Measuring, reporting, and managing a company’s sustainability performance is starting to drive employee retention, corporate reputation, and contribute to business success. Chief Sustainability Officers (CSOs) will report environmental sustainability metrics for the entire enterprise. However, to track progress against the enterprise’s goals and determine where inefficiencies are and improvements can be made, CSOs will need each department or function in the organization to provide more granularity in their measurement of sustainability metrics. IT is one important department where there is much interest in understanding energy consumption and, ultimately, its greenhouse gas (GHG) emissions.
