Using Australasian EPDs in the Infrastructure Sustainability (IS) Rating Scheme

An informative webinar exploring the IS Rating Scheme and how Australasian EPDs can be used in the assessment process.

This webinar/event was held on: August 20, 2025

The IS Rating Scheme is Australia and New Zealand’s rating framework for assessing the sustainability of infrastructure. EPDs are a crucial part of quantifying baseline environmental impacts and improvements across multiple phases of construction and end-of-life.

The webinar brought together insights from across the infrastructure sector – Tyrel Momberg from the Infrastructure Sustainability Council, Ishan Jain from manufacturer BlueScope, and Ross Brookshaw from the M80 Ring Road Completion project, sharing the end-user perspective – to explain how EPDs can be used to measure and reduce impacts, supporting more sustainable construction.

The webinar explored the following topics:

How the IS Materials Calculator uses EPD data to measure circular economy and embodied carbon improvements
The benefits of EPDs to BlueScope, and how they are being used both internally and across the supply chain to drive improvements – including Scope 3 emissions
How EPDs support education on the whole-of-life story of products, and their role in IS Rating v2.1 Rso-6 and Ene-1 credits
