“…CO2 emissions = energy content of fuel X CO2 emission factor X combustion factor X 1000 (4) where CO2 emissions are in tons of CO2 (t CO2), energy content of fuel is in gigajoules, CO2 emission factor is in kilotons COT/GJ (508 X 10-'' for New South Wales (NSW) natural gas), and combustion factor is 0.995, CH4 emissions = energy content of fuel X CH4 emission factor X 1000 X 21 (5) where CH4 emissions are in tons of CO2 equivalent, energy content of fuel is in gigajoules, and CH4 emission factor is in kilotons CH4/GJ (8X 10"^ for turbine and 1 X 10"'" for boiler).…”
