## 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.

  1. CO2e at GWP-100: 10 * 28 = 280 metric tons CO2e
  2. CO2e at GWP-20: 10 * 84 = 840 metric tons CO2e
