MECLA Working
Group 2 - Evaluation

Working Group 2 – Evaluation (WG2) is consortium of knowledge experts contributing to the advancement of embodied carbon measurement and benchmarking for materials, building and infrastructure. The working group analyses the opportunities and challenges in using different methodologies for benchmarking embodied carbon, creating assets industry can use to better understand the current state of play. WG2 is now chaired by Rocio Rutter, National Head of Growth and Advisory at pitt&sherry.

"Measuring embodied carbon is a system's exercise. We must understand the parts, the whole, and key areas for intervention. There is no one-size-fits-all solution, but establishing a common language and standardised process for measurement, benchmarking, and reporting is crucial. Similarly, ensuring data reliability and developing industry-level databases are essential next steps. This is an exciting time to co-design our sustainable & circular future."

Embodied / Upfront carbon measurement and benchmarking is in a dynamic state, which is evident from the information presented in this document. A critical goal for the sector is to evolve measurement approaches that allow for consistent, comparable and reliable benchmarking – or sufficient capacity in the sector to make adjustments to achieve suitable comparability. The goal of “apples for apples” comparability has been central to cost consulting aims for decades. The development of operating carbon measurement and benchmarking has also evolved over a decade. For the industry to succeed in achieving deep reductions in a timely manner, measurement and metrics are essential.

MECLA WG2 plays a crucial role in the Australian ecosystem, bringing together industry, research and government representatives from 100+ organisations. Currently, the WG meets quarterly to discuss the current state of measurement and evaluation in Australia.

MECLA WG2 Discussion Paper

In 2022 WG2 produced a discussion paper reviewing the various quantification approaches to embodied carbon. The intention of MECLA is not to indentify a preferred benchmark method. The aim is to provide a review of available options for benchmarking performance. The method that is preferred by a user will depend on the information they have available, the stage of design and consistency with other embodied carbon calculation methods in use by the individual/organisation.

To create this document WG2 was divided into four sub-task groups in order to:

  • Identify and map the hierarchy and relationship of relevant embodied carbon “Standards” & definition myth busting

  • Research empirical methods for benchmarking dealing with all methods of LCA for ease of benchmarking in the user context

  • Define best suited “comparable” units suitable at a material and building scale, compare to current practice

  • Compile an inventory of calculation tools and life cycle inventory data and profile suitability to Australia
