1 Objectives
1.1 The purpose of this appendix is to provide Parties with the criteria and procedures
for formulating and submitting proposals for the designation of emission control areas
and to set forth the factors to be considered in the assessment of such proposals by the
Organization.
1.2 Emissions of NOx, SOx and particulate matter from ocean-going ships contribute to
ambient concentrations of air pollution in cities and coastal areas around the world.
Adverse public health and environmental effects associated with air pollution include
premature mortality, cardiopulmonary disease, lung cancer, chronic respiratory ailments,
acidification and eutrophication.
1.3 An emission control area should be considered for adoption by the Organization if
supported by a demonstrated need to prevent, reduce and control emissions of NOx or SOx
and particulate matter or all three types of emissions (hereinafter emissions) from
ships.
2 Process for the designation of emission control areas
2.1 A proposal to the Organization for the designation of an emission control area for
NOx or SOx and particulate matter or all three types of emissions may be submitted only
by Parties. Where two or more Parties have a common interest in a particular area, they
should formulate a coordinated proposal.
2.2 A proposal to designate a given area as an emission control area should be submitted
to the Organization in accordance with the rules and procedures established by the
Organization.
3 Criteria for designation of an emission control area
3.1 The proposal shall include:
-
.1 a clear delineation of the proposed area of application, along with a reference
chart on which the area is marked;
-
.2 the type or types of emission(s) that is or are being proposed for control
(i.e. NOx or SOx and particulate matter or all three types
of emissions);
-
.3 a description of the human populations and environmental areas at risk from the
impacts of ship emissions;
-
.4 an assessment that emissions from ships operating in the proposed area of
application are contributing to ambient concentrations of air pollution or to
adverse environmental impacts. Such assessment shall include a description of the
impacts of the relevant emissions on human health and the environment, such as
adverse impacts on terrestrial and aquatic ecosystems, areas of natural
productivity, critical habitats, water quality, human health, and areas of
cultural and scientific significance, if applicable. The sources of relevant data
including methodologies used shall be identified;
-
.5 relevant information, pertaining to the meteorological conditions in the
proposed area of application, to the human populations and environmental areas at
risk, in particular prevailing wind patterns, or to topographical, geological,
oceanographic, morphological or other conditions that contribute to ambient
concentrations of air pollution or adverse environmental impacts;
-
.6 the nature of the ship traffic in the proposed emission control area, including
the patterns and density of such traffic;
-
.7 a description of the control measures taken by the proposing Party or Parties
addressing land-based sources of NOx, SOx and particulate
matter emissions affecting the human populations and environmental areas at risk
that are in place and operating concurrently with the consideration of measures to
be adopted in relation to provisions of regulations 13 and 14 of Annex
VI; and
-
.8 the relative costs of reducing emissions from ships when compared with
land-based controls, and the economic impacts on shipping engaged in international
trade.
3.2 The geographical limits of an emission control area will be based on the relevant
criteria outlined above, including emissions and deposition from ships navigating in the
proposed area, traffic patterns and density, and wind conditions.
4 Procedures for the assessment and adoption of emission control areas by the
Organization
4.1 The Organization shall consider each proposal submitted to it by a Party or Parties.
4.2 In assessing the proposal, the Organization shall take into account the criteria
that are to be included in each proposal for adoption as set forth in section 3 above.
4.3 An emission control area shall be designated by means of an amendment to this Annex,
considered, adopted and brought into force in accordance with article 16 of the present
Convention.
5 Operation of emission control areas
5.1 Parties that have ships navigating in the area are encouraged to bring to the
Organization any concerns regarding the operation of the area.
