Ozone-depleting substances and the greenhouse gases HFCs, PFCs and SF
Appendix 4
GWP contribution from HFCs, PFCs, and SF6, 1993-2020.
The table below shows projections of determined GWP contributions.
The emission projections are determined by starting with a ‘steady state’ consumption using 2005 as the reference year and the cut-off dates for the phasing-out of specific substances, cf. the Statutory Order regulating certain industrial greenhouse gases. A tax effect is also included in the relevant areas of application and expected increases in several applications and sectors are taken into account as much as possible, as are expected reductions in several of the application areas. However, scenarios of the consumption of HFC-404a in the emission calculations are based on conservative developments. The phasing out of HCFC-22 refrigerating plants is expected to lead to greater increases in the consumption of HFC-404a in commercial refrigerating plants than was presupposed, since HFC-404a together with CO2 units are the most obvious substitution possibilities. From 1 January 2000, it is prohibited to build new HCFC-22 systems, and from 1 January 2002, it is prohibited to substitute with new HCFC-22 in existing refrigerators.
The calculated GWP contribution expresses actual emissions, adjusted for imports and exports (the latest basis of calculation).
