What are some metrics that can be used to measure sustainability for a supply chain?

There are many metrics-both quantitative and qualitative-that can be used to measure sustainability in a supply chain.Some measures mentioned in the chapter include energy consumption,water consumption,greenhouse gas emission,and waste generation.It is important that these metrics be tracked across as wide a scope of the supply chain as possible.One measure discussed at length was that of landfill inventory.A qualitative measure of landfills would be the amount of undesirable odor created by the landfill inventory.A following quantitative measure is the loss of value for potential production or residential development due to the inherent odors.
