Energy Efficiency Measures on Cold Supply Chains Problem identification and gaps for the fish sector

In this paper, a literature review on studies addressed to understand the environmental impacts caused by the fish supply chains and potential energy efficiency measured in Europe is performed. A general definition of the cold chain is provided along with its main topicalities, such as quality degradation, food losses, social and environmental issues. The local fishery sector relevance is described for Latvia and then a bibliographic analysis is performed using a specialized tool that allows recognizing the main topics covered in the last years within the scientific community. Results show a lack of studies focuses on recognizing the benefits or setbacks of implementing energy efficiency measures in actors across the supply chain.
