See Chapter 15 for a description of corporate sustainability. The proposed approach provides us four unified efficiency measures related to natural disposability and/or managerial disposability. These unified efficiency measures serve as a computational basis for identifying a new type of scale efficiency measures, none of which has been discussed in previous chapters, including Chapter 18.

After theoretically discussing the proposed scale efficiency measures, this chapter applies the proposed approach to examine the level of corporate sustainability among petroleum firms in the United States. The petroleum firms are generally classified into two categories. One of the two categories includes a group of “integrated companies,” which have a large supply chain for spanning both upstream and downstream functions in the US petroleum industry. The other category includes “independent companies” that focus on the upstream function in their business operations.
