National emission factors database

18 Nov 2024

The national emission factors database is a new standard for building product emission factors in Australia.

The database is integrated into the NABERS Embodied Carbon rating tool and can be used independently when measuring embodied carbon. It will serve as a reliable resource for emission factors where product-specific Environmental Product Declarations (EPDs) are unavailable.

Developed with industry collaboration

Development of the database occurred through stages of data collection, analysis, and, most importantly, industry consultation with a diverse range of stakeholders. Stakeholders ranged from product manufacturers, manufacturing industry bodies and LCA experts, to the building industry more broadly.

As part of our ongoing commitment to transparency, we are making available the technical documentation behind the database so that industry has access to the calculations performed at a material sub-category level. You can find more details about the methodology within the technical workbook.

You can also download the list of EPDs that were used to develop the emission factors.
