This article aims to understand why extractive firms in the industrial logging industry in central Africa are reluctant to certify or label their activities. The methodology is based on three empirical case studies of logging companies in Cameroon: one opposed to certification and labeling (the model), the other is in the process of being certified (intermediate case) and the last is certified (negative case). The preferred option followed by this study was to avoid the copying of the first case by prospecting an intermediate case. The "negative" case permitted the model to be saturated. The comparative analysis of data collected highlighted some key obstacles to the commitment to environmental labeling: corruption, low turnover, high certification cost and the source of capital.
