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.


FaStGO - Facilitating Standards for Guarantees of Origin

The FaStGO project provides expert advice to the European Commission DG ENER, based on the terms of Reference N° ENER/C1/2019-517: “Technical support for RES policy development & implementation. Establishing technical requirements and facilitating the standardisation process for guarantees of origin on basis of Dir (EU) 2018/2001.”

You are welcome to help upgrading the EN16325 standard on guarantees of origin for energy. See how on the FaStGO project sites.





Interested in joining AIB?

If you are an issuing body for GOs or voluntary certificates and wish to join, then read more here.See a generic presentation about AIB and GOs or

take a look at our Youtube channel, which contains videos about the AIB and guarantees of origin.
All these documents, presentations and information are developed by the AIB, its members and market parties.


AIB welcomes issuing bodies administering energy certificates for electricity, gas, hydrogen etc.

The AIB facilitates a forum for issuing bodies who administer a reliable system of internationally tradeable energy certificates. AIB now also facilitates independent decision making by gas issuing bodies on gas related aspects.

The European Energy Certificate System (EECS) provides a basic ruleset for energy certificates for all energy carriers and several purposes. The Electricity Scheme has been operational for almost two decades, the EECS Gas Scheme has been added in November 2019. The EECS Rules have also adopted rules that facilitate GO issuing following energy carrier conversion.

AIB operates a Hub for international trade of energy certificates, avoiding bilateral connections between registries. 600 TWh of electricity guarantees of origin were transferred internationally in 2019.

The EECS Gas GO Scheme fully facilitates guarantees of origin for gaseous energy carriers (including hydrogen) under article 19 of the Renewable Energy Directive 2018/2001, and their effective cross border transfer. It also facilitates voluntary data fields on the gas certificate, which can be used for other purposes (sustainability criteria, green house gas emission data, assessment reports certifying their value, etc). This is a building block towards also art. 25-31 of REDII certification and can be further developed.

AIB encourages and facilitates (aspiring) gas issuing bodies to join the EECS Gas Scheme Group and share experience, establish practice and further refine the rules.

The Open Market Committee (OMC) is an important meeting point where AIB and its members – the competent bodies for guarantees of origin across Europe – and market participants can develop a better understanding of each other’s needs and wishes.
