The UNEP OzonAction GWP-ODP Calculator app will help you to convert between values in metric tonnes, ODP tonnes and CO2-equivalent tonnes (or kg) of substances controlled by the Montreal Protocol and their alternatives. The updated application now includes a new “Kigali Amendment” mode.
It is very important to note that in the Kigali Amendment mode the GWP values provided are those specified in the Kigali Amendment to the Montreal Protocol, i.e. GWP values are only assigned to controlled HFCs.
