Maritime ports play a crucial role in the development of domestic and international trade and economies. Although near-port communities profit from economic benefits, there exist significant concerns regarding exposure to air emissions, which affect human health and climate change. To tackle this issue, a port authority can develop emission reduction plans and projects, whose performance is tracked through an air emissions inventory (EI). Despite the attention on EI methodologies in the past, little research has focused on the implementation of methodologies in information systems. Therefore, a case study is conducted in this paper to investigate the motivation for creating EIs and the obstacles in the EI-creation process from an information systems perspective. The results indicate that data confidentiality and weak information systems are major obstacles, which hinder the creation of high-quality EIs and generate additional costs. Our findings enable port stakeholders and decision makers to understand the current obstacles and facilitate the development of adequate information systems that support the creation of high-quality EIs.

海上港口在国内和国际贸易与经济发展中起着至关重要的作用。尽管近港社区从经济利益中获利，但人们仍然担心空气排放会影响人类健康和气候变化。为了解决这个问题，港口当局可以制定减排计划和项目，并通过空气排放清单（EI）跟踪其绩效。尽管过去对EI方法论给予了关注，但是很少有研究集中在信息系统中方法论的实现上。因此，本文进行了一个案例研究，从信息系统的角度研究了创建EI的动机以及EI创建过程中的障碍。结果表明，数据机密性和薄弱的信息系统是主要障碍，阻碍了高质量EI的创建并产生了额外成本。我们的发现使港口的利益相关者和决策者能够了解当前的障碍，并促进开发支持创建高质量EI的适当信息系统。
