Benchmarking the environmental performance of supply chains through eco-intensity

The majority of the environmental impacts in a typical supply chain arises beyond the focal firm, thus the need to quantify the environmental performance of extended supply chain. This work aims to introduce a quantitative approach to assess the eco-intensity of products considering the extended supply chain by adopting a decentralized recursive mechanism. The model is validated through a numerical example of a fictitious supply chain adopting secondary data. Products are benchmarked on the basis of their CO2 emissions and water consumption eco-intensity, allowing more informed and sustainable purchasing decisions by customers.
