Emission factor summary

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.8. The product 'cross-laminated timber' is an engineered wood product. Regular timber is an anisotropic material, meaning that the physical properties change depending on the direction at which the force is applied. By gluing layers of wood at perpendicular angles, the panel is able to achieve better structural rigidity in both directions. It is similar to plywood but with distinctively thicker laminations. Cross-laminated timber (CLT) is distinct to glued laminated timber, a product with all laminations orientated in the same way. CLT is a wood panel product made from gluing layers of solid-sawn timber together. Each layer of boards is oriented perpendicular to adjacent layers and glued on the wide faces of each board, usually in a symmetric way so that the outer layers have the same orientation. An odd number of layers is most common, but there are configurations with even numbers as well (which are then arranged to give a symmetric configuration). CLT is used as a construction material, e. g. for walls, floors, and roofs. The cut-off classification is allocatable product. The activity type is market activity. The reference product amount is 1.
