This EPD covers the Aluminum under the brand Hydro 4,0. The primary Aluminum used in the products is produced based on renewable power production in Norway, ensuring maximum Carbon footprint of 4,0 tons CO2-eq/ton Aluminium. The carbon footprint of the Aluminum is calculated on individual batches, and the methodology complies with ISO 14064-1. The calculation covers the integrated process route of Aluminum production covering Bauxite Mining, Alumina Refining, Anode production, Smelting, Power Generation and Casting.The calculation covers the integrated process route of Aluminum production covering Bauxite Mining, Alumina Refining, Anode production, Smelting, Power Generation and Casting. Other contributions: Includes: Transport of raw material, Aluminum from alloying elements, cold metal and external scrap. The calculation of the carbon footprint does not include infrastructure and a few process inputs, which explains the discrepancy between the results reported in this EPD and Hydro s reported carbon footprint. The infrastructure accounts for 0.15 tons CO2-eq/ton Aluminium. All products are produced according to European standard EN 486. The products have a chemical composition within the alloy groups: 1000, 3000, 5000 and 6000.
