Responsible fiber sourcing
All Stora Enso kraft pulp grades – bleached and unbleached – come from traceable sources and sustainably managed forests, available with FSC®*** and PEFC™ chain-of-custody certification. Full traceability from forest to fiber ensures our customers can produce certified, renewable and eco-labelled products with confidence.
In the Nordics, our production units use pine and spruce from privately owned forests where growth exceeds harvesting. Each harvested area is regenerated, securing the long-term availability of renewable raw material.
As a global sustainability leader, Stora Enso continues to set ambitious environmental and social targets, advancing a more circular bioeconomy.
