ABSTRACT: Sustainability is essential for growing environmental concern especially those related to carbon emissions by the supply chain, and production. In today’s era, mitigating carbon emissions, and waste has become a major concern for a manufacturing firm or industry. Different tax policies are employed for high-emission industrial, and commercial activities. This study proposes a sustainable inventory system for decaying products that are socially, economically, and environmentally savvy. It is assumed that the demand is advertisement, price, and time-sensitive. The price and advertisement of a product attract the customers to buy more or less. Most of the products have a fixed life span or expiration date for maintaining their quality in original properties. Therefore, the customers prefer the products of maximum life span. This model is designed with a sustainable goal that the incurred total cost is minimized over a planning horizon, together with the determination of optimal price, time period of positive inventory, and the cycle length. The practical utility, and a better understanding of this model are shown with the help of a numerical example. A sensitivity analysis of some crucial parameters is conducted, and it is based on their variations.
