Notes
- Energy emissions factors from GHG inventory
- All energy contents NZRC average 1998-2007 except:
- -Premium petrol (2006/2007)
- -Diesel (50ppm diesel average only)
- -Aviation gasoline (Table L2 MED Energy Data File)
- All petrol 95 octane and above is assumed to have the same emissions factor
- All diesel is assumed to have the same emissions factor (as long as only one
- Grade produced and sold in New Zealand)
- GWP: Global warming potential
- Medium fuel oil qualities are assumed at the average of light and heavy fuel oil
- Power station fuel oil is assumed to be the same as heavy fuel oil (180 cst)
- Qualities will be reviewed annually but change will only be made if there is an
- ongoing significant trend (greater than 0.5% movement) showing a change from the data used to calculate these factors.
