A Stockland development team sends through a sustainability requirement: they need the emissions behind your work, or the materials you supply, to feed their 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 Stockland. This guide explains their publicly stated Scope 3 target and supplier engagement, as at October 2026, to help suppliers respond, and is based on the sources linked below.

Why Stockland is asking
Stockland has already reached net zero Scope 1 and 2 emissions, so its remaining reductions have to come from the value chain. It is targeting a 50% reduction in the intensity of its most material Scope 3 emissions by 2030, working with suppliers and tenants to decarbonise. In property development the most material line is embodied carbon, the emissions in the materials a project is built from, so contractor and materials data is central to the target.
What Stockland asks, by supplier type
| If you are | What they'll want from you |
|---|---|
| A materials supplier (concrete, steel) | Product-level embodied-carbon data, ideally from an EPD |
| A contractor on site | The emissions of the work you perform, fuel and plant first |
| A tenant or fit-out partner | Energy use and the emissions of works within the space |
Embodied carbon is the number they want
In property the biggest lever is embodied carbon, the emissions locked into materials when they are made, and concrete and steel dominate it. So a materials supplier faces the most specific ask: the emissions per unit of product. A contractor is asked for the emissions of the work performed, which is fuel and plant first. Either way it is the same discipline as any customer's data request: a number with the method behind it.
“With Scope 1 and 2 already at net zero, the value chain is the whole game. A figure you can trace to its method is the one that survives into their target.”
Why your number matters to StocklandHow to respond
A first response to a Stockland request
- Build Scope 1 and 2 from your fuel, plant and energy records
- For materials, work out emissions per unit of product supplied
- Apply the current NGA Factors and recognised materials data, method shown
- Flag what is measured and what is estimated
- Keep the evidence together, so a product-level figure is defensible
