The sources are very disparate and typically small with long lag times between gas utilisation and eventual emission – particularly for HFC refrigerants and for Sulfr hexafluoride. Although sf6 gas 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 insulating gas emissions are being managed and reported under existing

Emissions of the powerful greenhouse gas sf 6 are rising

Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago. Plus, improvements in the energy intensity of the global economy (the amount of energy used per unit of economic activity) are slowing.
