Life Cycle Assessment Commons

Quick Start Guide

The LCA Commons provides life cycle assessment (LCA) data in the form of unit or system process life cycle inventory repositories, input-output (I/O) repositories, background repositories that support the Federal LCA Commons, life cycle impact assessment (LCIA) methods that are compatible with data on the LCA Commons, and legacy repositories that contain data but are no longer maintained. 

Two forms of LCIA methods are available: with flows and without flows. To access the version with flows, use the repositories found here: https://www.lcacommons.gov/lca-collaboration/. The versions without flows can be accessed at this link https://www.lcacommons.gov/lcia-methods-without-flows or under the 'Data' tab. To learn more about available resources and to access trainings and tools for the Federal LCA Commons please visit ‘FLCAC Resources’ under the ‘Documentation’ tab.

The data on this site is free to download, no login or account is necessary. These data products are intended to be used in Life Cycle Assessment studies and require further analysis and modeling to produce LCA results. 

Below are some quick tips on getting started:

  • To read about the purpose of the Federal LCA Commons visit the ‘About Us’ tab above.
  • Repository release notifications are located on the home page.
  • Select ‘Browse Repositories’ to access LCI and LCIA data.
  • The ‘Documentation’ tab above provides resources for using the data and the public API.
