FY2025 is a year marked by innovation, impact and measurable progress towards a more sustainable built environment.
In 2025, NABERS expanded its influence and amplified its impact. New tools, partnerships and policies drove strong growth in ratings, while operational improvements reinforced confidence in the system’s credibility, consistency and useability. Industry leadership in electrification, embodied carbon and net zero commitments drove progress, with NABERS providing the backbone for transformation.
FY25 highlights: A year of impact:
- Record growth in certifications: 120% increase in certified ratings compared to FY24, led by public school portfolio assessments across multiple jurisdictions (3,500 ratings) and a 40% rise in Hotel ratings.
- Launch of NABERS Embodied Carbon tool: A new benchmark enabling measurement of upfront embodied carbon, supported by rules, a national database, a calculator and trained Assessors.
- Sustainable Portfolios Index expansion: 67 portfolios across 30 companies and 500-plus assets, with 20 hotels joining for the first time and new indicators for renewable energy and electrification.
- Sustainable finance: NABERS supported the launch of Australia’s Sustainable Finance Taxonomy and released version 2 of the NABERS Sustainable Finance Criteria, helping align buildings with green investment benchmarks and streamlining access to sustainability-linked finance.
- Operational excellence: 11,000 ratings certified in FY25 (98% within 10 days), 86 new Assessors onboarded, and streamlined processes through NABERS Perform.
- Co-Assess expansion to Shopping Centres: Supporting sector leaders and streamlining the rating lodgement process to increase efficiency for both Assessors and NABERS internal team.
- Hotels sector recognition: NABERS Hotel ratings now visible on Google Travel with an “eco-certified” tag and accepted by Travalyst’s global sustainability platform.
- International growth: NABERS UK relaunched with strong uptake (42 new Design for Performance projects, 92 Assessors), while NABERS NZ grew 14% in Energy ratings and launched a Water rating tool for offices.
Sector expansion: Straighter pathways, sharper signals
FY25 marked the launch of the NABERS Embodied Carbon too – after 3 years of development and much anticipation from industry.
For the first time in Australia, there’s now a standardised way to measure and compare the carbon emissions from the materials and construction of new buildings.
NABERS worked closely with Green Building Council of Australia on this tool, so that embodied carbon can be measured consistently nationwide, helping the built environment set credible targets for the first time.
The tool empowers project teams to plan and deliver carbon reductions, while enabling policymakers to set meaningful targets. It’s a major step forward on the path to netzero.
Sector engagement: New pathways, greater visibility
From hotels and apartments to warehouses and schools, NABERS continues to expand its reach—creating clearer pathways and sharper signals for sustainability.
- Hotels go global - NABERS ratings now reach millions of travellers when they consider hotel bookings with NABERS Hotels certifications now recognised by Travalyst and, Google Travel. Work is underway to secure recognition on more booking sites.
- Electrification in apartments - In partnership with the ACT Government, NABERS explored electrification opportunities in 15 residential strata buildings in Canberra. Many buildings achieved 5 or 6 star NABERS Energy ratings, thanks to design features like decentralised ventilation systems, individual air-conditioning units and efficient car park ventilation.
