?
Carbon dioxide equivalent or CO 2 e means the number of metric tons of CO2 emissions with the same global warming potential as one metric ton of another greenhouse gas, and is calculated using Equation A-1 in 40 CFR Part 98.
What does the E stand for in CO2e?
Carbon dioxide equivalent or CO 2 e means the number of metric tons of CO2 emissions with the same global warming potential as one metric ton of another greenhouse gas, and is calculated using Equation A-1 in 40 CFR Part 98.
Why is CO2e used?
CO2e, or carbon dioxide equivalent, is a standard unit for measuring carbon footprints . The idea is to express the impact of each different greenhouse gas in terms of the amount of CO2 that would create the same amount of warming. ... Standard ratios are used to convert the various gases into equivalent amounts of CO2.
Is MtCO2e the same as tCO2e?
“Climate change is internationally recognised as a consequence of anthropenic greenhouse gas emissions, which can be measured in Carbon Dioxide Equivalent (CO2e) equivalent CO2 tons (tCO2e) . Its standard unit is MtCO2e or metric tons or tons of carbon dioxide equivalent .
What is a metric ton of CO2?
Measuring 27′ x 27 ′ x 27′ , the CO2 CUBES represent one metric ton of carbon dioxide. The structure reflects the carbon footprint that an average citizen in an industrialized country produces in one month; this same amount is created by a U.S. citizen in only two weeks.
What does gwp100 mean?
The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time , relative to the emissions of 1 ton of carbon dioxide (CO 2 ).
How much CO2 does a tree absorb?
According to the Arbor Day Foundation , in one year a mature tree will absorb more than 48 pounds of carbon dioxide from the atmosphere and release oxygen in exchange.
What is global warming potential measured in?
The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time , relative to the emissions of 1 ton of carbon dioxide (CO 2 ).

Is ozone a greenhouse gas?
Ozone is technically a greenhouse gas , but ozone is helpful or harmful depending on where it is found in the earth’s atmosphere. ... However, at lower elevations of the atmosphere (the troposphere), ozone is harmful to human health.
Is CO2 the same as carbon?
Carbon (often abbreviated with the chemical symbol C) is the sixth most abundant element on Earth. ... Carbon dioxide or CO 2 is the chemical compound of two oxygen atoms and one carbon atom , at room temperature it is gaseous and is a vital gas for life in the atmosphere since it plays a major role in photosynthesis.
How do you calculate gas emissions?
Calculate the emission rate by using this method: Mass Emission rate (lb/hr) = Emission factor (lb/unit) x capacity (unit/hr)
