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

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

Poly Tetra Fluoro Ethene

Mr. Kuijpers noted that related gases (CFCs, HFCs, HCFCs and PFCs) were used in a variety of sectors, including refrigeration and air conditioning, foams, medical aerosols, fire protection and non medical aerosols.

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

The communication did not include emission figures for hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6 ) and only aggregated emission levels for precursor gases were provided.

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

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

and 52 1,1,1 trifluoroethane, see 2.2 3340

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.

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

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

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).

(a) Reducing international trafficking of existing chlorofluorocarbons and ensuring a timely phase out of methyl bromide and hydrofluorocarbons

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

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.
