Convert Methane – non-fossil (CH4) to CO₂e
1 kg=27kg CO₂e (AR6, 100-year)
CO₂ equivalent
1 kg × 27 = 27 kg CO₂e (GWP-100, IPCC AR6)
Global warming potential of Methane – non-fossil
| Assessment report | GWP, 100-year | Source page |
|---|---|---|
| IPCC AR6 | 27 | 2 |
| IPCC AR5 | 28 | 2 |
| IPCC AR4 | 25 | 2 |
To convert a mass of Methane – non-fossil to CO₂ equivalent, multiply it by its global warming potential (GWP). For example, 10 kg × 27 = 270 kg CO₂e using the AR6 value.
The GHG Protocol's table states that "the use of the latest values (AR6) is recommended", and notes that AR4 and AR5 values are sometimes used for inventory and reporting purposes. Use the set your reporting framework asks for and keep it the same across years.
