  1. Summary of UNFCCC / IMO Meeting April 2004 Nicola Lettington Department for Environment, Food and Rural Affairs. UK

  2. Purpose of the meeting Consider methodological issues relating to the estimation and reporting of GHG data from shipping under the UNFCCC. Provide advice to the IPCC on possible improvements of the methodologies for shipping to be included in the 2006 IPCC guidelines

  3. International / domestic reporting definitions Various interpretations of the terms ‘domestic’ and ‘international’ among parties contribute to inconsistency in reporting. Some present said that the differentiation is impossible to apply. Domestic and international segments of journeys are misrepresented in inventories.

  4. Main problems identified Differentiation between fuel used on domestic and international segments Tax and custom duties incentivise purchase of international bunkers for use in domestic trade Distinguishing fuel used in fishing and naval shipping

  5. Recommendations proposed for 2006 guidelines • Scope for improving IPCC definitions of domestic and international emissions. Difficult to obtain information about stops in same country. • Additional guidance about the estimation of emissions from fishing activities, military naval operations and non-commercial ships.

  6. Identification of possible alternatives for estimating emissions • Agreement that current IPCC methodology provides reasonable estimates based on fuel consumption. • Relationship between fuel consumed to CO2 emitted is considered fairly certain due to limited range of carbon contents in fuels (85 - 87.5%) • Generating an emission profile for individual ship voyages would be expensive and complex.

  7. Identify new/ updated emissions factors • Emissions factors for GHG emissions are based on the engine manufacturers rated output. • In most cases, these emissions factors do not reflect the consumption of fuel during the operation of ships. • Agreed there is scope to improve the emissions factors in existing guidelines.

  8. New procedures for activity data collection • Annex VI of MARPOL 73/ 78 requires a bunker receipt registry for all delivered bunkers to be maintained by suppliers. • Expected to enter into force next year. Will give accurate bunker sales data for national collation and an indication of national / international split. • Recommended that IPCC should consider the scope for the use of this information in the preparation of inventories.

  9. Next Steps • Recommendations agreed during the IMO / UNFCCC meeting will be included in UNFCCC Secretariat paper to be discussed at SBSTA20 in June. • Will form input into the IPCC meeting in September to consider the methodologies for estimating emissions from shipping.
