Journal article: Replacement scenarios for construction materials based on economy-wide hybrid LCA
By comparing residential and non-residential building stock scenarios using an IO-based hybrid LCA scenario method, this study gains insight into potential emissions reductions opportunities. The best-case emissions scenario would require all new building stock (both residential and non-residential) to be constructed from a timber structural design (timber scenario), with the worst-case emissions scenario being when new building stock is constructed from conventional reinforced concrete design (BAU scenario). If 100% of new residential building structures were to be constructed from EWPs instead of 100% reinforced concrete, a saving of 26 Mt CO2e can be achieved by 2050.
