Environmental Impact and Sustainability

Industry practitioners and policy makers are under increasing pressure to continuously reduce the negative environmental impact of their supply chains. An original equipment manufacturer that is concerned with minimizing the environmental impact of its activities should choose its suppliers based on the trade-off between costs and respective emissions. This decision requires the manufacturer to coordinate closely with its suppliers in order to achieve the required level of emissions. In this paper, we develop a mixed integer program for the carbon-sensitive supply chain that minimizes emissions throughout the supply chain by taking into consideration green procurement also known as environmental sourcing. A sample case study is presented with a life cycle assessment of three scenarios based on different carbon emissions costs.
