Convert R503 to CO₂e
1 kg=13299kg CO₂e (DESNZ 2026)
CO₂ equivalent
1 kg × 13299 = 13299 kg CO₂e (Total emissions including non-Kyoto products)
Factors for R503
| Reporting basis | kg CO₂e per kg | Row in source file |
|---|---|---|
| Total emissions including non-Kyoto products | 13299 | 850 |
| Emissions including only Kyoto products | 4972 | 848 |
| Emissions including only non-Kyoto products | 8326 | 849 |
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.
