Certification
Third-party certification has become an important instrument for ensuring and documenting that environmental work is pursued in line with the principles of sustainable development.
Norske Skog was an early adopter of certified environmental management systems, and has worked systematically with this since 1996.
In the summer of 1996, Norske Skog Skogn and Norske Skog Bruck were among the first mills in the world certified to the ISO 14001 environmental management standard.
In addition to environmental management systems, below are forest certification and Chain of Custody certificates for wood procurement and business units.
