The perspectives and attitudes of the companies of the forest products industry operating in the fields of solid wood products, pulp, paper and paperboard products, engineered wood products and furniture manufacturing in Turkey on the chain of custody certification system and certified forest products were investigated. Within this scope, face-to-face interviews were conducted with the managers or owners of 177 companies. The data were obtained by using the questionnaire technique. The research methods included descriptive statistics, one-way analysis of variance and the Duncan test.
