GWP Calculator
Estimate carbon dioxide equivalent emissions using greenhouse gas quantity and global warming potential factors for reporting, planning, and environmental analysis.
CO2e Calculator
Enter the gas amount and its GWP factor. CO2e equals amount multiplied by GWP.
Result updates automatically.
Formula: CO2e = greenhouse gas amount × GWP factor.
How to Calculate Global Warming Potential
Global warming potential compares how much heat a greenhouse gas traps relative to carbon dioxide over a selected time horizon. CO2e converts different gases into a common reporting unit.
Reference gas with GWP 1.
Methane has a higher warming impact per unit mass than CO2.
Nitrous oxide is often used in agricultural and industrial emissions analysis.
Use published factors from your reporting standard when required.
GWP Formula Notes
For regulated greenhouse gas inventories, use the exact GWP factors and time horizon required by your reporting framework.
GWP Calculator FAQ
What does GWP mean?
GWP means global warming potential. It compares a greenhouse gas to carbon dioxide over a defined time horizon.
What is CO2e?
CO2e means carbon dioxide equivalent, a common unit for comparing emissions from different gases.
Can I use custom GWP factors?
Yes. Select custom and enter the factor required by your reporting source or standard.
