Guaranteeing the origin of European energy


AIB - "guaranteeing the origin of European energy"

The purpose of the AIB is to develop, use and promote a standardised system of energy certification for all energy carriers: 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.

AIB’s members are the competent bodies for the administration of Guarantee of Origin schemes in 25 countries ( EU, EEA and Energy Community member states). Three more countries are likely to join by the end of 2020.

In 2019, 707 million certificates (707 TWh) were issued, while 613 million were transferred internationally and 613 million were used and cancelled. The market for electricity GOs continues to grow at about 10% per year.

The AIB also provides a knowledge centre for energy certificate authorities across Europe, providing and sharing advice and guidance.
