Zipped version of the EF reference package to be used in in the context of EN 15804, including all the reference files, plus additional documentation, in ILCD structure. 

This version is based on the EF Reference Package 3.1. It includes also the configuration file for Look@LCI (see developer main page) for the specific package.

Compared to the EF reference package 3.1, the EN 15804 differs for the characterisation factors (CFs) of biogenic CO₂ uptake and emissions, which were set in the standard as equal to "-1" (CO₂ uptake) and "+1" (CO₂ release).

The Excel file reports the most relevant information contained in the zipped files: Flows, Methods, Characterisation Factors, Unit Groups and Flow Properties based on EF Reference Package 3.1
