Shipping and the environment • ~60,000 ships (above 400 GT) • 7,507,000,000 ts goods / year • average distance 4,400 miles • >90% of total world trade • Consumes 9% of world oil • CO2 emission share < 1/2 oil consumption shareSimple infrastructure • Economics of scale: One VLCC = 8,000 tank trucks • 1 ltr of fuel on a modern Very Large Crude Carrier moves 1 tonne of cargo > 2,800 km but

Shipping and the environment • Fuelled by the dirtiest part of the barrel • resulting in emission of: • SOx • NOx • uncombusted hydrocarbon • Heavy metals • Soot
Reducing harmful emissions from ships • Onboard abatement technology • Scrubbers, filters, separators, catalysts • SECAs/NECAs • Sulphur/Nitrogen Emission Control Areas • Type and quality of fuel • Heavy fuel oil = a blending of refinery residues and distillate (up to 30% dist.) • Distillates = gasoil and diesel

Refineries are moving away from HFO • The new line at Neste’s Porvoo refinery will use residue oil to produce 1 m ts per year sulphur-free, clean motor fuels, particularly diesel fuel. • The fuel will meet the latest environmental requirements in Europe and N America. The refinery will be capable of considerably increasing the refining of very profitable products, such as sulphur-free diesel fuel.
Refineries are moving away from HFO • ……..company’s early commitment in the mid-1990s to making cleaner fuels, and by being proactive about finding the technology needed to achieve this.
Refineries are moving away from HFO • Residue upgrading benefits both the refinery and the community: • “Enhance financial performance • Eliminate high sulphur fuel projects • Replace obsolete utility faculties • Meet future product specifications • Reduce total refinery emission • Provide cost-effective H2 production based on converting residue • Produce power for refinery use and export • Increase feedstock flexibility – chance to use low-cost crude oils. • Secure or even expand and business opportunities” Enhance financial performance reduceemission more business opportunities Source: http://www.shell.com/home/content/globalsolutions-en/knowledge_centre/pres_speeches_papers/2006/refinery_residuals_010206.html Dr. Joachim Wolff: license and service manager for liquid and gas gasification for Shell Global Solutions.

Shipping needs INTERTANKO seeks • Significant reduction of harmful emission • Long-term, predictable and solid IMO standards • A feasible, realistic and sustainable solution • No unilateral nor regional regulations
Why not scrubbers? • Still under testing (2 ship limited scale) • Large • Expensive • Difficult (impossible?) to install • CO2 emission (buffering effect) • Leaves hazardous waste • Waste disposal – no-one wants it • Tonnes of seawater need to be processed/added We are involved in transportation – not waste treatment
Why not SECAs? • Air pollution knows no borders • Most ships operate close to shore • International shipping needs global regulations • Switching fuels – a safety problem • More SECAs on the way- and more problems • LSFO availability • “ ..refineries have a clear incentive for further conversion of its entire residual streams to distillate products compared to residue desulphurisation to produce more LSFO” (CONCAWE) Nov 2007 May 2006 SECAS Confusions, Complexities, Criminalisation ? Sulphur Emission Control Areas, the Baltic and the North Sea
Why switching to distillates? • A simple solution : • 1. Significant global reduction of emission • SOx, - 60 - 80%, • PM, - 80 - 90%, • NOx, - 15%, • No heavy metals, • Less soot • 2. A more healthy environment for crew and dockworkers • 3. No onboard waste • 4. Reduces overall fuel consumption (and CO2) • 5. Better and easier control or monitoring of ships Cleaner, Simpler and more Efficient ships
Why switching to distillates? • ..continue: • 6. Fewer engine breakdowns and potential pollution accidents • 7. Less pollution when spilled • 8. Provides opportunity for the development of more efficient engines (w. less emission) • 9. Applies to all ships and all • current engines • 10. No safety problem in connection with switching fuels Cleaner, Simpler and more Efficient ships
Switching to distillates CO2 balance • +CO2 emission when continuing to burn HFO: • buffering from scrubbers • higher fuel consumption NOx control • running of scrubbers • heating of HFO • burning handling of waste • running of abatement equipment • +CO2 emission when burning distillates: • conversion of HFO to distillates - which may be balanced by increased power production • construction of conversion plants • handling of waste from conversion plants • less fuel consumption
Status • IMO Group of Experts – report end 2007 • Basic data needed • Status quo- fleet, emission • Costs - investment in refinery upgrading, scrubbers • Costs to the environment and society – pollution, health • Council’s conclusion –2008 • U.S. considers own legislation if the IMO does not deliver IMO Group of Experts will provide figures and need input
Cleaner shipping • INTERTANKO: a long-term practicable measure to reduce emission necessary • Shipping is energy efficient - but burning the dirtiest part of the barrel causes pollution • The oil industry is moving towards cleaner fuels • There are 10 good reasons for switching to distillates • Large investments necessary over a prolonged period - no matter the solution • The costs involved are the costs to the society which will mainly be the impact on the environment (cost effect of increased freight will be marginal)
