SPR worked with FirstMac, Australia's largest non-bank lender, to quantify financed (Scope 3) emissions across its residential mortgage portfolio. Our work provided a defensible, point-in-time baseline aligned with the Greenhouse Gas Protocol, PCAF guidance and forthcoming AASB S2 climate-disclosure requirements. The project developed a portfolio calculator that estimates dwelling energy use by postcode, dwelling type and build year, converts energy to emissions using jurisdictional NGA factors, and attributes emissions to FirstMac based on loan-level allocation factors. The analysis presented results segmented by state and dwelling type to show where emissions are concentrated across the portfolio.
The project also delivered a practical data-improvement roadmap, outlining how additional property and appliance information, solar PV and gas-connection data, and periodic updates to underpinning datasets can progressively lift accuracy.
