  • Different approaches to measuring embodied carbon must be incorporated throughout the project to maximize carbon savings, starting at the business case.
  • Input-output LCA and process-based LCA are two methodologies used to measure embodied carbon, with input-output LCA providing macroeconomic carbon visibility and process-based LCA focusing on specific product impacts.
  • Australia is still in the early stages of developing EPDs, but there is an opportunity to combine different methodologies into a hybrid model.
