The maker of Velvet toilet tissue has warned that its UK workforce could bear the brunt of a restructuring set to cost 3,600 jobs.
Svenska Cellulosa employs about 7,000 staff at 30 sites across the UK, including Edinburgh, London, Northampton, Darlington and Portsmouth.
The company said the UK, Denmark, Sweden and The Netherlands would be hardest hit.
The move, which affects 7% of the group's global workforce, is part of a major drive to reduce costs after it was hit by tough market conditions and overcapacity.
It follows another cost-saving programme implemented in 2004 that led to 1,200 job cuts.
A spokesman said the group could not say how many jobs would go in the UK, but that it was negotiating with unions.
