Synthetic greenhouse gases

Increase to licence application fees and penalty units:
On 28 December 2012, amendments to the Ozone Protection and Synthetic Greenhouse Gas Management Regulations came into effect. These amendments include:

Equivalent carbon price for synthetic greenhouse gases
From 1 July 2012, an equivalent carbon price was applied to certain synthetic greenhouse gases - hydrofluorocarbons, perfluorocarbons (excluding gases produced from aluminium smelting) and sulfur hexafluoride (including equipment or products which contain these gases).

There are provisions for exemptions from the equivalent carbon price, some exemptions are currently in place and others are coming into effect soon.

Kyoto Protocol

The Australian Government is committed to reducing our emissions of the synthetic greenhouse gases (SGGs) listed under the Kyoto Protocol:

SGGs often replace ozone depleting substances (ODSs), however, while these gases do not deplete the ozone layer, most have very high global warming potentials (GWPs). The most common SGG used in Australia is HFC-134a, which has a GWP of 1300, meaning that it is 1300 times as potent as carbon dioxide. Other SGGs are even more powerful global warmers, with PFCs having GWPs between 6500-9200 and SF6 having a GWP of 23 900.

Sources of SGG emissions

SGG emissions occur mainly as a consequence of leakage or release from various industrial, commercial and domestic refrigeration and airconditioning equipment, or as a by-product of industrial activity. The main sources of SGG emissions include:

Australia's National Greenhouse Gas Inventory estimated that 4.2 Mt CO2e of HFCs were emitted in 2005, while emissions of PFCs and SF6 were 1.6 Mt CO2e and 0.5 Mt CO2e, respectively. In total, the release of SGGs accounts for one to two per cent of Australia's emissions.

The Australian Government's Industrial Process Sector Greenhouse Gas Emissions Projections 2007 suggests that, under business-as-usual circumstances, HFC net emissions will grow to 6.7 Mt CO2e per annum over the Kyoto Period.

Assessment of alternative technologies and practices

The Intergovernmental Panel on Climate Change (IPCC) and the Montreal Protocol's Technology and Economic Assessment Panel (TEAP) released a comprehensive special report on Safeguarding the Ozone Layer and the Global Climate System: Issues Related to Hydrofluorocarbons and Perfluorocarbons in 2005. The report assesses alternative technologies and practices for reducing the net warming impacts of SGGs where they are used as replacements for ODSs and notes that, for all sectors, reductions in direct emissions are available and can be achieved through:

Australia's efforts to reduce SGG emissions

In December 2003, the Australian Government amended the Ozone Protection Act 1989 - now the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 - extending its scope to incorporate SGGs.

As part of the bilateral climate change partnerships program, Australia is working with both the United States and New Zealand to support SGG abatement projects. Under the Australia-United States Climate Change Partnership, projects are being undertaken to:
