<![CDATA[Storage of frozen tuna requires consistent cold-chain management to maintain product quality and food safety while addressing the high energy demand of cold-storage facilities. This condition highlights the importance of implementing the green warehouse concept to improve energy efficiency and reduce environmental impacts without compromising temperature control performance. This study aimed to identify processing stages of frozen tuna in cold storage and to identify implementation of green warehouse aspects in frozen tuna storage. Structured literature review was conducted by analyzing scientific publications related to frozen tuna processing, cold-chain management, green warehousing, and energy efficiency published primarily during 2017–2026. Results indicate that frozen tuna processing generally involves raw-material receiving and handling, mechanical processing, freezing, and frozen storage, with temperature control serving as a critical factor in maintaining product quality and food safety. Implementation of green warehouse principles in cold storage encompasses building and insulation efficiency, energy-utility management, efficient lighting, material handling and automation, material and packaging management, and operational optimization. Key strategies for frozen storage include optimizing warehouse filling levels, minimizing door-opening frequency and duration, scheduling defrost cycles, maintaining refrigeration systems, utilizing renewable energy, and implementing digital temperature monitoring technologies. Therefore, green warehouse implementation in frozen tuna storage should integrate quality preservation, energy efficiency, operational efficiency, and environmental impact reduction to improve the sustainability of the cold-chain system without compromising product quality. Key words: cold chain, cold storage, energy efficiency, frozen storage, frozen tuna, green warehouse]]>
