Due to the increasing focus on green consumerism, sustainability disclosure—company informing its stakeholders of its involvement in sustainability—is an integral part of stakeholder management. Nevertheless, the sustainability reports published by container shipping companies exhibit unique structures and content. Existing sustainability disclosure frameworks are generic and do not cater to B2B industries, such as container shipping. Moreover, limited studies have been conducted to explore the sustainability disclosure framework of the container shipping industry. With a hierarchical unsupervised text-mining method, the latent information of major listed container shipping companies' sustainability reports has been explored. A unified framework is produced comprising three primary dimensions: employee training and management, sustainable business management, and sustainable shipping operation. Each primary dimension has three secondary sub-dimensions. Theoretically, this research uncovers themes and patterns on how container shipping companies disclose sustainability. Managerially, this research guides container shipping companies on preparing and organizing sustainability disclosure. For regulators, policymakers, and global investors, this research also provides implications on evaluating container shipping companies’ sustainability performance and serves as a benchmark against broader sustainability goals such as sustainable development goals (SDGs).

由于对绿色消费主义的日益关注，可持续性披露——公司告知其利益相关者其参与可持续性——是利益相关者管理的一个组成部分。尽管如此，集装箱航运公司发布的可持续发展报告展现了独特的结构和内容。现有的可持续性披露框架是通用的，不适合 B2B 行业，例如集装箱运输。此外，还进行了有限的研究来探索集装箱航运业的可持续性披露框架。采用分层无监督文本挖掘方法，挖掘主要上市集装箱航运公司可持续发展报告的潜在信息。产生了一个统一的框架，包括三个主要维度：员工培训和管理，可持续的业务管理和可持续的航运运营。每个主要维度都有三个次要子维度。从理论上讲，这项研究揭示了集装箱航运公司如何披露可持续性的主题和模式。在管理上，这项研究指导集装箱航运公司准备和组织可持续性披露。对于监管机构、政策制定者和全球投资者，这项研究还对评估集装箱航运公司的可持续发展绩效提供了启示，并作为衡量可持续发展目标 (SDG) 等更广泛可持续发展目标的基准。这项研究揭示了集装箱航运公司如何披露可持续性的主题和模式。在管理上，这项研究指导集装箱航运公司准备和组织可持续性披露。对于监管机构、政策制定者和全球投资者，这项研究还对评估集装箱航运公司的可持续发展绩效提供了启示，并作为衡量可持续发展目标 (SDG) 等更广泛可持续发展目标的基准。这项研究揭示了集装箱航运公司如何披露可持续性的主题和模式。在管理上，这项研究指导集装箱航运公司准备和组织可持续性披露。对于监管机构、政策制定者和全球投资者，这项研究还对评估集装箱航运公司的可持续发展绩效提供了启示，并作为衡量可持续发展目标 (SDG) 等更广泛可持续发展目标的基准。
