 Energy efficiency is essential for economic and social development as it provides numerous benefits to various stakeholders, including cost savings, improve competitiveness, profitability, and quality.

Supply chain management offers a promising approach to addressing these challenges as it allows for the integration of energy efficiency into existing operations. This paper reviews the literature on energy efficiency in supply chains and identifies potential research streams to further advance the field.
