Ozone depleting substances and the greenhouse gases HFCs, PFCs and SF6
Appendix 4 -GWP contribution from HFCs, PFCs,
and SF6 1993-2020.
The table below shows determined GWP contributions.
The emission projections are determined by starting with a steady state
consumption using 2001 as the reference year and employing a series of dates for the
phasing-out of specific substances in accordance with the phasing-out process of strong
greenhouse gases. A charge effect is also included in the relevant areas of application
and expected increases in several application areas are taken into account as much as
possible, as are reductions in several of the applications areas.
The calculated GWP contribution expresses the actual emission, corrected for import and
export (the latest basis of determination).
