Metsä Tissue will aim to have fossil free mill fleet by 2030 and accordingly it has stopped using coal as an energy source in its Kreuzau's mill in Germany. Since September 2023 the Kreuzau mill in Germany has been replacing the use of fossil-based lignite by wood pellets in the mills heat production.

Currently tissue paper production process creates annual emissions of 90,000 t CO₂ and by implementing wood pellets instead of lignite, fossil-based CO₂ emissions will be reduced by 60,000 t per year, meaning over 30 per cent reduction of CO₂ emissions yearly in Metsä Tissue. Through this change Metsä Tissue's Kreuzau mill compares favorably also with the EU Emissions Trading Scheme (ETS) benchmark as the emission level at Kreuzau mill will be 200 kg CO₂/t tissue paper compared to 340 kg CO₂/t tissue paper.

Metsä Tissue is one of the leading tissue paper suppliers in Europe to households and professionals and one of the leading greaseproof paper suppliers globally. Metsä Tissue is part of Metsä Group.
