Key Insights

The greatest opportunity is not creating new diversion streams, but increasing participation in existing ones. The 2025 waste audit revealed that most materials entering landfill bins could already be recycled, composted, or diverted through programs available on campus.

Expanding Reuse and Circularity

More than 7 tonnes of materials were kept in circulation through initiatives such as the Free Store and Furniture Rehome Program.

¹û½´ÊÓÆµ Eats provided over 8,800 meals to students and community members while advancing food recovery, reuse, and food security initiatives across campus.

  • Energy intensity (measures energy consumption per unit area (ekWh/m² or GJ/m²): 340.51 ekWh/m2

Scope 1 (direct)  and 2 (indirect) emissions increased by approximately 18% in 2024/25

Despite the increase in emissions, campus energy intensity decreased, indicating improved energy efficiency per square metre.
