Global Warming Potential Calculator — 公式
## 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.

计算示例
A farm releases 100 kg of methane (GWP = 28) over a year.
- CO2-equivalent = 100 kg x 28 = 2,800 kg CO2e
- In tonnes: 2,800 / 1,000 = 2.8 tonnes CO2e
