Numerous studies have investigated the environmental benefits of cross laminated timber (CLT) construction in comparison to conventional construction, typically using a life cycle assessment (LCA). Yet, there is a need for further in-depth analysis of the environmental performance of CLT construction using a more comprehensive approach, in order to provide a more realistic estimation of the potential for CLT construction to reduce greenhouse gas (GHG) emissions associated with buildings. This research aims to fill this knowledge gap by conducting a streamlined life cycle assessment to quantify embodied GHG emissions, using hybrid coefficients from the EPiC Database, for a real case study; a five storey multi- residential CLT building about to be constructed in Melbourne, Australia. The new knowledge will provide some of the critical knowledge that is currently lacking in relation to the life cycle GHG emissions performance of CLT construction and the potential for this form of construction to reduce GHG emissions associated with the construction industry.
