A fixed, citable snapshot of the list. Download the files, or cite the release so others get exactly the same data.
Files
Which file do I need?The published list itself: one record per elementary flow, with its substance, its context, its identifiers and the source rows it carries.
What each implementation of a method says about each flow: the categories, the factors and which implementation states them.
Where two implementations of one method disagree, and where one skips a context of a substance the other characterises.
Everything this application reads: the flows, the flow objects, the change log, the merge outcomes and the factors, in one file.
3.8 GB. The whole build, so expect a long download and that much free disk space.
Some fields come from source lists published under their own licences. Every source list this one is built from is either in the public domain -- the GLAD mapping files, which is how the ecoinvent and SimaPro names reach this list -- or published under the same Open Database Licence this list uses, as ecoinvent's glossary is. No field here carries terms stricter than ODbL-1.0. Licence and reuse
