Methodology
Natural gas is composed mostly of methane. A little of this methane escapes to the atmosphere and adds to the greenhouse problem as the gas is pumped from the gas well (in Moomba, SA) to the users. However, most of the greenhouse emissions come from the end use of the gas when it is combusted for hot water or for other sources of heat.
Natural gas consumption for the Newcastle LGA has been scaled from State average data. Additional gas statistics are provided by AGL Energy Networks and the Australian Gas Association.
For 1999/00, 807 new customers were connected to natural gas. Total gas usage increased by 30,160 GJ in this year compared to the previous 12 month period. This increase is influenced by climate variations as well as the increase in customer numbers.
Coefficients
The amount of CO2-e from production and transport of the gas and the amount of actual CO2 released into the atmosphere from combustion of the gas have been calculated using a general coefficient of 0.0675 tonnes of CO2 per gigajoule (Gj) of gas. This expresses the amount of total CO2 that enters the atmosphere from the use of gas from the well to the flame.
