EPD verificada por tercero RTS_180_22 (EN 15804+A2, RTS Finlandia; LCA por Natural Resources Institute Finland/Luke; válida 13-05-2022 → 12-05-2028). GWP-total A1–A3 (cradle-to-gate): −1,34 a −1,37 kg CO₂eq/kg (Planed Thermowood D/S) y −1,43/−1,46 (Rough Thermo Timber D/S). Carbono biogénico almacenado ≈1,8 kg CO₂/kg (0,49 kg C/kg). Densidad EPD: 390 kg/m³ (cepillado) / 430 (bruto). El A1–A3 negativo se debe al carbono biogénico almacenado, que se libera en el fin de vida (C3). CO₂ secuestrado ≈701 kg/m³ calculado sobre densidad cepillado 390 kg/m³.
