EC3 User Guide

The EC3 User Guide provides an overview of the Embodied Carbon in Construction Calculator (EC3) Tool and provides answers to common questions. Due to the ever-changing nature of the tool, the User Guide is continually a work in progress.

For an illustration of  how EC3 compares EPDs and applies uncertainty, review EPD Uncertainty in Brief and the
EPD Uncertainty Adjusted GWP Calculator

LCA experts will also want to review the EC3 Uncertainty Methodology which describes how uncertainty and specificity are expressed in EC3.
