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).

2 In light of new knowledge, the determinations of the GWP contributions have been altered in relation to last year’s evaluation /13/.
