Mat 01 EPD uplift calculation

The methodology for calculating the EPD uplift requires use of the Responsible Sourcing of Materials search tool, available on the assessor extranet.

The Responsible Sourcing of Materials search tool will list the relative mass of each constituent material of a defined element as a percentage. However, due to an error on the system theΒ Responsible Sourcing of Materials search tool is currently referring to volume instead of mass.

This error will be resolved shortly. However for clarification in the interim, the EPD uplift calculation is based on mass, as per the methodology within the manual. The Responsible Sourcing of Materials search tool lists the relative mass of each constituent material of a defined element as a percentage, and until the tool is updated the term β€˜volume’ should be ignored.
