Lodestellar is an independent quality review tool for Environmental Product Declarations (EPDs) in construction. Upload any EPD following EN 15804+A2 — draft or published — and receive a detailed, line-by-line quality report with actionable guidance. Reduce verification costs, fix issues early, and raise EPD quality efficiently.
Lodestellar is an independent, AI-assisted 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 upload their EPD in PDF or DOCX format and receive a detailed, line-by-line quality report with clear, actionable guidance on how to improve it. Lodestellar reviews EPDs against the requirements of ISO 14025, EN 15804+A2, and ISO 21930, as well as requirements commonly used by programme operators under the ECO Platform. Beyond compliance, it applies additional quality best practices covering transparency requirements, numerical consistency, and the overall coherence of reported values. Using Lodestellar as a pre-verification quality step helps teams catch issues early, reducing clarification rounds during formal verification, shortening timelines, lowering costs, and reducing compliance risk. Lodestellar is fully independent of any programme operator or LCA/EPD software provider, and is built by Lodestellar OÜ, an Estonia-based team combining an EPD verifier's LCA expertise with software engineering experience.
