The Data That Feeds EPDs

EPDs are only as good as the data behind them. This topic explores the databases and datasets that power EPDs—LCI libraries, electricity grid factors, transport routes and modes, manufacturing assumptions, and end-of-life scenarios—and how those inputs shape results, comparability, and confidence in the numbers.

When Data Stalls, Proxies Keep EPDs Moving
Supplier silence happens. Chinese New Year, line maintenance, contract handovers, even ERP cutovers can pause the energy, waste, or logistics data your life‑cycle model needs. Smart proxy data keeps modeling on schedule without corroding trust. The trick is knowing what can be safely approximated for now and what must be exact from day one, then documenting choices so reviewers nod and sales teams keep bids alive.

Global EPDs, local data, zero drag
Plant bills of materials rarely speak the same language. A tile line in Valencia logs pigments in Spanish with decimal commas. A sister plant in Tennessee writes the same inputs in English with periods. Both feed different ERPs. Verification teams do not have time to babysit spreadsheets. The fix is a pipeline that ingests multilingual, plant‑level data, normalizes units and formats, and outputs verifier‑ready datasets without slowing the schedule. That is how global EPD programs move at the speed commercial teams need.

End‑of‑life assumptions, harmonized for credible EPDs
End‑of‑life choices in EPDs are not side notes. They set the boundary for what happens when a product’s useful life ends, and they can swing results between versions even when the product itself hasn’t changed. The fix is simple but disciplined. Pick clear rules, document them, and keep them consistent across similar products so buyers can compare apples with apples.

ISO 14040 LCAs for the EU Battery Regulation
Battery carbon footprints now gate EU market access. The twist is that the required numbers are model‑ and plant‑specific, verified, and destined for a digital passport. Most manufacturers already hold 80% of what’s needed in ERPs, MES, EMS, and spreadsheets. The gap is structure, not existence. Build an LCA data pipeline that ingests messy factory reality and outputs ISO‑consistent results that can be refreshed without redoing the whole study.

Multi‑product plants rarely meter every line. Utility and wastewater totals live at the plant level, which stalls LCAs when teams chase SKU‑level data that does not exist.
