Risk of sourcing from Ancient & Endangered forests

Actively engaging suppliers – no known high risk

Tangshan Sanyou was the first producer to have completed and released the results of their second CanopyStyle audit, in September 2020. The audit confirms that Sanyou had taken immediate action to remove all known high risks in their supply chain. Through their policy implementation and audit process, the company has taken meaningful actions to improve transparency and to help fill information gaps, when incomplete raw materials sourcing information was provided by some of their dissolving pulp suppliers.

While the audit did not fully confirm low risk, the company is engaging its supply chain partners to gather sourcing information to assess, and is actively working to address sourcing risks including requiring suppliers to attain Forest Stewardship Council (FSC) certification and implement science-based conservation planning of Ancient and Endangered Forests through supply contracts.

Key Improvements Required

  • Accelerate the of use of Next Generation Fibre Solutions in order to meet or exceed the aspirational targets outlined in the Vision: 20% by 2021, and 50% by 2030.
  • Continue to engage dissolving pulp suppliers, with Canopy’s support, to confirm low risk and/or risk mitigation measures and work towards elimination of all risk.
  • Prioritize the integration and sourcing of Next Generation Solution technologies and feedstocks for future expansion plans and new suppliers. At a minimum, continue to use ForestMapper and complementary guidance documents such as the advice note of Ancient and Endangered Forests and the Dissolving Pulp Classification to ensure no sourcing from Ancient and Endangered Forests.
  • Where virgin fibres are used, and they are not coming from key priority Ancient and Endangered Forests, procure higher volumes of FSC 100% certified inputs from sources that have achieved FSC Forest Management certification on the ground.

Areas where the company is showing leadership

Sanyou has shown continuous leadership over the last number of years, as they have:

  • Successfully trialed, and begun commercial production of initial volumes of viscose staple fibre made from 50% post-consumer recycled cotton textiles, supplied by Swedish company Re:newcell.
  • Deeply engaged with dissolving pulp suppliers in gathering sourcing information and engaged supply chain partners to participate in large-scale conservation solutions such as in Canada’s Boreal Forest.
  • Signed on to the Next Generation Vision for Viscose.
Introduced ReVisco, a viscose staple fibre made from 50% post-consumer recycled content dissolving pulp supplied by re:newcell. ReVisco was launched into the marketplace in 2020.
