EN 15804 and NF EN 15804


The standard EN 15804 is used to calculate environmental indicators to use in Environmental Product Declaration (EPDs).

The introduction of EN 15804 as a separate group of characterization factors is meant to align more specifically to the EN 15804 standard without additional calculations done by thinkstep as is the case with the CML values.

The NF additional values are living up to the French additional characterizations to the EN 15804 norm.


ADP fossil is still calculated depending on the characterization factor relating directly to the net calorific value of the fuels.

ADPe are not calculated for composites and minerals where the mining operation is not the active route used, e.g. gypsum (CaSO4ยท2H2O) is not characterized for the Sulphur content.

The entire set of additional NF EN 15804 values are included.

Normalisation and weighting

Normalization and weighting is not performed.
