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. The current Chair of WG2 is Caroline Noller, CEO and Founder at The Footprint Company. The Co-Chair is Lauren Howe, Senior Materials Engineer at ARUP.

Over the past year, WG2 has produced a discussion paper reviewing the various quantification approaches to embodied carbon. It is not the intention of MECLA 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
