The production, trade/distribution, and consumption of renewable energy can be electronically documented and tracked with Energy Attribute Certificates (EACs). With those certificates, companies can claim the environmental benefit of renewable energy production for their own electricity consumption. The Higg FEM 4.0 does not require you to purchase them, however, the assessment does ask if facilities have some for example. This guidance will allow you to read about specific questions and what needs to be done to answer them with a yes, please feel free to read more about how the FEM4.0 asks about EACs. If the guidance is not sufficient, please don't hesitate to reach out again.
