Dexus Asked for Your Scope 3 Data. Here's How to Respond.

3 min read

A Dexus development or fit-out team sends through a sustainability requirement: they need the emissions behind your work, or the materials you supply, for their absolute Scope 3 target. Two questions follow: what counts, and how do you give them something that holds up?

About this guide

CO2 Lab is not affiliated with, endorsed by, or partnered with Dexus. This guide explains their publicly stated science-based targets and supplier engagement, as at October 2026, to help suppliers respond, and is based on the sources linked below. All trademarks are the property of their respective owners.

Why Dexus is asking

Dexus has science-based targets to cut absolute Scope 1 and 2 emissions by 70% and absolute Scope 3 emissions by 25% by 2030, from a 2018 baseline. Because the Scope 3 target is absolute rather than intensity-based, reductions in the value chain count directly towards it. The biggest line is embodied carbon in developments and fit-outs, so Dexus reviews upfront carbon across developments, fit-outs and procurement, and designs out emissions through reuse, such as its Forever Fitout model. Contractor and materials data is central to that.

What Dexus asks, by supplier type

If you areWhat they'll want from you
A materials supplier (concrete, steel)Product-level embodied-carbon data, ideally from an EPD
A fit-out or contractor supplierThe emissions of the work you perform, and reuse where it applies
A tenantEnergy use and the emissions of works within the space

Embodied carbon is the number they want

An absolute Scope 3 target puts the weight on the value chain, and in property the biggest lever is embodied carbon, the emissions locked into materials when they are made. Concrete and steel dominate it. So a materials supplier faces the most specific ask: the emissions per unit of product. A fit-out or contractor supplier is asked for the emissions of the work performed, and for reuse where models like Forever Fitout apply. Either way it is the same discipline as any customer's data request: a number with the method behind it.

“An absolute target cannot be met by growing more efficiently: the tonnes have to fall. A figure you can trace to its method is the one that survives into Dexus's account.”

Why your number matters to Dexus

How to respond

A first response to a Dexus request

  • Build Scope 1 and 2 from your fuel, plant and energy records
  • For materials, work out emissions per unit of product supplied
  • Note reuse or recycled content where it applies, with evidence
  • Apply the current NGA Factors and recognised materials data, method shown
  • Keep the evidence together, so a product-level figure is defensible

Turn the Dexus request into a traceable number. What our AI Sustainability Analyst gives a contractor or supplier:

Reads what you hold
Fuel, plant and energy records already on file, no new data collection to get started.
Calculates your scopes
Scope 1 and 2 against the current NGA Factors, with the method shown alongside each figure.
Shows the working
Source, factor and reasoning behind each number, ready for a product-level data request.
Becomes your baseline
The same pack is your own starting point the day you report in your own right.

Answer the Scope 3 request with something traceable

Our AI Sustainability Analyst builds your footprint from your own fuel, plant and energy records, with the method and evidence behind every figure, ready to share.

Frequently asked questions

Does Dexus require its suppliers to report emissions?+

Dexus has science-based targets to cut absolute Scope 1 and 2 emissions 70% and Scope 3 emissions 25% by 2030, and its biggest Scope 3 line is embodied carbon. Materials suppliers and contractors on its developments face the most specific data requests.

What is Dexus's Scope 3 target?+

Dexus has science-based targets to reduce absolute Scope 1 and 2 emissions by 70% and absolute Scope 3 emissions by 25% by 2030, from a 2018 baseline, and net zero across all scopes by 2050. Because the Scope 3 target is absolute, not intensity, reductions in the value chain matter directly, which is why supplier data is central.

I'm a fit-out or contractor supplier to Dexus. What do I need to provide?+

Expect to be asked for the emissions of the work you perform and the materials you supply. Dexus reviews upfront carbon in developments, fit-outs and procurement, so the request reaches fit-out and contractor suppliers as well as materials. The starting point is your own Scope 1 and 2, built from records you already keep.

What is the Forever Fitout model, and why does it matter to me?+

Forever Fitout delivers a ready-to-occupy workplace using modular components designed for reuse across tenancies rather than demolition at lease end. It is how Dexus designs out embodied carbon, so if you supply fit-outs, expect questions about reuse and the emissions of what you provide, with the method behind the figures.
