Wholesale and retail operators of fuels, as well as consumers of fuels not supplied by wholesale or retail operators, are obliged to sell / consume a minimal quota of biofuels. The minimal amount is set at a general level (all biofuels) and at a specific level (minimal amount of biofuels in diesel and in gasoline). Each obligated subject has to present a number of certificates to the national certification entity to prove compliance. Certificates have a value of 1 toe. In case of non-compliance with the targets, a penalty fee applies. In case of over-compliance (some parties selling or consuming more than they are obliged to), the amounts collected from the penalty fees are redistributed by the certification entity proportionally to the subjects that sold / consumed biofuels exceeding their set quota obligation.
