Use Guide: OpenLCA (Recommended)


  • TianGong LCA data recommends using the open-source, free software OpenLCA. Based on our experiments, OpenLCA is the most compatible with ILCD format and has the strongest import-export functionality.

  • Compared to proprietary software like SimaPro and GaBi, OpenLCA does not have significant data migration barriers. Its data compatibility and transferability are relatively good. TianGong database will prioritize support for OpenLCA.

  • Please follow these steps to use OpenLCA to open the TianGong LCA database. If you encounter any issues, please contact
