A Lendlease project team sends through a sustainability requirement: they need the emissions behind your work, or the materials you supply, as part of their Scope 3 Emissions Protocol. 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 Lendlease. This guide explains their publicly stated Scope 3 Emissions Protocol, 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 Lendlease is asking
About 90% of Lendlease's emissions are Scope 3, mostly the manufacture of building materials upstream and building energy use downstream. Its Absolute Zero by 2040 target cannot be met from its own operations alone, so the Scope 3 Emissions Protocol sets out which value-chain categories count, and Lendlease is building a data-sharing ecosystem to exchange product-level emissions data across its supply chain. The Supplier Code of Conduct also asks suppliers to minimise their emissions and educate their own supply chains.
What Lendlease 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 subcontractor on site | The emissions of the work you perform, fuel and plant first |
| Any supplier | To minimise emissions and report under the Supplier Code of Conduct |
Embodied carbon is the number they want
In construction 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 subcontractor 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. Stockland is asking its contractors and suppliers along the same lines.
“Lendlease is moving to structured, product-level data, not a one-line total. A figure you can trace to its method is the one that survives into their protocol.”
What the data-sharing ecosystem means for youHow to respond
A first response to a Lendlease 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
