Hardware requirements for openLCA vary based on LCA model complexity. For optimal performance, a faster processor and more RAM are recommended. Here are the minimum system requirements:

Windows

• CPU with 2 GHz or higher
• 6-20 GB RAM, depending on the background database and model size (6 GB for ecoinvent 2, 20 GB for PSILCA)
• 500 MB free hard disk space + space for databases (e.g. ecoinvent 3 requires ~250MB)

Linux

• CPU with 2 GHz or higher
• 5-15 GB RAM, depending on the background database and model size (6 GB for ecoinvent 2, 20 GB for PSILCA)500 MB free hard disk space + space for databases (e.g. ecoinvent 3 requires ~250MB)

macOS

• CPU with 2 GHz or higher
• 5-15 GB RAM, depending on the background database and model size (5 GB for ecoinvent 2, 15 GB for PSILCA)500 MB free hard disk space + space for databases (e.g. ecoinvent 3 requires ~250MB)
