  1. 60. From LCA Database to AI-Enabled LCA Infrastructure
    Jianchuan Qi, Xiaohui Lu (Tsinghua University)
    23/09/2026, 10:15
    Open Data
    Presentation (slides)

    Highlights / Discussion Points

    • TianGong starts from building a Chinese LCA database and extends toward broader LCA infrastructure.
    • The infrastructure connects database development with data structuring, review, calculation, interoperability, and reuse.
    • AI is used within controlled, auditable workflows to support data curation and quality governance.
    • This approach can help...

  2. 63. ElecImpact: An Open, Modular, Graph-Based Platform for Collaborative Construction of Life- Cycle Inventory Data
    Vincent Corlay (Mitsubishi Electric R&D Centre Europe, Rennes, France)

    Open Tools and Development

    Highlights / Discussion points

    Takeaway: ElecImpact provides a graph-based data structure that makes life-cycle inventory (LCI) data and models reusable, traceable, and directly interoperable with existing tools such as Brightway. The code lives in a multi-package monorepo, and the data lives in a separate repository.
    Open modular tools: ElecImpact is fully open source under a...

  3. 26. naKnow: a collaborative initiative to bridge data gaps in ICT life cycle assessment using parametric modelling

    Presentation (slides)

    The ICT sector still struggles to fully understand its environmental footprint. LCA can help in assessing it, but is currently hindered by the lack of open, trustworthy, and quality data, which can be explained by two elements: 1) a complex supply chain, and 2) business secrecy in a competitive environment.

    In this presentation, the objective is first to present naKnow: a collaborative...

  4. 27. Reproducing Agribalyse 3.2 in Brightway: an open pipeline for matching, scoring, and SimaPro parity

    Open Tools and Development
    Presentation (slides)

    Agribalyse is one of the most widely used public food LCA databases, but reproducing its SimaPro-based results in Brightway is not a simple CSV import. The source data arrive with SimaPro elementary-flow conventions, adapted EF 3.1 characterization factors, background datasets copied or renamed across ecoinvent versions, unit drift, and waste-treatment modelling conventions. This creates a...

  5. 6. TRAILS: Deeply Temporalised Life Cycle Assessment with Climate Emulator Coupling
    Romain Sacchi (PSI)
    23/09/2026, 11:30
    Open Tools and Development
    Presentation (with notebook)

    We present TRAILS, an open-source Python framework for time-explicit life cycle assessment (LCA) that enables deep temporalization of product systems. Rather than representing the technosphere as a collection of year-specific, independent two-dimensional matrices, TRAILS treats it as an interconnected temporal structure (i.e., a three-dimensional tensor) in which processes and exchanges can be...

  7. 52. Connecting national EPD databases to the Brightway ecosystem: a worked example with lcpy and NZGBC
    Ehsan Anvari (PhD researcher, AUT university)
    Open Data
    Presentation (with notebook)

    Context. A growing number of national green-building councils publish open EPD databases that provide pre-characterised GWP values per EN 15978 lifecycle module — the NZGBC Embodied Carbon Database in New Zealand, EPiC in Australia, ICE in the UK, ÖKOBAUDAT in Germany. These databases are explicitly designed to be open to any tool provider, yet they sit outside the elementary-flow paradigm on...
