Hydrofluorocarbons (HFCs)

Perfluorocarbons (PFCs)

Many Parties mentioned in this regard the substitution of chlorofluorocarbons (CFCs) by HFCs.

Most Parties reported emissions of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6), although not uniformly.

From 1990 to 1995 the relative shares of the gases did not change significantly, with the exception of HFCs, PFCs and SF6.

Industrial processes Most of the Parties reported emissions of the new gases, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

Eighteen Parties (15 per cent) provided estimates of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and or sulphur hexafluoride (SF6).

The emissions of other GHGs (HFCs, PFCs, SF6) are expected to grow significantly, especially after 2000.

Hydrofluorocarbons (HFCs) Industrial processes

3 The anthropogenically produced greenhouse gases include carbon dioxide (CO2) methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

CH4 and N2O accounted for 11 per cent and 4 per cent of total emissions, while emissions of HFCs, PFCs and SF6 taken together were 1.8 per cent of total emissions.

At a minimum, information should be provided on the following greenhouse gases carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and sulphur hexafluoride (SF6).

Fluorocarbons and other greenhouse gases

Figures were also given for the indirect GHG carbon monoxide (CO), nitrogen oxides (NOx) and non methane volatile organic compounds (NMVOC), but not for hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulphurhexafluoride (SF6), emissions of which the team assume were small or zero in 1990.

Parties that made HFC projections for 2000 expect a considerable growth, while PFC projections show a decreasing trend.

HFC, PFC and SF6 should be added no later than 2000 to the basket of gases for the above reduction objectives.

(b) Use of selected low GWP fluorocarbons instead of high GWP fluorocarbons

The relative importance of the other greenhouse gases (HFCs, PFCs and SF6) increased over the period 1990 to 1995, from 1.3 to 1.8 per cent of total GHG emissions.

(b) Use, as far as possible, of selected low GWP fluorocarbons instead of high GWP fluorocarbons and

For the majority of Parties emissions of PFCs have decreased since 1990, while emissions of HFCs and SF6 have increased, HFCs in particular, owing to their use as a replacement for ozone depleting substances controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer.

Emissions of HFCs have increased significantly since 1990, with many Parties remarking on the increasing use of HFCs as replacements for ozone depleting substances.

(a) Product standards with respect to leakages of fluorocarbon emissions

(a) Avoid, as far as possible, the use of fluorocarbons in testing procedures

Companies switching from CFCs to other substances were accumulating growing volumes of CFCs for disposal, but could not keep them in storage indefinitely, and lacked the technical and financial capacity to destroy them.

(c) Reporting on the production, consumption and national emissions of fluorocarbons

Halocarbons The main concern with the family of man made halocarbons has been their impact on the destruction of the stratospheric ozone layer.

CF4 carbon tetrafluoride

PFC perfluorocarbon SF6 sulphur hexafluoride

In line with the revised guidelines, the majority of Parties have extended their inventories to include hydrofluorocarbons, perfluorocarbons, and sulphur hexafluoride and mention them in the policies and measures text in second national communications.

(Agenda item 9 (a))

352. Annex VI prohibits deliberate emissions of ozone depleting substances, which include halons and chlorofluorocarbons (CFCs), and sets limits on the emissions of sulphur oxide and nitrogen oxide from ship exhausts.

segmental performance data based around energy use, materials use, emissions (CO2, NOx, SO2, CFCs, etc.) and waste disposal routes

The main problem occurs with HCFCs and blends of CFCs which gradually take over portions of the CFC market and might then be the object of illicit commerce themselves.

Hydrofluorocarbon (HFC) emissions could, however, represent 3 4 per cent or more of total GHG emissions in 2000, depending on the speed at which the use of chlorofluorocarbons (CFCs) is phased out in the fishing fleet.
