Carbon Footprinting in Supply Chains

This chapter presents an overview of the methods and challenges behind carbon footprinting at the supply chain level. We start by providing some information about the scientific background on climate change. This information is necessary to clarify the overall methodology behind carbon footprinting measurement. We also briefly review the main motivations for carbon footprinting. Then we propose an overview of the main methods available to measure a carbon footprint at the supply chain level. We propose to organize these methods in function of the quantity of information required, and we highlight a trade-off between the scope of measurement chosen and the accuracy of the estimation made. We continue by emphasizing the importance of supply chain (Scope 3) emissions in many supply chains. Finally, the chapter also discusses some challenges related to supply chain carbon footprinting. We specifically consider how to get information in practice, what level of accuracy is needed and how to extend the horizons beyond carbon.

Une méthode intégrée pour la gestion des chaînes logistiques durables

Nous proposons une méthode intégrée pour la planification des chaînes logistiques (CL) durables, structurée en trois phases. La première fait le lien entre la performance durable et les décisions de planification des opérations de la CL. La deuxième permet de rendre compte des caractéristiques du système de production mis en œuvre. Dans la troisième phase, la planification de la CL est optimisée en tenant compte de sa performance économique, environnementale et sociale. Pour mettre en avant la valeur pratique de notre méthode, nous l’avons appliquée à un problème de planification tactique. Nous avons obtenu plusieurs solutions de compromis présentant différents niveaux de performances économique, environnementale et sociale, permettant au décideur de choisir la solution qui correspond le mieux à sa stratégie.

An Integrated Approach for the Optimization of the Sustainable performance: a Wood Supply Chain

This paper proposes an integrated approach that embeds the economic, environmental and social performances in the planning activities of the supply chain (SC). The approach is applied on a realistic case study inspired by the lumber industry where divergent manufacturing processes and various cutting patterns are involved. We first identify the sustainability objectives to be measured. Then, we link these objectives to the SC decision planning. Next, we define performance measures to assess the achievement of each objective. This triptych-based approach is transposed to a multi-objective mathematical programming (MOP) that serves as a performance optimizing and assessing tool. The MOP models a tactical planning problem where the SC is represented as a network of activities. The problem is resolved using the weighted sum method.
