The values will need to be applied to the submissions we receive for evaluation from Australian, state or territory governments. The Guidance Note outlines the emissions values for use in submissions to Infrastructure Australia, including parameter values for sensitivity testing, and how they should be applied. 

The Modelling Report provides detailed information on the method used to estimate the emissions values and the data sources used. 

The emissions values, which are based on modelling of the least-cost approach to achieve Australia’s legislated emissions reductions targets, are a tool to be used to measure the social impacts of carbon emissions in infrastructure proposals.  

The values were developed in consultation with key stakeholders across the Australian, state and territory governments, Treasury, CSIRO, and Australian National University, and were endorsed by the nation’s Infrastructure and Transport Ministers in December 2023.
