This paper develops an inventory model for a closed-loop supply chain system (CLSC) involving of a manufacturer and retailer. A carbon tax policy is applied to cut down emission from production. transportation, and storage. To lessen the emissions, the manufacturer invests in green technologies. The manufacturer’s production process is assumed to be imperfect, so the lot deliveries to the retailer contain imperfect products. A mathematical model is proposed to minimize the joint total cost incurred by the supply chain. The objective of the model is to minimise total cost by determining the shipment size, number of deliveries, green investment, and safety factor. A numerical example and a sensitivity analysis are presented to show the application of the model and to investigate the influence of key parameters on the performance of the model.
