Cradle to Gate Embodied Carbon

When you discuss embodied carbon, people generally want material has the least embodied carbon and that included me. Having started to read into whole life carbon, I understand that the product stage (cradle to gate, A1-A3) is just part of it. What happens through the life of the building, has a large impact.

But I think people need to understand the differences in scale to start having those discussions. So, I made this small diagram of the main materials and their embodied carbon per meter cubed.

Often it is shown as per kg, but I wanted to be able to size elements and be able to convert them to embodied carbon without having to find their densities.

I still feel like I’ve only scratched the surface of this.
