The Association of Issuing Bodies – the AIB  – promotes the use of a standardized system, based on harmonized environment, structures and procedures in order to ensure the reliable operation of international energy certificatesystems. The standardized system is known as EECS – the European Energy Certificate System – and is set out in “ The EECS Rules “  and its supporting documents.
Of the 28 countries of the European Union , 18 are now active members, along with Norway and Switzerland. Since 2001, more than three billion (3,232 million) 1 MWh certificates have been issued, of which 2,859 million have already been used ( canceled ) to guarantee to consumers. In 2016, more than 531 million certificates were issued, and 387 million of these were canceled.
The work of the AIB is of relevance to all electricity customers, as the Guarantee of Origin (EECS) is a cornerstone of providing reliable disclosure to consumers.
