--- This paper assesses the feasibility of using atmospheric
measurement of fluorinated greenhouse gases (HFCs, PFCs and
SF6) for the review and verification of greenhouse gas inventories
provided by national governments. For this purpose, available
data were compiled. It was found that atmospheric measurements
of these gases are available and provide an indication of global
annual emissions with sufficient certainty to reach the following
conclusions: Within the uncertainty of the method, it was found
that emissions of HFC-23, a by-product of HCFC-22 production,
as obtained from atmospheric measurements did not decrease
as fast, as the countries have reported. In contrast, SF6
concentrations in the atmosphere suggest higher emissions than
reported by countries. Regional emission estimates from atmospheric
measurements are still in a more pioneering state and cannot
be compared to national estimates. Intensified efforts to measure
HFCs, PFCs and SF6 in the atmosphere are recommended. | | Keywords: atmospheric measurements; fluorinated greenhouse gases (HFCs, PFCs, SF6); hydrofluorocarbons (HFCs); Kyoto Protocol; perfluorocarbons (PFCs); sulphur hexafluoride (SF6); United Nations Framework Convention on Climate Change (UNFCCC) |
