The implementation and use of environmental management systems (EMSs) depend on the perceived credibility of their certificates. This study aims to identify and describe factors influencing the importance of certification credibility of EMSs. This study discusses the significance of such systems to enterprise credibility by administering and analysing focus group interviews with 20 representatives from the production industry, education sector, certification bodies, and non-profit associations for environmental protection. The paper concludes that credibility of EMSs' certification depends on the certifying companies, and poor-quality audits facilitate the possession of certification as well as the universality of using certified systems. The positive reception of certified EMSs in companies induces the widespread use of certificates, fashion, and credibility, which can be increased by publication of audit reports. These conclusions emphasise the importance of strict auditing and control systems for certifications.

经认证的环境管理体系的可信度：焦点小组访谈的结果

环境管理系统 (EMS) 的实施和使用取决于其证书的可信度。本研究旨在识别和描述影响 EMS 认证可信度重要性的因素。本研究通过管理和分析对来自生产行业、教育部门、认证机构和非营利环境保护协会的 20 名代表的焦点小组访谈，讨论了此类系统对企业信誉的重要性。论文得出结论，EMS 认证的可信度取决于认证公司，而低质量的审核有利于获得认证以及使用认证体系的普遍性。企业对经认证的 EMS 的积极接受促使证书、时尚、和可信度，可以通过发布审计报告来提高。这些结论强调了严格的认证审核和控制系统的重要性。
