Convert R401A to CO₂e
1 kg=1130kg CO₂e (DESNZ 2026)
CO₂ equivalent
1 kg × 1130 = 1130 kg CO₂e (Total emissions including non-Kyoto products)
Factors for R401A
| Reporting basis | kg CO₂e per kg | Row in source file |
|---|---|---|
| Total emissions including non-Kyoto products | 1130 | 631 |
| Emissions including only non-Kyoto products | 1112 | 630 |
| Emissions including only Kyoto products | 18 | 629 |
The factor is applied to the mass of refrigerant released to the atmosphere, for example the amount added during servicing to replace a leak. GWP basis: AR5; AR6 where no AR5 value exists (DESNZ 2026 methodology, Table 1 note 5).
DESNZ gives separate columns for gases covered by the Kyoto Protocol and for all gases including non-Kyoto ones (for example ozone-depleting substances controlled under the Montreal Protocol). Use the column that matches the scope of your reporting and state it.
