Seaport activities account for 3% of global carbon emissions, and as an important industrialised economic centre, ports engage in numerous industrial and financial activities that could increase their greenhouse gas (GHG) emissions and carbon footprints (CF). The 13th sustainable development goal (SDG) states that these activities must be balanced with environmental considerations. Therefore, as critical marine infrastructure, seaports need CF reduction initiatives. This scoping review covers important ideas and ways to reduce the CF in seaports to simplify future policymaking. These approaches include energy management systems, equipment and infrastructures, and carbon emission policies and laws specific to ports. Relevant literature is classified, evaluated, and discussed. The findings are interpreted and discussed based on the current state of ports around the world, using statistical data to demonstrate that there are sufficient regulations and standards in place, but that more work is needed to replace conventional systems with intelligent ones and fossil fuels with renewable energy. Finally, the scoping review results, and scientific interpretations, thoughts, proposals, and recommendations are presented as references for related studies in the future.
