NABERS SPI 2025 launches milestone

08 May, 2025
NABERS SPI 2025 launches milestone



The NABERS Sustainable Portfolios Index (SPI) 2025 has officially launched, showcasing the achievements of 67 property portfolios from 30 leading companies and reaffirming the commercial property sector’s growing commitment to sustainability, efficiency, and environmental performance.

Now in its seventh year, the SPI ranks office, shopping centre, and — for the first time — hotel portfolios based on NABERS ratings for energy, water, waste, and indoor environment quality.

This year’s results highlight a continued upward trajectory in performance, with the inclusion of hotels marking a major milestone for the index.

CapitaLand and Schwartz Family Company are the first hotel operators to participate, representing approximately 6,000 rooms across Australia.

Key highlights from the 2025 SPI include:

  • 67 portfolios: Comprising 48 office, 16 shopping centre, and three hotel portfolios, representing over 500 assets.
  • Top performers: Quality Green Group and Walker Corporation lead the Office Energy Index, while QIC Real Estate tops the Shopping Centre Energy Index.
  • New data features: The SPI introduces the Renewable Energy Indicator (REI) and Electrification Percentage, providing greater transparency into renewable energy adoption and electrification progress.

Since its inception in 1999, NABERS has helped buildings collectively save nearly $2 billion in energy bills and reduce 13.4 million tonnes of carbon emissions, further solidifying its role in supporting the sector’s climate and efficiency targets.

Magali Wardle, Head of Market Development at NABERS, said: “The NABERS SPI 2025 shows how leaders in Australia’s property sector are transforming targets into tangible results.

“Whether they’re fine-tuning decades-old office buildings or benchmarking entire hotel portfolios, the leaders are showing how measuring performance translates into more efficient, attractive and more commercially valuable assets.”

Participation in key categories continues to grow, with 13 shopping centre portfolios now disclosing 100 per cent energy coverage, up from seven last year.

The new REI allows for more accurate tracking of renewable energy usage, with QIC Real Estate Active Retail Property Fund achieving an impressive 97.46 per cent renewable energy usage — leading both the Shopping Centre category and the overall index.

The SPI 2025 also introduces user-friendly tools and new data points like Electrification Percentage, helping portfolio owners and managers make informed decisions on their sustainability journey and progress towards net-zero goals.

Wardle added: “The SPI isn’t just about who ranks highest. It gives asset owners a clear picture of where they stand, and where we can go together.

“Every portfolio that discloses performance is contributing to Australia’s climate goals and helping to deliver more efficient buildings.”

With expanding participation and new metrics, the NABERS SPI 2025 sets a new benchmark for environmental accountability and progress across Australia’s property sector.
