  • Members of the European Union do not report their individual consumption; that is reported in aggregated form for all the member states under “European Union”.
  • European Union consumption for ODS includes the United Kingdom, including for the years after which the United Kingdom left the European Union.
  • European Union consumption for HFC excludes the United Kingdom, even for the years when the United Kingdom was part of the European Union.
  • The GWP values for substances controlled under the Montreal Protocol are as reported in the 2022 Scientific Assessment of Ozone Depletion.
  • Negative values for consumption for a given year imply that quantities destroyed or quantities exported for the year exceeded the sum of production and imports, implying that exported quantities came from stockpiles, or the destroyed quantities came from stockpiles or recovered/recycled substances.
  • Negative values for production for a given year imply that quantities destroyed or quantities exported for feedstock uses exceeded production for that year, implying that the destroyed or exported quantities were taken from stockpiles.
  • For reductions, negative values may occur, or reduction trends may not be evident, even though a party may have maintained compliance or had a reducing trend in ODP tonnes, when there are multiple substances in an annex group due to differences in the proportionality of the (a) amounts in metric tons for different substances between the baseline years and the reduction years; (b) multiplication factors, ODP and GWP values, for different substances.
  • Reductions are derived only for years in which control measures are in effect for the annex group and obligations are in force for the party.
  • Production = actual production – feedstock and process agent uses – destroyed amounts – QPS uses for methyl bromide.
  • Consumption = production + imports – exports – feedstock and process agent uses – destroyed amounts – QPS uses for methyl bromide + exports to non-parties for ODS only.
