CO2-Equivalent vs Mass of Gas Emitted
Fórmula
## Understanding Global Warming Potential Global Warming Potential (GWP) compares the heat-trapping ability of a greenhouse gas to CO2 over a specified period, typically 100 years. ### Formula **CO2-Equivalent (kg) = Mass of Gas (kg) x GWP Factor** Common GWP-100 values: Methane (CH4) = 28, Nitrous Oxide (N2O) = 265, SF6 = 23,500. A higher GWP means the gas traps more heat per kilogram than CO2.
Ejemplo Resuelto
A farm releases 100 kg of methane (GWP = 28) over a year.
- 01CO2-equivalent = 100 kg x 28 = 2,800 kg CO2e
- 02In tonnes: 2,800 / 1,000 = 2.8 tonnes CO2e
Preguntas Frecuentes
What does GWP-100 mean?
GWP-100 measures the total warming effect of a gas over 100 years relative to CO2. It is the most commonly used time horizon in climate policy.
Why is methane GWP so much higher than CO2?
Methane absorbs infrared radiation about 80 times more effectively than CO2 over 20 years, but it breaks down faster, so the 100-year GWP is 28.
Where do GWP values come from?
The Intergovernmental Panel on Climate Change (IPCC) publishes GWP values in its assessment reports. The latest values come from the AR6 report.
