  3. Drivers of Change • Society is driving the requirement for ships to reduce harmful air emissions from engine exhausts – particularly in Europe and the US and to a lesser extent in Japan and elsewhere • Legislators, regulators and others are taking action and planning more • The IMO has initiated a revision process for MARPOL Annex VI States and industry are united in trying to ensure that Air Emissions are regulated internationally through the IMO

  4. EU Thematic Strategy on Air PollutionCOM(2005) 446 & SEC(2005) 1132 and 1133 (Adopted Sept. 2005) & Role of Maritime Emissions DG Environment, European Commission

  5. Impacts addressed by the Strategy • Health: Fine Particles (PM2.5) & Ozone (NOx and VOCs) • Range of problems from minor respiratory effects to premature death; also cardiovascular effects. No known thresholds for effects • Acid rain (SO2, NOx, NH3) • Affects freshwaters and terrestrial ecosystems leads to loss of flora & fauna; reduced growth of forests, leaching of toxic metals into soil solution • Eutrophication (NOx, NH3) • Excess nutrient nitrogen causes species composition change & loss of biodiversity. Increases susceptibility to other stresses such as drought • Ozone (non-health, NOx and VOCs) • Damages trees and plants including agricultural crops; damages buildings/materials

  6. Fine particles PM2.5Life expectancy:8.1 months in 2000, 5.5 months in 2020Life years lost:3.6M in 20002.5M in 2020Premature deaths350,000 in 2000 272,000 in 20201997 Met. year months

  7. Problem of too much nitrogen deposited to ecosystems in 2020 Percentage of ecosystem area in each model grid cell with nitrogen deposition above “safe level” % Total Ecosystem area exceeded from eutrophication 590 000 km2 1997 met. year

  8. Summary of “Business as Usual”(includes current ship measures) • Emissions continue to decline • But in 2020 • Premature deaths related to fine particulates still 270,000 • Loss of statistical average life still 5 months in the EU • Ozone premature mortality equal to 20,800 cases • 119,000 km2 of forest at risk from acid rain • 590,000 km2 of ecosystems at risk from nutrient Nitrogen • 760,000 km2 of forest at risk from ozone • Cost-effective improvements are possible Emissions Ships will represent 125% and 101% of land based SO2 and NOx emissions in 2020.

  9. Air Pollution from Ships • Many measures taken on land based sources to reduce polluting emissions (Large Combustion Plant, road vehicles, fuels etc.) • Community Marine Emissions Strategy of 2002 lead to the adoption of Directive 2005/33/EC on the sulphur content of marine fuels • SOx emission control areas – 1.5% S fuels • Marine gas oils used at berth from 2010 (0.1%) • This has already been factored into Commission’s analyses for the Thematic Strategy

  10. Mandate to do more on NOx emissions from ships (1) • European Parliament response to the Marine emissions strategy of 2002 • “Notes the Commission's intention to bring forward a proposal to reduce NOx emissions from seagoing vessels ….. but is concerned that the Commission links this action to future developments in the IMO, i.e. the Commission will only take this action if by the end 2006 the IMO has not proposed tighter international NOx standards • Calls on the Commission to - before the end of 2004 - come forward with a proposal for NOx emission standards for ships which is based on the use of best available techniques (BAT), and which aims at reducing NOx-emissions from ship engines, and to pursue such BAT-based NOx-emission standards to be accepted also by the IMO;”

  11. Mandate to do more on NOx emissions from ships (2) • Council Conclusions on the marine emissions strategy of 2002 Para 12. “Considers that is essential to reinforce the consideration of EU MS’ positions at IMO negotiations in particular to PROMOTE, in the revision phases of Annex VI, the adoption of more ambitious measures as regards a tighter global sulphur cap for heavy fuel oils burned by ships and tighter nitrogen dioxide emission standards for engines used in ships” Para 15. “RECOGNISES that progress within IMO depends on the input of IMO member states and therefore URGES the EU Member States to submit concrete proposals on tighter NOx standards under MARPOL Annex VI and on the different aspects of the IMO GHG Strategy. Para 16. “RECOGNISES the need to investigate specific EU actions with respect to the reduction of NOx and GHG emissions by marine transportation; INVITES the Commission to consider a proposal for tighter NOx standards by the end of 2006 if IMO has not made any proposals for tighter standards by that date”

  12. Mandate to do more on emissions from ships (3) • EP Resolution on the Air Thematic Strategy (Sept 2006) • Establish NOx emission standards for ships using EU Ports • Designate the Mediterranean Sea and North East Atlantic as SECAs • Lower sulphur content of marine fuels used in SECAs to 0.5% • Introduce financial instruments such as SOx and NOx taxes • Encourage differentiated port and fairway charges favouring low emission operation • Encourage use of shore-side electricity by ships in ports. • Proposal on marine fuel quality in the EU • Calls on the Commission to propose coordinate action to ensure a level playing field and to insist on action within the IMO; is convinced that a better balance between the costs of reducing emissions from ships and land-based sources is needed. • Council Conclusions of March 2006 called on the Commission to continue its efforts to reduce ships’ emissions

  13. EU DG Env: What next? • BLG : 16 -20 April 2007 • MEPC 56: 9-13 July 2007 • Commission to take stock of progress • Review of Directive 1999/32/EC on the sulphur content of fuels & marine fuels – 2008 • Scope for Community measures to reduce ship emissions pursuant to Council’s conclusions - 2008

  14. EU: Further information • Ship emissions policy and technical studies http://ec.europa.eu/environment/air/transport.htm • Thematic Strategy on air pollution & CAFE http://ec.europa.eu/environment/air/cafe/index.htm • National emissions ceilings directive http:/ec.europa.eu/environment/air/ceilings.htm

  15. US EPA Submission (to BLG) • Air pollution from ocean going vessels (OGVs) is a significant source of damage to human health …… its overall contribution is rapidly growing. • In 15 years since the MEPC began discussions on air emissions, only limited progress has been made toward reducing these emissions. While the sulphur content of marine fuel oil has been capped at 45,000 ppm, the vast majority of fuel never exceeded that level and the global sulphur cap has resulted in little, if any, reduction in sulphur emissions. …, This fuel sulphur cap is set at a level 3,000 times higher than is commonly now used in land-based transportation. • The consequence of OGVs achieving only modest improvement in air emissions, while all other transportation sources are making continued improvement, is that OGVs are now one of the largest anthropogenic sources of air pollution… Recent estimates in the scientific community indicate OGVs represent approx.18-30% of the world’s NOx pollution & 9% of global SOx emissions. • IMO Member States now hold a unique opportunity to revise the MARPOL Annex VI engine and fuel standards in a manner that will provide a long-term solution to the significant air emissions generated by ships.

  16. JAPANESE Submission (to BLG) NOx reductions / NECA proposal New engines Japan also supports a two-step approach, 2010 for Tier II and tentatively 2015 for Tier III. Basically, the NOx emission limits should be set to reduce the NOx emissions from ships as much as possible. Japan also has a project of NOx reduction technologies development. The target date of this project is 2012 and its goal is nearly 80% NOx reduction. At the same time, we propose to introduce geographically-based standard for Tier III, taking into account that there is trade-off relationship between the NOx emission and CO2 emission and that the effect to the environment by NOx is local while the greenhouse effect by CO2 is global. Existing engines In order to reduce the total amount of NOx emissions from ships, existing engines should also be regulated. The NOx emission limits and range of existing engines to be regulated should be appropriately determined, taking into account the effect to the environment, their life time, the trend in development of new technologies and so on.

  17. Air Emissions from Ships • Covered by Annex VI • Oxides of Nitrogen (NOx) – create Ozone • Sulphur Oxides (SOx) – create acidification • Hydrocarbons (HC) – gas, soot and some particulates • Volatile Organic Compounds (VOC) • Refrigerant Gases • Not covered (currently) by Annex VI • Carbon Dioxide (CO2) • Carbon Monoxide (CO) Engine exhaust gases are dependent upon engine type, engine settings and fuel type

  18. New Parameter for Air Pollution Control ? • Particulate Matter Emission control • What are these Particulates? • Sulphates from SOx • Nitrates from NOx • VOC from uncombusted hydrocarbons • Heavy Metals e.g. Vanadium, Nickel, Aluminium, Sodium, Calcium, Zinc; from Heavy Fuel oil and Lube Oil • Soot – from the aromatics in heavy fuel oil
