The Kigali Amendment to the Montreal Protocol entered into force on 1st January 2019. It addresses the shift from higher Ozone Depleting Potential (ODP) freons (mainly HCFCs and CFCs as far as our refrigerant gases are concerned) to lower / zero ODP freons (HFCs) that was mandated under the Montreal Convention, but that inadvertently simultaneously lead to the use of freons with a higher Global Warming Potential (GWP).
SPO committed to switch to refrigerants with zero ODP and lower GWP freons in accordance with the Kigali Amendment. We have a target of a 50% reduction of HCFC-R22 refrigerant freons used in the fleet by 2021 and eventually from the remaining vessels. In 2020, our use of HCFC-R22 reduced by 19.2%.
Usage of various ODS remains stable y-o-y, with consistent use of HFC-R417a and HFC-R407c. However, both have ODPs of zero.
