  1. Shipping, CO2 and other Air Emissions T.J. Gunner

  2. INTERTANKO Assessmentof World Bunker Consumption • The assessment undertaken for the IMO Secretary General’s Expert Group • The assessment is a “bottom up” review • Covers all ships requiring certification for Annex VI – 400 gt and above • Relies upon data from Lloyds/Fairplay Database and ship owners and operators

  3. Ship Numbers and Sizes

  4. Ships and theirengine sizes

  5. Ships and their Total Bunker Consumption

  6. Ships and their Bunker Consumption by type

  7. Ships and their CO2 Emissions

  8. Ships and their SOx and NOx Emissions

  9. CO2 Emission reduction methods for Ships • Reduction of excess Fuel consumption by utilisation of waste heat and reduction of losses – INTERTANKO proposal in WGAP 1/2/5 - • Use of MDO as fuel – Saving 31.5 million tonnes • Reducing Sulphur content of fuel – less “buffering” and release of CO2 from the Oceans – potential saving 27 million tonnes • Project to recover CO2 by tankers with zero “footprint” – potential saving 1.5 million tonnes.
