To secure cargoes, containerships operate double or triple calling of ports in the Pearl River Delta (PRD) region in China. Such shipping operations generate high CO2 emissions. This paper suggest a green shipping network (GSN) as a useful tool to transship containers from feeder ports to hub ports to lower the overall CO2 emissions in the region. From the perspective of scale operations from using the hub-and-spoke approach and the deployment of mega ships, developing a GSN within the PRD region can be beneficial, both economically and environmentally, to port users in the container transport chain
