EECS GOs: Introduction

The EECS is maintained and managed by the 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 energy certificate schemes in Europe. 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.” Source: AIB
