How to use the greenhouse gas co₂ equivalent calculator
Convert a mass of a greenhouse gas into carbon dioxide equivalent using its global warming potential. Enter mass of gas emitted, global warming potential in the fields above; the carbon dioxide equivalent are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “CO2 equivalent”, “global warming potential”, “methane CO2e”, “calculate greenhouse gas co₂ equivalent”, “find carbon dioxide equivalent”.
Formula
Variables
- m — Mass of gas emitted (kg)
- gwp — Global warming potential
Worked example
With mass of gas emitted = 100 kg, global warming potential = 28, the calculator gives carbon dioxide equivalent ≈ 2,800 kg CO₂e; carbon dioxide equivalent ≈ 2.8 t CO₂e.
Frequently asked questions
What is the greenhouse gas co₂ equivalent calculator used for?
Convert a mass of a greenhouse gas into carbon dioxide equivalent using its global warming potential. It helps with questions such as “CO2 equivalent”, “global warming potential”, “methane CO2e”.
What is the formula for the greenhouse gas co₂ equivalent calculation?
Carbon dioxide equivalent (kg CO₂e) = m × gwp. Carbon dioxide equivalent (t CO₂e) = [Carbon dioxide equivalent] / 1000. Here m is mass of gas emitted (kg), gwp is global warming potential.
What inputs do I need for the greenhouse gas co₂ equivalent calculator?
You need mass of gas emitted in kg, global warming potential. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the greenhouse gas co₂ equivalent calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the greenhouse gas co₂ equivalent result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
