(xi) Limit and or reduce emissions of hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride

The 1998 Declaration on HCFCs, HFCs and PFCs could also usefully be revisited.

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

Sulphur hexafluoride (SF6)

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).

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).

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

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

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.

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.

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.

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.

Bromotrifluoromethane (Refrigerant gas R 13B1)

Propane 1 Chloro 2,2,2 trifluoroethane (Refrigerant gas R 133a)

There is a chemical that's called perflubron.

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.

Now the good news is, Boranes you can get hold of.

Most toothpastes contain fluoride.

Hydrofluorocarbons (HFCs) Industrial processes

Imports of CFC 11 show a radical decline, even the demand for CFC 12 is partly decreasing while CFC prices tend to increase.

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.

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

Ms Solomon then reviewed an evaluation of the mobile air conditioning sector, which showed the growth of use of HFC 134a and the need to consider end of life management issues for both CFCs and HFCs.

In accordance with the Montreal Amendment to the Montreal Protocol licensing systems should be systematically applied not only to CFCs but also to imports and exports of other ODS, in particular to CTC, TCA, HCFCs, refrigerant blends containing CFCs and methyl bromide.

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.
