Hi, in the UK we are using a LCA tool called IESVE IMPACT. It assess a total of 13 indicators (including those listed in the credit requirements) and follows the EN 15978 style life stage reporting standard. It takes into account: – Product stage (‘to gate’) – installation – In-use and – End of life Does anyone know whether or not IESVE IMPACT is an approved LCA tool for this credit?

The Reference Guide specifically mentioned Envest II as a good option for the UK. That doesn't mean IESVE IMPACT isn't good, but you don't mention whether the tool is capable of characterizing whole-building life cycle. As the Reference Guide notes, "Ensure that the selected tool can be applied at the whole-building level and produce results for the relevant indicators." I'm guessing your question may ultimately need to be answered by GBCI before you proceed too far.

That tool is based IMPACT database. I checked earlier this year the specifications for that, and one of the environmental impact categories uses a different characterisation method than listed as accepted ones (CML, ReCiPe and TRACI) in LEED v4 LCA Reference guide full text.
