Methane CO2 Equivalent Calculator — 公式
## How to Convert Methane to CO2 Equivalent
Methane (CH4) is more potent than CO2 but breaks down faster in the atmosphere.
### Global Warming Potential (GWP)
- **GWP-100**: 28x more potent than CO2 over 100 years
- **GWP-20**: 84x more potent over 20 years
### Formula
**CO2e = Methane (tons) * GWP factor**

计算示例
A facility emits 10 metric tons of methane per year.
- CO2e at GWP-100: 10 * 28 = 280 metric tons CO2e
- CO2e at GWP-20: 10 * 84 = 840 metric tons CO2e
