EPD Generator

Generate EN 15804+A2 EPDs in hours, not weeks

The clca EPD generator automates the path from product data to a ready EN 15804+A2 Tables 8-11 report. An AI assistant trained on LCA and EPD writes the interpretation, ecoinvent v3.12 mapping is one click, the mass-flow balance updates live, and the verifier bundle exports in one click.

How it works

  1. 1

    Enter product and company data

    Functional unit, declared unit, reference service life and company data. Pick the Product Category Rule (PCR).

  2. 2

    Model the life cycle inventory

    A1-A3 raw materials + manufacturing, A4-A5 construction, B1-B7 use, C1-C4 end of life, D benefit. One-click ecoinvent mapping with auto geography/technology/time consistency checks.

  3. 3

    Impact assessment (LCIA)

    Standard LCIA methods (CML v4.8 2016, EF v3.0/3.1, IPCC 2013, IMPACT World+) or your own custom method. 23+ category results auto-distributed across the modulary table.

  4. 4

    Data quality and sensitivity

    DQR (data quality rating) scored 1-5 via Pedigree matrix. Automatic ±10% sensitivity scenario on inventory items with DQR > 3.5.

  5. 5

    AI-assisted interpretation

    An AI assistant trained on LCA and EPD reads the dominance analysis, identifies hotspots and drafts the EN 15804+A2 interpretation section. You approve or edit it — turning hours of manual writing into minutes.

  6. 6

    Ready report & EPD output

    A ready EN 15804+A2 EPD template generates as PDF in one click; machine-readable JSON-LD and the verifier traceability bundle ship automatically alongside. LCA copy lets you produce the second report in minutes for a product variant.

  7. 7

    Hand off to the verifier

    Full audit log + raw inventory export for the independent third-party verifier. JSON and XML formats for program operators like ITB, IBU, EPD International.

FAQ

How long does an EPD take to generate?

A typical EPD on clca takes 1-4 weeks. Automatic ecoinvent mapping and template filling cut the time to 1/3 of a traditional workflow. Independent verification adds 2-6 weeks depending on the program operator.

Which PCRs does it support?

EN 15804+A2 (the core PCR for construction products), ITB EPD PCRs, IBU PCR Part B (category-specific), EN 16757 (concrete), EN 16783 (insulation), EN 16908 (cement) and PEFCR drafts.

Which LCIA methods are supported?

CML v4.8 2016, EF v3.0/3.1, IPCC 2013, IMPACT World+, EPS 2020d, Cumulative Energy Demand and Ecological Footprint. You can also build a custom blended method.

How does the AI report assistant work?

A built-in AI assistant reads your LCA output (dominance analysis, sensitivity, modulary table) and drafts the EN 15804+A2 interpretation section. It identifies hotspots and proposes industry best-practice phrasing. You approve or edit — the final word is always yours. Every generation is written to an audit log the verifier can inspect.

What is the licensing model?

Per-project licensing is available — pay only for active EPD/LCA projects. For consultancies, the consultant module manages multiple client portfolios from one panel. Universities get up to 50% academic discount.
