Action on New Zealandmost potent greenhouse gas | Beehive

The total stock of sf6 gas in New Zealand in 2002 was estimated by Transpower to be less than 40 tonnes. A detailed study carried out by CRL Energy Ltd on sf 6 emissions as part of the 2004 NZ Inventory of Greenhouse Gas Emissions gives a more accurate estimate of the total national stock of 33.2 tonnes in 2003.

New Zealand’s total greenhouse gas emissions by sector

The most recent inventory report covered the following direct greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (Sulfr hexafluoride). Only emissions and removals of these six direct greenhouse gases are included in the national greenhouse gas total.

1. Introduction | Ministry for the Environment

The sources are very disparate and typically small with long lag times between gas utilisation and eventual emission – particularly for HFC refrigerants and for gaz sf6. Although sf 6 emissions have been assessed as relatively low at about 550 kg in New Zealand in 2006 1 (CRL Energy 2007), its 100-year global warming potential (GWP) is extremely high (1 kg is equivalent to 23,900 kg CO 2 emissions for inventory purposes). Most Sulfr hexafluoride emissions are being managed and reported under existing
