Abstract
This study assesses the potential contribution to global warming due to emissions from hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6) until 2100. The emission scenarios start with emissions inferred from atmospheric observations. To project future emissions a top-down approach is chosen. Economic projections are combined with different assumptions about the diffusion of improved technology. The greenhouse impact of emissions of HFCs, PFCs and SF6 in different scenarios is evaluated and compared to the historical contribution from anthropogenic halocarbons. Distinctly different results for the historical emission level are derived depending on which compounds are included and which net values for the global warming potential of halocarbons are used. This implies that the historical radiative effect of greenhouse gas emissions associated with global halocarbon usage can currently not be scientifically defined.
