drivers of change
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

eu thematic strategy on air pollution
EU Thematic Strategy on Air Pollution
  • 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

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.

eu action to date on air pollution
EU action to date on Air Pollution
  • 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
eu has mandate for more action on air pollution from ships 1
EU has mandate for more action on Air Pollution from ships (1)

European Parliament

  • In 2002, “Commission to take action by end 2006 if IMO has not proposed tighter international NOx standards”
  • In 2006, Resolution:
    • 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.
eu has mandate for more action on air pollution from ships 2
EU has mandate for more action on Air Pollution from ships (2)

Council of Ministers (EU)

  • In 2002, Conclusions:

- “Reinforce consideration to promote in revision of Annex VI more ambitious measures as regards tighter global sulphur cap .. and tighter NO2 standards.”

- “Urges EU Member States to submit proposals on tighter NOx standards under Annex VI.”

- “Invites Commission to take action by end 2006 if IMO has not proposed tighter international NOx standards.”

  • In 2006, Conclusions:

- “Commission to continue its efforts to reduce ships’ emissions.”

  • 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.

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.

governing regulations
Governing Regulations
  • MARPOL Annex VI adopted in 1997 and entered into effect in 2005

- Baltic Sea - SECA from May 2006

- North Sea - SECA in November  2007

  • Europe Sulphur Directive (1999 & Rev) governs inter alia emissions in port (0.1% S at berth)
  • California (CARB): new regulations which took effect Jan 2007
  • Various ports

- local regulations on Ship Emissions, which inter alia are inhibiting future expansion/development

- introducing differentiated port fees

Of particular concern to tramp sectors, trading internationally, lifting bunkers in ports worldwide

  • be realistic and feasible
  • seek a long term and positive reduction of air emissions from ships, and
  • contribute to a long term and a predictable regulatory regime
revision of marpol annex vi intertanko suggestion
REVISION OF MARPOL ANNEX VIINTERTANKO SUGGESTION

FOR DISCUSSION

  • Distillate fuels & 2-tiered S cap program:
    • from [2010], a maximum of 1.00% S content
    • for ships’ engines installed on and after [2015], a maximum [0.50]% S content
  • A Global Sulphur Emission Control Area
  • A New Fuel specification in Annex VI
  • Simpler monitoring of compliance
distillate mdo advantages air emissions
Distillate/MDO Advantages:AIR EMISSIONS
  • Applies to ALL existing ships/engines
  • With no other measure, immediately reduces:
    • SOx emissions by 80% to 90%
    • PM emissions by 90%
    • NOx emissions by 10% to 15%
  • Reduces fuel consumption with some 4%

from ALL ships and thus CO2 emissions

  • Facilitates further NOx reductions by in-engine modifications for IMO’s Tier II & III
distillate mdo advantages air emissions29
Distillate/MDO Advantages:AIR EMISSIONS
  • Engines designed for use of MDO only will accommodate further emission reductions over their entire life time
  • Further regulatory reduction of air emissions from ships will be a function of better quality fuels and not be limited by engine’s functional parameters
distillate mdo additional benefits
Distillate/MDO :ADDITIONAL BENEFITS
  • ENVIRONMENTAL:
    • Reduces onboard fuel generated waste
    • No fuel heating/pre-treatment or waste incineration = energy saving
    • ALL ships become “greener”
    • “Cleaner” waste & free of hazardous elements contained in residual fuels
    • Avoids use of abatement technologies = no further additional waste & no need of further waste disposal
    • [Any bunker spill significantly less harmful]
  • SAFETY:
    • Less incidents with engine breakdowns caused by poorer quality fuels / lower maintenance load
    • No need of complex fuel change-over operations
    • No risk of incompatibility of blended fuels
    • Safer working environment for crews

At what cost and who takes responsibility ?

  • High sulphur residual with abatement technology such as scrubbers, etc.
  • Low sulphur residual
  • Combination HS/LS residual
  • MDO (Low sulphur)
  • Other combinations
co 2 emissions net environmental benefit
CO2 Emissions – Net Environmental Benefit
  • Additional refinery CO2 emissions from de-sulphurisation of residuals
  • Additional refinery CO2 emissions from MDO production/distillation
  • Ship CO2 emissions lower with MDO due to lower fuel consumption
  • Ship CO2 emissions lower with MDO since no need to heat residual fuels prior treatment & injection
  • High CO2 emissions in manufacturing & operating scrubbers
  • Higher CO2 emissions with catatylic converters when using residual fuels rather than distillates
volatile organic compounds voc emissions their control
Volatile Organic Compounds (VOC) Emissions & their Control

VOCs generated both during loading and on passage

  • Vapour return lines used in some ports
  • INTERTANKO developed VOC control procedure (VOCON) with potential to reduce by more than 70% VOC emissions on passage
  • System further enhanced by adoption of the Pres-Vac VOCON P/V valve
  • Further industry development with KVOC loading system

  • NOx emissions - reduction by 80% by a combination of fuel quality, in engine technology and after treatment technology.

Sweden

  • SOx & PM emissions - use of MDO with a lower sulphur content, most likely in a two tier step at dates to be established by IMO.
what next41
What next?
  • Annex VI or VII ? – Scrubber / Catalytic Converter toxic waste handling
  • Biomass (marine bio-diesel) – to assist in achieving a 20% reduction target for CO2
  • Emissions trading – extended to shipping
  • Sequestration of CO2 / Carbon capture
current position
Current position
  • INTERTANKO encourages open debate on the options available to reduce damaging air emissions from ships and has sought to provide for discussion comprehensive solutions that are applicable on a global basis.
  • We remain anxious that the current reviews around the world do not result in a mix of local and regional requirements that impose an onerous burden on international shipping, especially those engaged in tramp shipping - bunkering in and trading to ports around the world.
  • We continue to stress the importance that any new requirements should take full account of all the operational and safety considerations, and should be assessed on the same basis - this latter should involve the cost and environmental implications of all the production, manufacturing, operating and waste handling aspects of the proposed system, as well as other practicalities with respect to introduction, fitting/retrofitting, etc.
