Convert HFC-134 (CHF2CHF2) to CO₂e
1 kg=1260kg CO₂e (AR6, 100-year)
1 kg × 1260 = 1260 kg CO₂e (GWP-100, IPCC AR6)
Global warming potential of HFC-134
| Assessment report | GWP, 100-year | Source page |
|---|---|---|
| IPCC AR6 | 1260 | 2 |
| IPCC AR5 | 1120 | 2 |
| IPCC AR4 | 1100 | 2 |
To convert a mass of HFC-134 to CO₂ equivalent, multiply it by its global warming potential (GWP). For example, 10 kg × 1260 = 12,600 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.
The UK government conversion factors (DESNZ 2026) give 1120 kg CO₂e per kg for this gas (basis: AR5; AR6 where no AR5 value exists (DESNZ 2026 methodology, Table 1 note 5)).
Group: Hydrofluorocarbons (includes unsaturated hydrofluorocarbons).
