Learn how to calculate embodied carbon and take your first step towards reducing the carbon emissions associated with your designs.

Listen to an overview of the IStructE’s new guide on how to calculate embodied carbon for structural engineers. Presenters outline the background and purpose of the guide, explain how you can apply the calculations to your own projects and give a worked example.

Learning outcomes

  • An understanding of the importance of embodied carbon
  • How to calculate the embodied carbon of a structural design

  • An appreciation of the uncertainty and limitations behind embodied carbon calculations

  • How to critically analyse design decisions using embodied carbon calculations

  • How to present and report embodied carbon calculations

Intended for

Members and non-members. Some content is UK-focused, but the principles of the guide are internationally applicable.
