About fpLCA

fpLCA is a Life Cycle Assessment engine that turns LCA databases into inspectable, queryable answers — fast.

It loads EcoSpold2, EcoSpold1, and SimaPro CSV databases, builds supply chain dependency trees, computes life cycle inventories using sparse matrix algebra, and applies characterization methods for impact assessment.

What It Does

Browse activities and flows across multiple databases
Explore supply chain trees and force-directed dependency graphs
Compute life cycle inventories (LCI) and impact scores (LCIA)
Link databases across nomenclatures (e.g., Agribalyse referencing Ecoinvent)
Upload your own databases via the web UI, without touching config files

Key Features

Multiple database formats: EcoSpold2 (.spold), EcoSpold1 (.xml), SimaPro CSV
Archive support: Load databases directly from .zip, .7z, .gz, or .xz archives — no manual extraction needed
Cross-database linking: Resolve supplier references across databases, with configurable dependencies and topological load ordering
Web interface: Multi-page Elm app with search, tree view, graph view, inventory, LCIA, and database management
Desktop application: Native Windows/Linux app — no installation or configuration needed
REST API and CLI: Scriptable interface for automation and integration
Fast cache: Per-database cache with automatic schema-based invalidation; loading the last version of Ecoinvent goes from under a minute cold to a few seconds cached.
Optional access control: Single-code login with cookie-based session
