MECLA Spotlight on MECLA Guide to Low Carbon Concrete
In December 2025, MECLA’s working group on Concrete & Cement completed an updated version of the MECLA Guide to Low Carbon Concrete. The update includes an integration with the Low Carbon Materials Hub and a breakdown of different concrete classifications by state/territory.
The document gives guidance on what specifiers can expect when it comes to emissions from concrete at different compressive design strengths (MPa), and what type of questions they can ask to maximise sustainability outcomes when procuring. The document also aligns with the Cement Concrete & Aggregates Australia (CCAA)’s Australian Adoption of the GCCA – Global Cement and Concrete Association’s Global Ratings for Low Carbon and Near Zero Concrete guide that was launched late last year.
Speakers include:
- Evan Smith, National Sustainability Manager – Sustainable Construction at Holcim & Chair of the MECLA WG Concrete & Cement
- Michael Kilgariff, CEO, Cement Concrete & Aggregates Australia (CCAA)
- Matthew Kerley, National Technical Manager at Cement Australia (representing CCAA)
- Andrew Durant, Supply Chain Sustainability Strategy Lead, Laing O’Rourke
- Jason Bovis, Founder, Low Carbon Materials Hub
Presentations cover:
- The new local rating classification system that was adopted for the Australian context and launched late last year,
- An introduction to the updated Guide to Low Carbon Concrete as well as,
- A presentation on the adoption of low carbon concrete and
- A look into the Low Carbon Material Hub, which MECLA collaborated with for this version.
- There will also be an introduction in how to read an Environmental Product Declaration (EPD).
