Project Overview

101 Collins Street is one of Melbourne’s most iconic premium-grade commercial office towers. As climate risks intensify and regulatory expectations evolve, the building engaged Rewild to undertake a comprehensive Climate Scenario Analysis aligned with the Australian Sustainability Reporting Standard (ASRS) AASB S2 requirements. The purpose of the assessment was to provide a clear, forward‑looking understanding of how climate-related physical risks, transition dynamics, and climate-related opportunities may affect the building’s operations, asset value, resilience and financial planning across short, medium and long-term horizons.

The analysis applied both a Paris-aligned (1.5°C) scenario and a Business-as-Usual (2.5°C+) scenario, enabling 101 Collins Street to understand its exposure under best‑case and worst‑case climate futures.
