The Embodied Carbon in Construction Calculator (EC3) tool from the Carbon Leadership Forum (CLF) and industry partners is designed to enable the building industry to transparently measure, compare, and reduce embodied carbon emissions from construction materials.
How the EC3 methodology uses EPD data: Using the global warming potential (embodied carbon) results from the manufacturing life cycle stage, five attributes of the data are evaluated to determine its variability. Is it: MFR specific, plant specific, product specific, current process data, supply-chain specific or public datasets? Applying a ‘burden of the doubt’ calculation (opposite of ‘benefit of the doubt’ when the best outcome is given without proof), a +/- uncertainty value (penalty) is added based on yes/no. When the data is not in the EPD, an uncertainty value is applied.
NOTE: Results are not precise, they are directionally correct and should be used with in that in mind. Results may not always identify low embodied carbon products due to non-specific data in the EPD.

Cannot be identified to be among the 80% of related products with the lowest EC and may be in the 20% highest due to high reported EC results plus some high uncertainty.
Not known to be among the 60% of related products with the lowest EC, but likely not in the 20% highest. Uncertainty may be high due to mostly non-specific data in the EPD. Industry-wide EPDs are assumed to be in this range.

When there is no EC3 result for an EPD: Data is shown only for EPDs that have been successfully digitized by EC3 and for which sufficient category data is available. Read the EC3 methodology.
