Abstract: Supply chain activities significantly contribute to ecological deterioration due to carbon emission. Mainly its purpose is to integrate environmental issues as energy efficiency and carbon emission. The paper develops three-echelon sustainable supply chain of deteriorating products with deterministic demand rate under energy and carbon emission cost. This work minimises the total integrated cost and optimises critical time. The supply chain system with carbon emission under inflation provides a better result for environmental concern. Some theoretical work is done to enunciate the objective function using the classical optimisation techniques. The decision-makers may reduce integrated costs by considering the effect of inflation. To exemplify and validate the proposed study, numerical analysis is done. Further, sensitivity analysis is presented to study the effect of inventory parameters on inventory decisions. The total integrated cost with carbon emissions is highest compared to without carbon emissions.
