  1. GHG Indexing of Shipsand its updates Dr. Tim Gunner, Technical Consultant, Intertanko

  2. IMOPositionAssembly Resolution 963 • “To identify and develop the mechanism or mechanisms needed to achieve the limitation or reduction of GHG emissions…. and to give priority to: • The establishment of a GHG Baseline • The development of a methodology to describe the GHG efficiency of a ship… recognize that CO2 is the main GHG emitted by ships • The development of guidelines by which GHG emission indexing may be applied in practice • The evaluation of technical, operational and market based solutions

  3. IMOPositionand Findings • IMO Study on Greenhouse Gas Emissions from Ships published in June 2000 Findings: • Ships contribute about 1.8% of World’s total CO2 emissions • Reductions feasible through technical and operational measures

  4. IMO ProcedureMEPC/Circ.471 • Interim Guidelines for Voluntary CO2 Indexing for use in Trials – issued 29 July 2005 • Trial period until MEPC 58 – October 2008 – where report of experiences requested

  5. The CO2 Index EquationIMO Guidelines

  6. Specified CCarbon Factors IMO Guidelines

  7. Example Data

  8. Example Calculation

  9. GHG Indexing of Ships • CO2 Equation used for “Yearly” Calculations C. Con. Factor * S FCi / S (M Cargoi * Dist i ) • CO2 Equation used for “Voyage” Calculations C. Con. Factor * FCi / (M Cargoi * Dist i )

  10. GHG Indexing of Ships • GHG Index used for “Yearly” and “Voyage” calculations uses same principle but incorporates refrigerant gas refill tonnage (RF) and the Global Warming Potential (GWP = 3780) of the gas to equate it to CO2 equivalency (C.Conv.Factor * S FC i) + (S RF i * GWP) / S(M Cargo i * Dist i )

  11. INTERTANKOCO2 and GHG Spreadsheet

  12. INTERTANKOAdd. to Spreadsheet (Sulphur)

  13. INTERTANKOAdd. to Spreadsheet (NMVOC)

  14. A Review of Data collection so far

  15. GHG Indexing of ShipsExample of a VLCC (1) Voyage Data Calculation

  16. GHG Indexing of ShipsExample of a VLCC (2) Voyage Data Calculation

  17. GHG Indexing of ShipsExample of VLCCs Voyage Data Calculations

  18. CO2 & GHG Indexing of ShipsExample of Chemical Tanker Voyage Data Calculation

  19. Comparative Values and Economies of Scale But one has to take into account others’ views 1 ship emission = 350,000 cars emissions

  20. Any Questions orOffers of Help for Data Collection
