Embodied Emissions

Embodied carbon refers to the carbon emissions released throughout the entire process of constructing a building. This includes the extraction of raw materials, the manufacturing and refining of materials, transportation, installation, and even the disposal of old supplies. All of these stages contribute to the production of embodied carbon emissions.

As outlined by the NSW SEPP all new residential and non-residential applicants from 1 October 2023 will be required to disclose the quantities of materials and associated embodied emissions when applying for a development application and a construction certificate.





Embodied Emissions Reports

The NSW government's State Environment Planning Policy (Sustainable Building SEPP) 2022 SE SEPP introduced embodied emissions measures and reporting for all types and associated materials.

NABERS Embodied Emissions Tool will be the required format for non-residential developments before mid-2024.  Between October 2023 and mid-2024, the interim instrument is the NABERS Embodied Emission Material Form.



Materials Form

The Embodied Emission Material form captures the breakdown of proposed material used in non-residential developments. It makes a comparison of potential carbon emissions between proposed buildings on a similar scale if possible. The Embodied Emission Material form could also serve as a baseline for selecting lower carbon-intensive materials from its comprehensive list of materials.


Residential Building Emission reporting 

Have you got a residential project? A new Material Index has been introduced to the Building Sustainability Index (BASIX) to calculate and report on embodied emissions.

We would love to talk to you about your project. Let's start our journey here


How is it assessed? 

Accredited NABERS Assessors audit the architectural and engineering documentation package and extract quantities of materials. This is then curated and entered into the Embodied Emission Material form. The proposed building is broken down into the following four categories:

1. Structure

2. Envelop

3. Permanent internal walls and doors

4. Services

5. External works

Whenever possible, the direct cost of material to construct the building. and permanent elements of the proposed building will be recorded. Labour or equipments should not be accounted for.

The catchment for materials recorded should cover at least 80% of the total bill of materials. 


Below is a Step by Step illustration of how embodied energy of materials are quantified and reported in Worksheet 2 of the  Embodied Emissions Materials Form.

Step 1, Our technicians model the proposed development.

Step 2, The proposed development will then be broken down into Structure/Envelop/Permanent Walls and Doors/External Works.

Concrete elements 492-1

Roof 492Fig. 3 Isolate Envelop (Metal roofing steel in square meter, Lift shown for scale)

Walls 492

Fig. 4 Permanent Internal walls ( in square meters) and doors/windows (quantity in numbers)

Step 3, The quantities of materials from our model will then be entered to the corresponding section in the Embodied Emissions Material Form.

The Embodied Emission Materials Form will be used until the rollout of the National Embodied Emission Tool in May 2024. 
All non-residential developments are required to be completed from 1st October 2023.
As a bonus, NABERS has also included embodied emissions in the Agreement to Tare as optional for large commercial developments that wish to demonstrate leadership in decarbonisation.

Embodied Emissions Report FAQ's

  • What is an Embodied Emissions Report?

    An Embodied Emissions Report outlines the quantities of key materials and associated embodied emissions throughout the entire process of constructing a building.

  • When is an Embodied Emissions Report required?

    As of 1 October 2023, all new residential and all non-residential developments are required to submit an Embodied Emissions Report at the Development application and Construction Certificate stages.

  • What is the cost of an Embodied Emissions Report?

    The cost of an embodied emissions report can range between 2-4.5k depending on the size of your project.

  • How are Embodied Emissions reported?

    For residential developments, a new Material Index was introduced by the State in the Building Sustainability Index (BASIX) to calculate and report the embodied emissions of construction materials in new developments.

    For all non-residential developments, a NABERS Embodied Emissions Material Form must be completed, with material quantities (and later embodied emissions) to be calculated at the development application stage and again at the construction certificate stage. The form is an interim reporting tool until the NABERS Embodied Emissions Framework and related online tools are released in mid-2024.
