Carbon & Commercial Performance
Clear guidance on the NABERS Embodied Carbon Rating pathway, including how upfront embodied emissions are measured, assessed and reported for commercial buildings.
For developers, architects, contractors and sustainability teams seeking a recognised NABERS pathway for measuring and reporting upfront embodied carbon in commercial developments.
Discuss Your NABERS Embodied Carbon AssessmentIn Brief
A NABERS Embodied Carbon Rating provides a standardised methodology for measuring, assessing and reporting the upfront embodied emissions of eligible commercial building projects. Rather than evaluating operational energy use, the assessment focuses on emissions generated before a building begins operating, creating a recognised benchmark for consistent carbon disclosure across the commercial property sector.
Unlike a NABERS Energy Rating, which measures operational building performance after occupation, a NABERS Embodied Carbon Rating evaluates the emissions associated with construction materials, product manufacturing, transport and construction activities. Together these complementary NABERS assessment pathways provide a broader understanding of whole building carbon performance across both construction and operation.
As operational emissions continue to decline, upfront embodied emissions represent an increasingly significant component of commercial building performance. The NABERS framework provides a recognised and transparent methodology for measuring, communicating and benchmarking these emissions, supporting project reporting, performance disclosure and informed decision making throughout commercial developments.
The NABERS methodology measures upfront embodied emissions associated with construction materials, manufactured products, transport and construction activities for eligible commercial building projects.
It provides a recognised and consistent framework for communicating upfront embodied emissions alongside operational building performance, supporting greater transparency across commercial property.
NABERS Embodied Carbon supports commercial project reporting, performance disclosure, investor transparency and consistent communication of embodied emissions across eligible developments.

Project Relevance
A NABERS Embodied Carbon Rating may be relevant for commercial building projects seeking to measure, benchmark and report upfront embodied emissions through a recognised Australian framework. The pathway can support projects where embodied carbon performance, transparent disclosure or alignment with broader asset decarbonisation objectives forms part of the development brief.
New Developments
New commercial developments may pursue a NABERS Embodied Carbon Rating to establish and communicate the upfront emissions associated with materials, transport and construction before the building enters operation.
Major Works
Projects involving substantial new structure, façade, services or building fabric may need to determine whether the scope is suitable for assessment under the NABERS Embodied Carbon methodology.
Asset Strategy
Asset owners and developers may use a NABERS Embodied Carbon Rating to support carbon disclosure, portfolio strategy and clearer communication of upfront emissions performance.
Developers, asset owners, architects, engineers, quantity surveyors, contractors and sustainability consultants may each contribute project quantities, material information and supporting evidence required for the NABERS Embodied Carbon rating process.
NSW Planning Requirements
Under the NSW Sustainable Buildings SEPP, embodied emissions must be quantified and disclosed for certain non-residential developments. This statutory planning disclosure is not the same as obtaining a certified NABERS Embodied Carbon Rating, although the two pathways both involve information about materials and upfront building emissions.
New Non-Residential Buildings
The NSW requirements generally apply to development involving the erection of a new non-residential building where the estimated development cost is more than $5 million, subject to the scope and exclusions of the Sustainable Buildings SEPP.
Existing Non-Residential Buildings
Alterations, enlargements or extensions to an existing non-residential building may be captured where the estimated development cost is more than $10 million, subject to the applicable development scope and exclusions.
Project teams should confirm whether the development only requires embodied emissions disclosure for NSW planning purposes or whether a separate certified NABERS Embodied Carbon Rating is also being pursued for benchmarking, verification or asset reporting. An LCA or another carbon assessment pathway may also be required where it forms part of the project brief or an external rating framework.
Assessment Scope
The NABERS Embodied Carbon Rating measures the upfront embodied emissions associated with delivering an eligible commercial building. Using a defined assessment methodology, the rating evaluates the emissions generated before the building becomes operational, providing a consistent framework for benchmarking and reporting upfront carbon performance.
Building Materials
The assessment includes emissions associated with the manufacture of construction materials, building products and major building systems incorporated within the project.
Transport
Recognised transport assumptions contribute to the calculation of emissions associated with moving construction materials and products to the project.
Construction
The methodology also accounts for recognised construction-stage activities that contribute to the project's upfront embodied emissions before occupation.
A NABERS Embodied Carbon Rating is influenced by the quality of project information, including material quantities, product specifications, Environmental Product Declarations where available, recognised emission factors and construction data used within the assessment methodology. These inputs determine how consistently upfront embodied emissions can be measured, benchmarked and reported.
Carbon Performance
The NABERS Embodied Carbon Rating measures emissions associated with delivering a building before it begins operating, while operational carbon describes the emissions generated throughout the building's ongoing use. Together they provide complementary insights into different stages of a commercial building's carbon performance.
Operational performance is measured through the NABERS Energy Rating and other operational building performance pathways. These assessments focus on how efficiently a completed building performs in use, including energy consumption, building services and ongoing operational emissions.
The NABERS Embodied Carbon Rating complements this by measuring upfront embodied emissions associated with construction. Together, these assessment pathways provide a broader understanding of whole-building carbon performance without measuring the same aspect of a building's lifecycle.
Measures upfront embodied emissions associated with construction materials, product manufacture, transport and recognised construction activities before a building becomes operational.
Measures emissions generated while the building is occupied and operating, influenced by energy consumption, building services, controls, occupancy patterns and energy sources.
To learn more about operational building performance, explore our NABERS Knowledge Hub and NABERS Strategic, which explain operational ratings, benchmarking and ongoing building performance.
Whole Building Performance
The NABERS Embodied Carbon Rating measures the upfront emissions associated with delivering a commercial building, while operational performance is measured through ongoing building operation. Together these complementary assessment pathways help provide a more complete understanding of whole building carbon performance.
Considering both perspectives allows project teams and asset owners to understand the relationship between construction decisions made before occupation and operational performance achieved throughout the life of the building. Neither assessment replaces the other, but together they provide a broader view of building performance.
Upfront Performance
Measures the upfront embodied emissions associated with construction materials, product manufacture, transport and recognised construction activities before occupation.
Operational Performance
Operational performance reflects how efficiently a completed building performs through energy use, building services, controls and day-to-day operation.
Integrated Decision Making
Considering both assessment pathways supports more informed decisions about design, construction, asset performance and long-term commercial building decarbonisation.
The NABERS Embodied Carbon Rating focuses specifically on upfront embodied emissions. Operational building performance is addressed through NABERS Energy and related operational rating systems, while broader lifecycle modelling is covered by Life Cycle Assessment methodologies.
To explore full lifecycle modelling, visit our Life Cycle Assessment Knowledge Hub. For operational performance, see the NABERS Knowledge Hub.
Rating Context
The NABERS Embodied Carbon Rating brings greater visibility to the upfront emissions associated with delivering a commercial building. These emissions are linked to the materials, products, transport and construction activities assessed within the NABERS methodology and occur before operational performance can be measured.
Unlike operational emissions, which may be improved through building tuning, electrification, equipment upgrades and better controls, many upfront embodied emissions are committed once design, specification and procurement decisions have been implemented. Broader guidance on the origin and composition of these emissions is available in our Embodied Carbon Report Knowledge Hub.
Before Operation
The NABERS Embodied Carbon Rating measures recognised upfront emission sources before a building begins operating, creating a distinct reporting pathway from the operational performance covered in our NABERS Knowledge Hub.
Committed Impact
Once materials have been procured and installed, their associated emissions cannot usually be removed through later operational improvements. This makes the timing and quality of the assessment information important.
Project Decisions
Early coordination can improve the quality of quantities, product data and construction information used within the rating. Where broader option testing is required, a Life Cycle Assessment may provide a separate modelling pathway.
The NABERS Embodied Carbon Rating gives commercial project teams a recognised method for measuring, benchmarking and communicating upfront embodied emissions. Its practical value lies in converting project data into a consistent rating outcome that can support disclosure, comparison and asset-level carbon reporting.
Where embodied carbon results need to sit within a wider operational transition or portfolio strategy, explore our NABERS Strategic Knowledge Hub.
NABERS Assessment Inputs
A NABERS Embodied Carbon Rating is calculated from the physical inputs and recognised construction-stage emissions associated with delivering an eligible commercial building. Structural systems, façades, building services, finishes and other included elements contribute according to their quantities, product information and treatment under the NABERS methodology.
The rating outcome is therefore influenced by more than the total volume of materials used. Project quantities, specifications, Environmental Product Declarations, recognised emission factors, transport data and construction information all affect how accurately upfront embodied emissions can be assessed and reported. Our Embodied Carbon Report Knowledge Hub provides broader guidance on material carbon data outside the specific NABERS rating pathway.
Early coordination helps project teams identify the information required for the assessment before specifications, procurement packages and construction records become difficult to revise. This can improve evidence quality, reduce uncertainty and support a more reliable NABERS Embodied Carbon Rating without turning the rating itself into a detailed design optimisation exercise.
Measured quantities establish the scale of included structural, façade, services, finishes and other building elements used within the NABERS assessment.
Product specifications, verified EPDs and recognised emission factors provide the carbon data used to calculate and substantiate the rating outcome.
Recognised transport pathways, construction activities and project evidence contribute to the reported upfront emissions before building occupation.
Where a project requires comparative modelling of material options across a broader lifecycle scope, explore our Life Cycle Assessment Knowledge Hub. For operational building performance after occupation, see our NABERS Knowledge Hub.
NABERS Assessment Process
A NABERS Embodied Carbon assessment follows a defined methodology for collecting, classifying and evaluating the project information used to calculate upfront embodied emissions. The process brings together drawings, quantities, specifications, product data and construction evidence so the building can be assessed and reported through a consistent NABERS rating pathway.
Step 01
The project type, building scope, assessment stage and available evidence are reviewed to confirm how the development should be treated under the NABERS Embodied Carbon methodology.
Step 02
Drawings, schedules, specifications, quantity information and product records are reviewed and organised into the relevant building element and material categories required for the assessment.
Step 03
Material quantities, carbon data, transport information and construction inputs are applied through the rating framework, with supporting evidence reviewed before the final NABERS Embodied Carbon result is reported.
The reliability of a NABERS Embodied Carbon assessment depends on the completeness and consistency of the information supplied. Coordinated drawings, measured quantities, confirmed specifications, verified product data and clear construction records reduce uncertainty and strengthen the evidence supporting the rating outcome.
For broader guidance on material quantities, EPDs and carbon reporting inputs, visit our Embodied Carbon Report Knowledge Hub. Where the project requires comparative lifecycle modelling rather than a NABERS rating outcome, explore our Life Cycle Assessment Knowledge Hub.
Assessment Evidence
The reliability of a NABERS Embodied Carbon Rating depends on the quality of the project information supplied. Material quantities are combined with recognised carbon datasets, product information and supporting evidence so upfront embodied emissions can be assessed using the NABERS methodology.
Depending on the project, evidence may include Environmental Product Declarations (EPDs), recognised emission factors, product specifications, quantity schedules and construction documentation. Together these inputs support a consistent and transparent assessment process.
The NABERS methodology does not rely on a single source of carbon information. Instead, the assessment draws on the evidence available for the project to produce a robust and repeatable rating outcome. Further guidance on EPDs, emission factors and carbon datasets is available in our Embodied Carbon Report Knowledge Hub.
Measured quantities define the scale of building elements included within the NABERS Embodied Carbon assessment.
EPDs, recognised emission factors and verified product information provide the carbon evidence supporting the reported assessment.
Specifications, schedules and construction records demonstrate which products and systems are represented within the final rating.

Related Assessment Pathways
A NABERS Embodied Carbon Rating and a Life Cycle Assessment (LCA) are complementary assessment pathways, but they serve different purposes. A NABERS rating provides a recognised framework for measuring, benchmarking and reporting upfront embodied emissions for eligible commercial buildings, while an LCA is generally used for broader lifecycle modelling and environmental analysis.
Projects may undertake both assessments because they answer different questions. A NABERS Embodied Carbon Rating focuses on delivering a consistent and comparable rating outcome, whereas an LCA can support design optimisation, option comparisons and wider environmental assessment depending on the project objectives.
Neither assessment replaces the other. Instead, they provide different forms of evidence that may support planning, certification, sustainability reporting and commercial building decarbonisation. A detailed explanation of Life Cycle Assessment methodology is available in our Life Cycle Assessment Knowledge Hub.
Provides a recognised assessment methodology for measuring, benchmarking and reporting upfront embodied emissions for eligible commercial buildings.
Supports broader lifecycle modelling and environmental assessment where projects require analysis beyond the scope of a NABERS rating.
Many commercial developments use both assessment pathways to support design decisions, carbon reporting and long-term asset performance.
Explore our Life Cycle Assessment Knowledge Hub, Embodied Carbon Report Knowledge Hub and NABERS Strategic Knowledge Hub to understand how these assessment pathways complement one another.
Whole Building Performance
Commercial building performance is increasingly understood through multiple forms of measurement rather than a single rating. Operational efficiency, upfront embodied emissions and ongoing asset performance each describe different aspects of how a building performs throughout its life.
The NABERS Embodied Carbon Rating contributes one part of this wider performance picture by measuring and reporting the upfront emissions associated with delivering a commercial building. When considered alongside operational NABERS ratings, project teams gain a more complete understanding of building performance from construction through occupation.
Many projects therefore use complementary assessment pathways rather than relying on a single measure. A NABERS Embodied Carbon Rating supports recognised carbon reporting, while operational NABERS ratings, Life Cycle Assessment and broader sustainability initiatives each provide additional information for different project objectives.
Operational NABERS ratings measure how efficiently a building performs once occupied. Learn more in our NABERS Knowledge Hub.
The NABERS Embodied Carbon Rating measures the emissions associated with materials, transport and construction before the building begins operating.
Projects may also use Life Cycle Assessment or broader strategic planning depending on project objectives.
For long-term portfolio planning and operational improvement across commercial assets, explore our NABERS Strategic Knowledge Hub.
Assessment Coordination
Preparing a NABERS Embodied Carbon Rating requires information from multiple disciplines across a commercial building project. Architects, structural engineers, building services engineers, quantity surveyors, contractors and sustainability consultants each contribute information that supports the assessment methodology.
Rather than influencing design decisions directly, the assessment relies on coordinated project documentation, measured quantities, product information and construction records to produce a reliable and transparent rating outcome. Well-organised project information generally improves both assessment efficiency and reporting confidence.
Projects that coordinate assessment inputs throughout design and construction are typically better prepared for carbon reporting, while projects requiring broader design optimisation may also undertake an Life Cycle Assessment or prepare an Embodied Carbon Report depending on project requirements.
Drawings, specifications and schedules establish the scope of the NABERS Embodied Carbon assessment.
Measured quantities, product information and supporting evidence provide the data used to calculate and verify the rating.
Bringing project information together throughout delivery helps produce a more complete and consistent NABERS Embodied Carbon Rating.
Learn more about Embodied Carbon Reports, Life Cycle Assessment and NABERS Strategic to see how carbon reporting fits within the broader commercial building performance ecosystem.
