Role and Status International Transaction Log

The function of the International Transaction Log (ITL) is to verify transactions proposed by registries to ensure they are consistent with the rules agreed under the Kyoto Protocol. Each registry sends transaction proposals to the ITL, which checks each proposal and returns to the registry its approval or rejection. Once approved, registries complete the transaction. In the event that a transaction is rejected, the ITL sends a code indicating which ITL check has failed and the registry terminates the transaction.

Each registry is to be connected to the ITL through secure communication channels established across the Internet. These connections will allow a registry to receive an immediate response from the ITL, typically within a matter of seconds after sending the transaction information.
The administrator of the ITL is the UNFCCC secretariat. A service desk, based in the United Kingdom, has been put in place to support the administrators of the ITL, registries and the CITL.
The ITL became operational with the CDM Registry and the Japanese Registry, in November 2007. All previous issuances of CERs in the CDM Registry have been confirmed by the ITL as having been in accordance with the Kyoto rules and the first CERs were forwarded to the Japanese Registry. The registries of Switzerland and New Zealand have followed.
The go-live of European registries with the ITL, originally planned for mid-November 2007, has been postponed. The UNFCCC secretariat is informed that these registries are to join the ITL simultaneously, together with the EU’s transaction log (CITL) under its trading scheme. At present, delays in connecting the CITL to the ITL mean that it has not been possible to fully test the two systems together. The timing of when European registries and the CITL will be able to commence operations with the ITL depends on the readiness of the CITL. We have no information available when this is scheduled.
Almost all Parties have completed the initialisation of their registry connections with the ITL. This process verifies that they meet all technical requirements prior to commencing live operations with the ITL. As far as we are informed (UNFCCC website), only 1 European registry (Bulgaria) and 1 non-European registry (Canada) have yet to complete their technical testing (several more are in the process of completing their procedural documentation).
