Under the EU ETS Registry Regulation 2216/2004/EC, each Member State establishes a national registry that links to the others and to the Community Independent Transaction Log (CITL). Each national registry connects to the backbone which in turn ensures a secure, compatible and smooth integration of all systems under one European umbrella. The sum of all registries together with the CITL operates as the Registries System.  Allowances are issued to registry accounts established for each affected facility.


EU Emissions Trading


Domestic or regional emissions trading schemes that use Kyoto units also undertake their settlement through these registry systems. For example, under the second phase of the European Union emissions trading scheme, EU allowances are specific Kyoto units which have been designated as being valid for trading under the scheme. Transactions in EU allowances are therefore recorded automatically as transactions under the Kyoto Protocol.

As EU trading legislation sets in place rules over and above those agreed for the Kyoto Protocol, a supplemental transaction log has been implemented by the European Commission. The Community Independent Transaction Log has been in place since the start of the scheme in 2005 and EU registries are now operating with it.

For the start of the Kyoto commitment period in 2008, EU registries are to switch their connections from the CITL to the ITL. The ITL will conduct “Kyoto checks” on transactions proposed by both EU and non-EU registries. In the case of transactions involving EU registries, the ITL will forward information to the CITL so that it can conduct “supplementary checks” defined under the EU scheme.
