There are many possible sources for life cycle assessment data. This page lists useful direct sources of data, as well as some lists of databases, that may be helpful to those conducting life cycle assessments (LCAs).

The list is not comprehensive, as there are many possible sources of the kind of data necessary to conduct LCAs, but it should be helpful in getting started. It is also in no particular order. If you would like to recommend a source to be added to this page, please contact us.
