Hardwood timber production {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes:process begins with the management of hardwood forests and ends with the supply of hardwood products. It includes fire control harvesting and regeneration of the forests coup. Remark: This is an unallocated coproducing process which produces high-quality sawlogs, low quality sawlogs, veneer logs, pulp logs.The data is averaged across three regions. Geography: Refers to an average production in the Australia. Technology: Average Time period: Data collected for 2006 Version: 1.0 Record: Data entry by: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU Generator: Generator/publicator: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU

Elementary flow outputs
| Flow | Compartment | Sub-compartment | Amount | Unit | Comment |
|---|---|---|---|---|---|
| Carbon dioxide, fossil | Emission to air | low population density | 0.0 | kg | 16.8 kg per M3 timber is reported however this is assumed to be from upstream processes which are accounted seperately in this inventory. |
| Carbon dioxide, non-fossil | Emission to air | low population density | 334.0637 | kg | Carbon evolved based on reported quantities of residue burnt and fuel reduction burns. |
| Carbon monoxide, non-fossil | Emission to air | low population density | 19.5 | kg | (2,2,2,1,1,na) This is reported as carbon monoxide and a small amount of this could be from upstream processses howeverthis would be insignificant compared to the emissions from combustion of biomass on site so therefore the carbon monoxide has been labelled as biogenic. |
| Dinitrogen monoxide | Emission to air | low population density | 0.05 | kg | (2,2,2,1,1,na)This value could include a small amount from upstream processses however this would be insignificant compared to the emissions from combustion of biomass on site. |
| Methane, non-fossil | Emission to air | low population density | 0.86 | kg | (2,2,2,1,1,na)This is reported as methane and a small amount of this could be from upstream processses howeverthis would be insignificant compared to the emissions from combustion of biomass on site so therefore the methane has been labelled as biogenic. |
| Nitrogen oxides | Emission to air | low population density | 0.55 | kg | (2,2,2,1,1,na)This value could include a small amount from upstream processses however this would be insignificant compared to the emissions from combustion of biomass on site. |
