Lodestellar

Lodestellar is an independent quality review tool for Environmental Product Declarations (EPDs) in the construction sector. It helps EPD professionals, LCA consultants, manufacturers, and programme operators create higher quality EPDs more efficiently — and better understand any EPD already on the market.

The tool works with any EPD that follows the EN 15804+A2 standard, whether it's an early draft or a fully published document. Users simply upload their EPD in PDF, DOCX, PowerPoint, or Excel format, and Lodestellar returns a detailed, line-by-line quality report with clear, actionable guidance on how to improve it.

What Lodestellar checks

Lodestellar reviews EPDs against the requirements of ISO 14025 and EN 15804+A2, as well as requirements commonly used by programme operators operating under the ECO Platform. Beyond compliance, it also applies additional quality best practices that help EPDs meet a consistently high standard. The review covers transparency requirements, numerical consistency, and the overall coherence of reported values — going deeper than what general-purpose AI tools or manual checks typically catch.

Key benefits for EPD teams

Using Lodestellar as a pre-verification quality review step helps teams identify and fix potential issues early in the EPD development process. This leads to fewer clarification rounds during verification, shorter timescales, lower costs, and reduced compliance risk. It also gives stakeholders early confidence in EPD quality, which can support commercial discussions and project decisions while verification is still underway.

Because Lodestellar provides clear explanations alongside its feedback, it also serves as an EPD literacy tool — making quality understandable to team members beyond just LCA specialists.

Independent and affordable

Lodestellar is fully independent of any programme operator and any LCA or EPD software provider. It offers a dedicated, purpose-built approach to EPD quality that complements existing workflows rather than replacing professional verification.
