Managing Energy Productivity with a Sustainable Energy Index (ENDX)

ABSTRACT Business managers have few tools with which to determine whether their firm's energy productivity is getting better or worse. We propose a sustainable energy index (ENDX) that • tracks the energy productivity of a business • characterizes the description of energy risk on business operations • supports the continuous improvement of energy productivity • disassociates energy investments from cognitive bias A positive change of this index means that a business is improving its relative cost position and reducing its energy risk. A negative trend implies the opposite.
