EPD Parser
A Claude Code skill that parses Environmental Product Declaration PDFs — extracting GWP, life cycle stages, program operator metadata, and LEED eligibility into a standardized 42-column schema.
What it does
Type /epd-parser with one or more EPD PDF files. The skill extracts text via PyMuPDF, parses impact indicator tables, and structures the data into a 42-column schema covering product identity, EPD metadata, environmental impacts across life cycle stages, resource use, and LEED eligibility.
Handles EN 15804+A1 and +A2 formats, multi-product EPDs, non-English documents, and varying table layouts across program operators (UL, NSF, Environdec, IBU, ASTM).

/epd-parser ~/Documents/project-epds/What it extracts
- Product identity — manufacturer, product name, declared unit, CSI division
- EPD metadata — registration number, program operator, PCR, standard version, validity dates, system boundary
- Impact indicators — GWP-total, GWP-fossil, GWP-biogenic (A1-A3), plus A4-A5, B1-B7, C1-C4, D when available
- Additional impacts — ODP, AP, EP, POCP
- Resource use — renewable/non-renewable primary energy, fresh water, recycled content, waste
- LEED eligibility — flags product-specific vs. industry-average, third-party verification status
