Supply chain sustainability, which includes designing green supply chains, will gain much more attention in the future. Indeed, most companies are still in the early stage of considering a green initiative. Traditionally, optimization models for supply chain network design looked to different strategic network alternatives, and analyze the trade-offs between logistics costs and service requirements. Today, with the strong emphasis in reducing greenhouse gas footprint, the integration of such consideration into the supply chain network design phase will provide to companies much more visibility on how to manage efficient, effective, and green supply chains.

While the social dimension is sometime harder to capture or quantify in mathematical terms, the Emission Trading Schema (ETS) introduces a natural trade-off between the economic and the environmental dimensions. This article addresses the design of supply chains that are also sensitive to the carbon market. Carbon emissions and total logistics costs are integrated in the design of the supply chain using a multi-objective mixed-integer linear programming model that is solved by goal programming. The proposed methodology provides decision makers with the ability to evaluate the trade-offs between total logistics costs and carbon offsetting under different supply chain operating strategies, environmental regulatory constraints and carbon market evolution. The approach is presented through an illustrative example derived from the steel industry where new legislation imposes regulatory carbon caps on emissions. The results show that this approach is a good starting point for a more comprehensive framework for sustainable supply chain network design.

Through a stochastic inventory model, our research extends the traditional minimization cost problem by incorporating environmental legislation. We consider a finite-horizon closed-loop system whereby decisions are subject to an emissions trading scheme and to random demand and returns. Demand can be satisfied by two sources. The primary source is environmentally friendly but expensive, whereas the second is cost effective but with negative environmental consequences. The problem is formulated as a stochastic dynamic problem, where replenishment and carbon management decisions must be made at each period. The objective is to describe how replenishment and carbon management strategies are affected by environmental constraints. In particular, considering the computation restriction of dynamic programming, in order to extend the results, we propose a genetic algorithm to find near-optimal solutions for larger instances. A sensitivity analysis is performed to identify the impact of carbon allowance prices, emission-cap and other environmental factors in the decision-making process. The results indicate that environmental strategies and their factors have an impact on replenishment decisions. There is an emission-cap from which a company must focus on decisions at the strategic level rather than on tactical and operational decisions. In addition, if the carbon allowance price is such that the environmental benefit absorbs the cost of less polluting technology, a change in the inventory policy must be made.

This paper introduces a mixed-integer linear programming based framework for sustainable supply chain design that considers life cycle assessment (LCA) principles in addition to the traditional material balance constraints at each node in the supply chain. Indeed, the framework distinguishes between solid and liquid wastes, as well as gaseous emissions due to various production processes and transportation. The framework is used to evaluate the tradeoffs between economic and environmental objectives under various cost and operating strategies for an aluminum company. The results suggest that current legislation and Emission Trading Schemes (ETS) must be strengthened and harmonized at the global level in order to drive a meaningful environmental strategy.
