About ICM Database

The Integrated Carbon Metrics (ICM) Database is an Australian-specific life cycle inventory providing carbon footprint intensities for construction and building materials. It includes results from both a process method (based on AusLCI process data) and a hybrid method (combining process data with input-output data to capture upstream activities).

Methodology description	Emission factors are calculated using a Hybrid Life Cycle Assessment (LCA) methodology. Hybrid LCA combines the process-level specificity of traditional LCA with the economy-wide comprehensiveness of Input-Output Analysis (IOA). Several approaches to this combination exist; in all cases, specific data on individual processes are connected with data from an input-output model (Wiedmann, 2010). The approach used for this database is integrated hybrid LCA, in which a monetary input-output table is connected to a physical process matrix (Suh, 2004; Wiedmann, 2010). The different types of hybrid LCA are described in detail in Crawford et al. (2018). Two main data sources are hybridised: process data from the Australian National Life Cycle Inventory Database, and input-output data from an Australian national Supply-and-Use Table (SUT). The integration of these datasets and the underlying calculations are described in detail in Yu and Wiedmann (2018) and Yu et al. (2020). References Crawford, R.
