About this report
This report has been prepared by the Commonwealth Scientific and Industrial Research Organisation for the Department as a means to provide information on global and domestic emissions of synthetic greenhouse gases (SGGs) controlled by the United Nations Framework Convention on Climate Change (UNFCCC) and now by the Montreal Protocol on Substances that Deplete the Ozone Layer (in relation to hydrofluorocarbons or HFCs).
The report summarises atmospheric measurements of synthetic greenhouse gases arriving at the Cape Grim facility in Tasmania for the period 1980 to 2017 from the southern hemisphere and from Melbourne. It uses those measurements and established modelling systems to estimate emissions of the measured synthetic greenhouse gases both globally and from Australia.
These measurements and emission estimations are an important resource for the global scientific community to draw upon when measuring progress by the UNFCC in controlling and reducing emissions of ozone depleting substances.
The report finds that all the atmospheric concentrations of the synthetic greenhouse gases have increased year on year and that both global and domestic emissions of synthetic greenhouse gases have increased. Total Australian emissions estimated of the synthetic greenhouse gases are however lower than those estimated for the National Greenhouse Gas Inventory. Emissions of sulfuryl fluoride have increased, but are still small overall.
