Association of Issuing Bodies (AIB)

The purpose of the AIB is to develop, use and promote a standardised system: the European Energy Certificate System - "EECS". EECS is based on structures and procedures which ensure the reliable operation of international certificate schemes. These schemes satisfy the criteria of objectivity, non-discrimination, transparency and costs effectiveness, in order to facilitate the international exchange of guarantees of origin.

In order to further facilitate this, the AIB operates an inter-registry communications Hub. Vision 2021-2025: The production, trade, distribution and consumption of energy can be electronically documented and tracked with energy attribute tracking certificates (EAT). The EECS® (European Energy Certificate System®) facilitates harmonised handling of EAT Systems, including guarantees of origin (GOs) issued under various EU Directives and other compatible national legislations.
