All Guest Choice products are recognized through the Programme for Endorsement of Forest Certification (PEFC™) identifying the paper as coming from sustainably managed forests. The PEFC’s Chain of Custody certification is one of the most comprehensive and rigorous methods available for tracking wood products from forest to final production.* PEFC is a leading global alliance of national forest certification systems. As an international non-profit, nongovernmental organization, PEFC is dedicated to promoting sustainable forest management through independent third-party certification. PEFC works throughout the entire forest supply chain to promote good practice in the forest and to ensure that forest-based products are produced with respect for the highest ecological, social and ethical standards. In addition, this standard includes management requirements, including health, safety and labor issues.
