The updated ecoinvent 3.7.1 database is now available on openLCA Nexus.

This update was needed as the database provider had noticed an issue related to the iron sinter production dataset which included an error in the order of magnitude of the estimated emissions for dioxins and particulate matter (PM) – please find more details here: Known Data Issues | ecoinvent 3.7 – ecoinvent. This issue has now been corrected in version 3.7.1.

With this opportunity, the zinc mining dataset was also updated with newer data recently submitted by the International Zinc Association. Although the data were submitted outside of the review process of ecoinvent version 3.7, they are expected to significantly improve quality of the database. The newer data address the high extraction of gold modelled in the dataset until now and affect the results of the ecoinvent database calculated using mineral resource depletion indicators from most methods.
