GreenCalculus — Ökobaudat Construction-Material Embodied-Carbon Factors by EN 15978 Module

292 EPD-derived embodied-carbon factors for 59 construction products across tenmaterial families — concrete, insulation, timber, glass, steel, brick, tile,plasterboard, paint and aluminium — reported by EN 15978 life-cycle module. Modules cover A1–A3 (product stage), B1 (use-stage carbonation), C1–C4 (end oflife) and D (benefits beyond the system boundary, reported separately and nevernetted into the A–C total). Derived from Ökobaudat 2024 (Release I), the Germanfederal LCA database published by BBSR/BMWSB and built from EN 15804 EPDs. Coverage gaps are preserved rather than filled: 31 of the 59 products carry nomodule C4, no concrete product has one, and the three aluminium entries coverend-of-life only. A missing module means the source publishes nothing for it —not zero. Timber product-stage values are negative because they carry biogeniccarbon storage, which module C3 releases again at end of life.
