Cement EN 15804+A2 LCA and EPD generation
CEM I, II, III, IV and V types; clinker ratio, supplementary materials (fly ash, slag, limestone) — clca holds all cement variants in one model. EN 16908 PCR-aligned modulary table and verifier bundle.
Impact hotspots
A1–A3 — Clinker production and grinding
- A1 — limestone calcination (CaCO₃ → CaO + CO₂): process emission, ~60-65% of cement GWP
- A1 — fuel combustion (typically coal; alternative fuels can cut 30-40%)
- A3 — grinding electricity (typically 100 kWh/ton cement)
C — End of life
- C — concrete recycling has high uncertainty for the cement fraction
EN 15804+A2 modules
| Module | Modelling note |
|---|---|
| A1—A3 | Cradle-to-gate is the standard cement EPD scope (factory-gate FU: 1 ton). |
| A4 | Transport to site; road/rail/sea mode combination. |
| A5 | Reported at cement EPD level (not concrete); mixing/use loss. |
| C1—C4 | Often MND for stand-alone cement; cement share applied in concrete end-of-life accounting. |
| D | Contribution from CDW (construction & demolition waste) recycling. |
