SOH Event Carbon Counter Template - Sydney Opera House

Sydney Opera HouseEvent Carbon Counter TemplateGas Emissions Calculations (and other Fuels combusted on site)OverviewGas emissions are calculated by measuring the gas consumed through the various gas metersThis should be adjusted to reflect the incremntal gas use for the event, not the baseload gas use for SOHGas used can be directly converted into equivalent emissions using the appropriate emissions factor for the stateGas usage information is entered into the blue cells belowDiesel fuel was used for the flame show in 2011.Kilolitres (kL) of diesel can be converted into gigajoules (GJ) using the energy content factor 38.6 GJ/kL1.
