| Use advice for data set | Users of this data should consider the specific details of the CLT production process in British Columbia, including the materials and energy flows involved from cradle-to-gate. The data focuses on the production stages (upstream activities, transportation, and manufacturing, including packaging) but does not include use or end-of-life stages. Data users must ensure that recycling, energy recovery, and waste treatment processes for CLT are modeled according to local specificities if expanding beyond gate-to-gate. Environmental impacts from capital equipment and human activities are excluded and should be considered if relevant for the expanded system boundary. Always refer to the latest standards and apply up-to-date characterization factors when conducting an LCA with this data. |
| Technical purpose of product or process | Cross-Laminated Timber (CLT) is used as a structural material in building construction for walls, floors, and roofs. It is characterized by its solid wood panel composition, providing a sustainable and strong alternative in modern construction, suitable for residential, commercial, and institutional buildings. |

| General comment on data set | The Athena Sustainable Materials Institute was commissioned by the Forestry Innovation Investment to conduct a cradle-to-gate LCA of BC CLT production. CLT is a category of framing styles characterized by the use of solid wood panels for wall, floor, and roof construction. |

| Time representativeness description | Based on the secondary data sources part of the report, the data quality of Kiln-dried Softwood Lumber can be good within one year. |
| Technological representativeness | |
| Technology description including background system | The whole production process of CLT can be divided into three parts-A1, A2, and A3:“A1 includes the cradle-to-gate production of lumber and resins that are used in CLT manufacture. The upstream resource extraction includes removal of raw materials and processing, processing of secondary material input (e.g., recycling processes) after crossing the system boundary of the previous product system. A1 also includes reforestation processes that include nursery operations (which include fertilizer, irrigation, energy for greenhouses if applicable etc.), site preparation, as well as planting, fertilization, thinning and other management operations.”“For A2-Transportation to factory: Average or specific transportation of raw materials (including secondary materials and fuels) from extraction site or source to manufacturing site (including any recovered materials from source to be recycled in the process);”“In terms of A3, manufacturing of the CLT product, including packaging.” |
