NOTE: 2007 version described. (improvements added in 2008 version)
The description below is for the 2007 version. After recent consultation a simplified version is now preferred based around fuel delivered and the bunker delivery notes (BDN). BDNs are already required by the MARPOL Annex VI. The 2007 description has however an advantage of allowing to fully implement an IMO CO2 index. Furthermore, the 2008 Autumn version differentiates between Annex I and non-Annex I destinations to deliver on the UNFCCC principle of common but differentiated responsibilities (CBDR).
Data collection. We propose that ship managers submit a fuel used record to the scheme database for the recent voyages once a month, along with the volume of work and distance travelled for all ships under their management.
Monitoring and reporting. For monitoring and subsequent reporting the emissions are calculated by the scheme based on amount of voyage fuel used and type of vessel/engine, using appropriate emission factors (tier 2 methodology as per IPCC, 2006 Guidelines for National Greenhouse Gas Inventories).
Verification. Accounting and verification for the central organization will be subject to ISO 14064 standard for greenhouse gas accounting and verification. Electronic verification of fuel reports might be augmented in certain cases with the ship log verification by an authorised official at any port participating in the scheme.
- It is proposed to enforce the compliance in selected ports for:
- Provision of relevant data for the most recent voyages;
- Payment of the emission charges for the period ending three months earlier (or similar).
