This article analyzes the motivations, internalization challenges and outcomes of implementing certifiable standards for corporate biodiversity management. For this purpose, a qualitative study based on interviews with 39 environmental managers, auditors, consultants and other experts in the field was conducted. The findings show that the adoption of new standards for biodiversity management is essentially driven by the need to improve the social acceptability of activities that can have a significant impact on natural habitats. The possible benefits of certification, particularly in terms of stakeholder relationships, and the difficulty of measuring the intangible aspects of biodiversity issues are also discussed. The study contributes to the emerging literature on organizational biodiversity management and to the debates on the symbolic versus substantial adoption of certifiable environmental standards. Managerial implications for organizations interested in biodiversity management are also discussed. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
