Version 8: Published 22 August 2018
Under the CRC Energy Efficiency Scheme, participants are obliged to collate information about their energy supplies, submit a report about their energy supplies, and buy and surrender allowances equal to the CO2 emissions they generated. The CRC registry will make the conversion from energy to tonnes of carbon dioxide by application of the relevant emission factor. Emissions factors are set out in the table below.
Phase I
2010/11 to 2013/14
| Fuel Type | Measurement Unit | Emissions Factor kgCO2 / per measurement unit |
|---|---|---|
| Electricity | kWh | 0.5410 |
| Natural Gas* | kWh | 0.1836 |
Phase II
2014/15
| Fuel Type | Measurement Unit | Emissions Factor kgCO2 / per measurement unit |
|---|---|---|
|
Electricity (Onsite generated and self‑supplied) |
kWh | 0.490230 |
| Electricity (Grid) | kWh | 0.533100 |
| Natural Gas* | kWh | 0.184557 |
2015/16
| Fuel Type | Measurement Unit | Emissions Factor kgCO2 / per measurement unit |
|---|---|---|
|
