Green finance is a critical enabler in the rapid decarbonisation of the built environment. The sustainable finance revolution demands asset owners deliver high quality, verified outcomes. This presentation will look at how Australian banks are making sustainable finance decisions for property portfolios and why Green Star has become their preferred verification mechanism.
The presentation will draw on WorldGBC data on global trends, before drilling into three linked initiatives designed to unlock capital at a regional and national level. First, Unlocking the value (ASFI & GBCA) set benchmarks for green finance products for new builds, upgrades and operation, including pathways for the residential sector, and positioned certification as the assurance mechanism. Second, GBCA's Financing for Better Buildings and the global guide to sustainable finance, Financing Transformation (USGBC, GBCA, BRE, Singapore GBC) translate green building rating tool outcomes into bankable definitions for finance consistent with 1.5 degree trajectories. Third, WorldGBC and OCBC's paper Unlocking capital maps the alignment of Asia Pacific rating tools, including Green Star, with the ASEAN Sustainable Finance Taxonomy.
Using semi-structured interviews with major Australian lenders, analysis of green-loan eligibility rules, and mapping bank requirements against ASFI benchmarks and Australian and ASEAN taxonomy thresholds, this presentation breaks down the reasons for Green Star preference: (1) ISO-aligned, third-party certification with transparent governance; (2) whole-life performance coverage, embodied and operational carbon, electrification readiness, resilience, circularity and health, supporting both “green” and “transition” products; and (3) clear upgrade pathways via Green Star Performance and climate trajectories that reduce stranded-asset risk.
Using WSBE2026’s “who, what and how” lens, the session identifies actor coalitions driving finance-system change, the decision-useful metrics shaping capital allocation, and the harmonisation steps needed to extend sustainable real-estate finance from market leaders to the mainstream. Recommendations focus on policy, data sharing, and market incentives for rapid scaling.
