This study designed an integrated certification system of ISO 50001 (energy management system) and ISO 14001 (environmental management system) with the goal of reducing corporate carbon emissions, and analyzed cases of applying it to actual management. In order to overcome the limitations of individual certification, an integrated operating system of the two standards was established, and a method was sought to maximize corporate energy efficiency and carbon emission management performance. After introducing the integrated system, the company under study reduced energy consumption by up to 30%, and carbon emissions were also significantly reduced. These results were achieved through internal process improvement and supply chain collaboration. This study suggests that the ISO integrated certification system can contribute to cost reduction and sustainable management, and proposes an implementation model that can be utilized in various industries in the future.

As modern weapon systems become increasingly complex, the need for integrated management of component standardization and airworthiness certification has grown significantly. This study proposes a system-based approach to establish an integrated management framework that addresses inefficiencies, certification delays, and supply chain risks inherent in current military aircraft development processes. The research reviews the functional scope of component standardization and compares airworthiness certification systems across domestic and international defense sectors. It identifies limitations caused by the fragmented management of parts and certification processes, and proposes a digital platform that interconnects parts databases, configuration control, quality assurance, and certification modules. The framework incorporates AI and digital twin technologies to monitor and manage reliability across the entire life cycle of a weapon system. This study lays the foundation for enhancing the operational efficiency of national defense technologies, and contributes to strengthening the autonomy and global competitiveness of the Korean defense industry.
