Description
The amended standard EN 15804 (2019) is used to calculate environmental indicators to use in Environmental Product Declaration (EPDs). The standard has just undergone national voting.
This update now requires user to work with the Environmental Footprint (EF) elementary flow list and impact methodologies EF 3.0 from the EU Commission, with the exception below.
Characterization
The specific characterization factors are a direct copy of the Environmental Footprint with one notable exception.
We recommend our customers to be cautious when drawing conclusions based on the results for the toxicity assessment methods (i.e. human toxicity cancer, human toxicity non-cancer, and freshwater eco-toxicity) as well as resource depletion (minerals and metals). The methodologies might not be robust and proficient enough, as well as are lacking application experience with widely used LCI databases, to make important decisions upon the results calculated with those impact assessment methods.
Normalization and weighting
Normalization and weighting is not applicable to EN 15804.

Description
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.
Characterization
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 (CaSO4·2H2O) is not characterized for the Sulphur content.
Normalization and weighting
Normalization and weighting is not performed.
