ISO-14067

ISO 14067 CFP product carbon footprint LCA.

Définition

ISO 14067 cle requirements : (1) Functional Unit : explicit reference quantity (1 kg product, 1 km transported, 1 kWh delivered, etc.). (2) System Boundaries : cradle-to-grave (raw materials extraction -> manufacture -> distribution -> use -> end-of-life) vs cradle-to-gate (excludes use + end-of-life). (3) Data Quality : Foreground data (primary, from product manufacturer) + Background data (secondary, from LCA databases EcoInvent, GaBi, Sphera). (4) GWP characterization factors : IPCC AR5 100-year GWP standard (CO2 = 1, CH4 = 28, N2O = 265, etc.) ou recent AR6. (5) Allocation rules : when single process produces multiple co-products (e.g., petroleum refining), allocate emissions by mass, energy content, economic value. (6) Documentation : detailed methodology + data sources for reproducibility. EPD (Environmental Product Declaration) : standardized format publishing CFP results per ISO 14025 + ISO 14067, often industry-specific Product Category Rules (PCR). Adoption : construction industry (cement, steel manufacturers), consumer products (electronics, food + beverage), automotive (BEV vs ICE LCA studies).
