Some suppliers sell renewable energy under an independent criteria scheme or label, which further defines the supplied energy according to (e.g.) the type of technology, date of commissioning of the plant, receipt of public support etc.

The use of transferable certificates makes these schemes much simpler and more efficient, as renewable energy production has already been verified and audited.

The information on the certificates can be used to confirm that source of the energy is what the supplier has promised. Also, an organisation which is independent of the supplier (perhaps a label operator) can confirm that the types and quantity of certificates cancelled reflect the suppliers promises.

Independent Certification Schemes (ICS) are not certificates in themselves: ICSs categorise certain types of energy sources (i.e. fuels) or supplier products under a specific sustainability scheme according to a set of agreed criteria; and an indication of such can be placed on each qualifying certificate.  These ICSs have been defined and governed by organisations independent of suppliers.

(See also Fuel Mix Disclosure.)

Article 17 of the RES Directive (2009/28/EC) requires biofuels and bioliquids to be distinguished according to whether or not they fulfil particular sustainability criteria. However, article 17 does not link Guarantees of Origin to sustainability criteria: a GO that does not satisfy such criteria can still be issued. The Directive allows factual information on aspects of sustainability to be added to a GO (article 15(6) says "...must specify at least..."), although it does not explicitly require GOs to record the sustainability of the energy source. Hence EECS supports the differentiation of GO according to sustainability criteria.

Besides the legal requirements for sustainability arising from the RES Directive, further sustainability schemes - particularly those which apply to biomass fuels (e.g. the Forest Stewardship Council (FSC)) - are of market relevance.

Requirements imposed by other stakeholders
There are other  reasons why it is useful to differentiate GO according to sustainability criteria:

  • Market participants would like GO to identify eligibility for green power labels. This reliable, convenient way of satisfying environmental claims might lead to more diversified product portfolios
  • The E-TRACK II project has recommended that GO-like tracking instruments be replaced by GO, which should also record compliance with the additional criteria applied by these other tracking instruments
  • In some Domains, such information is already contained in EECS.

Role of the AIB

The EECS Rules are being adjusted to support regulations for governance and verification of ICSs, identification of eligible plant and energies, and the technical changes to the registries etc.

The core expertise of AIB members is tracking of information, and criteria and production-related verification should be assured by such qualified and authorised institutions.

The sustainability criteria proposed by the Directive should be implemented by the EU (or its member states) respectively. Voluntary quality labeling schemes and certificate types have usually procedures in place for verifying the respective criteria.

Such information is administered by EECS according to the requirements of the respective verification process imposed by the governance rules of the sustainability, certificate or labeling scheme. EECS certificates include verified information on whether the respective electricity volumes qualify for the scheme, and this information is transferred with the certificates.


  • EECS certificates record whether the respective electricity qualifies for a particular ICS
  • An ICS wishing to be recognised under EECS should apply to the AIB, with the support of a current member, stating the procedure for verification of compliance with the ICS
  • Members of AIB need not issue certificates under an ICS or display ICS-related information, but must retain ICS-related information for imported certificates in their registry and transfer this with related EECS certificates
  • Responsibility for verifying compliance with ICS criteria lies with the ICS operator.
