How is CO2 equivalent calculated?

How is CO2 equivalent calculated?

Carbon dioxide (CO2) equivalent is a measure of how much a gas contributes to global warming, relative to carbon dioxide. 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).

How do you convert CO2 to CO2 equivalent?

Carbon dioxide equivalent (CO2e) 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 CO2 emissions from fuel consumption?

An average consumption of 5 liters/100 km then corresponds to g/l / 100 (per km) = 132 g CO2/km. Petrol: 1 liter of petrol weighs 750 grammes. Petrol consists for 87% of carbon, or 652 grammes of carbon per liter of petrol.

How do you calculate CO2 from KWH?

For electricity, the calculation will be 15,000kWh x 0.21233kgCO2e ÷ 1,000 = 3.2tCO2e. For natural gas, the calculation will be 20,000kWh x 0.18316kgCO2e ÷ 1,000 = 3.7tCO2e.

What is meant by CO2 equivalent?

Carbon dioxide equivalent or CO2e 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.

How is CO2 emission factor calculated?

Thus, the emission factor is the sum of emissions of CO2eq of the human activity described as mass unit of CO2eq / reference flows. For example: the EF for the natural gas is the sum of the combustion (0.205 kg CO2eq / kWh ICV) and the upstream (i.e. the production and transport of the gas) (0.0389 kg CO2eq / kWh ICV).

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).

How do you calculate carbon factor?

An emissions factor tells you how much CO2e is created per unit of activity. For example, taking the train emits 0.05945kg of CO2e per mile. Multiplying that by how many miles you travelled will give you the carbon footprint of that journey.

How much CO2 is in the atmosphere?

Based on preliminary analysis, the global average atmospheric carbon dioxide in 2020 was 412.5 parts per million (ppm for short), setting a new record high amount despite the economic slowdown due to the COVID-19 pandemic.

What is a tonne of CO2 equivalent to?

As an example, one tonne of carbon dioxide equivalent amounts to: Around one month's emissions from an average person in the U.K (where per capita emissions are 12.1tCO2e per year [9]. In comparison, one tonne amounts to more than a year of emissions for an average person living in Sri Lanka!
