"AIB - guaranteeing the origin of European energy"

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.

Our members

Members of AIB are drawn from energy certificate system administrators across Europe. All are competent bodies for guarantees of origin or their agents - mostly transmission system operators, electricity regulators and energy market operators.

See our scheme members, read about EECS or apply for membership.


The European Energy Certificate System (EECS) offers a framework for creating and transferring electronic documents (EECS Certificates). For each megawatt-hour of energy, EECS certifies the quality of its source and/or the method of its production.The EECS Rules ensure that EECS energy certificate systems are reliable, secure and inter-operable - these harmonised standards enable the owners of EECS Certificates to transfer them to other domestic and international account holders.

See the EECS Rules, and take a look at the CEN standard.
