Carbon footprint reports

Having clear sustainability information on product level enables Gränges’ customers and other stakeholders to understand, evaluate, and compare Gränges’ products from a sustainability perspective. The company can offer customers third-party verified carbon footprint certificates and a detailed carbon footprint report outlining the methodology. During 2023, Gränges expanded the use of its internal life-cycle and carbon footprint assessment tool which is now used in all Gränges’ production facilities. This means that the company has reached its 2025 target of 100 percent of Gränges’ products to have third-party verified sustainability information available.

The model covers the carbon footprint impact from bauxite mining to inbound transports and Gränges’ own activities up until delivery from the site and can be applied on the full product portfolio in Gränges’ operations. To ensure transparency and credibility, Gränges has engaged the external party IVL Swedish Environmental Research Institute to verify the methodology, process and routines used in the assessment. The carbon footprint assessments have been conducted in accordance with ISO 14040, ISO 14044 and ISO 14067.
