What is the Union database (UDB)?

The Union Database (UDB) is a database pursuant to Article 28(2) and (4) of Directive (EU) 2018/2001 (RED II). It is used for the traceability of gaseous and liquid fuels. The aim of the UDB is to avoid double counting and to minimise the risk of irregularities and fraud. The UDB records sustainability certificates for biofuels and the corresponding raw materials.

Legal basis of the Union Biofuels Database (UDB):

Article 28 (2) of Directive (EU) 2018/2001, the so-called RED II, provides for the introduction of a uniform and binding database at European level, in which all sustainability certificates for biofuels in the transport sector and the corresponding raw materials are recorded. In detail, this means:

'2. The Commission shall ensure that a Union database is set up to enable the traceability of liquid and gaseous fuels for transport that may be counted against the meter referred to in Article 27(1)(b) or taken into account for the purposes of the first subparagraph of Article 29(1). Member States shall require the economic operators concerned to provide information in this database on the transactions carried out and the sustainability characteristics of those fuels, including their life-cycle greenhouse gas emissions, from the place of production to the fuel supplier placing them on the market. Member States may set up a national database linked to the Union database, ensuring that data entered are immediately transferred between databases. The information necessary to verify compliance with the requirements referred to in the first and fourth subparagraphs of Article 25(1) shall be entered by fuel suppliers in the relevant database.'
