CONVENTION ON THE PREVENTION OF MARINE POLLUTION BY 
DUMPING OF WASTES AND OTHER MATTER

(London, Mexico City, Moscow and Washington, 29 December 
1972)

Preamble

The Contracting Parties to this Convention

Recognizing that the marine environment and the living 
organisms which it supports are of vital importance to 
humanity, and all people have an interest in assuring 
that it is so managed that its quality and resources are 
not impaired;

Recognizing that the capacity of the sea to assimilate 
wastes and render them harmless, and its ability to 
regenerate natural resources, is not unlimited;

Recognizing that States have, in accordance with the 
Charter of the United Nations and the principles of 
international law, the sovereign right to exploit their 
own resources pursuant to their own environmental 
policies, and the responsibility to ensure that 
activities within their jurisdiction or control do not 
cause damage to the environment of other States or of 
areas beyond the limits of national jurisdiction;

Recalling Resolution 2749 (XXV) of the General Assembly 
of the United Nations on the principles governing the 
sea-bed and the ocean floor and the subsoil thereof, 
beyond the limits of national jurisdiction;

Noting that marine pollution originates in many sources, 
such as dumping and discharges through the atmosphere, 
rivers, estuaries, outfalls and pipelines, and that it is 
important that States use the best practicable means to 
prevent such pollution and develop products and processes 
which will reduce the amount of harmful wastes to be 
disposed of;

Being convinced that international action to control the 
pollution of the sea by dumping can and must be taken 
without delay but that this action should not preclude 
discussion of measures to control other sources of marine 
pollution as soon as possible and;

Wishing to improve protection of the marine environment 
by encouraging States with a common interest in 
particular geographical areas to enter into appropriate 
agreements supplementary to this Convention;

Have agreed as follows:

Article 1

Contracting Parties shall individually and collectively 
promote the effective control of all sources of pollution 
of the marine environment, and pledge themselves 
especially to take all practicable steps to prevent the 
pollution of the sea by the dumping of waste and other 
matter that is liable to create hazards to human health, 
to harm living resources and marine life, to damage 
amenities or to interfere with other legitimate uses of 
the sea.

Article 2

Contracting Parties shall, as provided for in the 
following Articles, take effective measures individually, 
according to their scientific, technical and economic 
capabilities, and collectively, to prevent marine 
pollution caused by dumping and shall harmonize their 
policies in this regard.

Article 3

For the purposes of this Convention:

1.a. "Dumping" means:

(i) any deliberate disposal at sea of wastes or other 
matter from vessels, aircraft, platforms or other man-
made structures at sea; 

(ii) any deliberate disposal at sea of vessels, aircraft, 
platforms or other man-made structures at sea;

b. "Dumping" does not include:

(i) the disposal at sea of wastes or other matter 
incidental to, or derived from the normal operations of 
vessels, aircraft, platforms or other man-made structures 
at sea and their equipment, other than wastes or other 
matter transported by or to vessels, aircraft, platforms 
or other man-made structures at sea, operating for the 
purpose of disposal of such matter or derived from the 
treatment of such wastes or other matter on such vessels, 
aircraft, platforms or structures;

(ii) placement of matter for a purpose other than the 
mere disposal thereof, provided that such placement is 
not contrary to the aims of this convention;

c. The disposal of wastes or other matter directly 
arising from, or related to the exploration, exploitation 
and associated off-shore processing of seabed mineral 
resources will not be covered by the provisions of this 
Convention.

2. "Vessels and aircraft" means waterborne or airborne 
craft of any type whatsoever. This expression includes 
air cushioned craft and floating craft, whether self-
propelled or not.

3. "Sea" means all marine waters other than the internal 
waters of States.

4. "Wastes or other matter" means material and substance 
of any kind, form or description.

5. "Special permit" means permission granted specifically 
on application in advance and in accordance with Annex II 
and Annex III.

6. "General permit" means permission granted in advance 
and in accordance with Annex III.

by the Contracting Parties in accordance with Article 
14.2.

Article 4

1. In accordance with the provisions of this Convention, 
Contracting Parties shall prohibit the dumping of any 
wastes or other matter in whatever form or condition 
except as otherwise specified below:

a. the dumping of wastes or other matter listed in Annex 
I is prohibited;

b. the dumping of wastes or other matter listed in Annex 
II requires a prior special permit;

c. the dumping of all other wastes or matter requires a 
prior general permit.

2. Any permit shall be issued only after careful 
consideration of all the factors set forth in Annex III, 
including prior studies of the characteristics of the 
dumping site, as set forth in Sections B and C of that 
Annex.

3. No provision of this Convention is to be interpreted 
as preventing a Contracting Party from prohibiting, 
insofar as that Party is concerned, the dumping of wastes 
or other matter not mentioned in Annex I. That Party 
shall notify such measures to the Organisation.

Article 5

1. The provisions of Article 4 shall not apply when it is 
necessary to secure the safety of human life or of 
vessels, aircraft, platforms or other man-made structures 
at sea in cases of force majeure caused by stress of 
weather, or in any case which constitutes a danger to 
human life or a real threat to vessels, aircraft, 
platforms or other man-made structures at sea, if dumping 
appears to be the only way of averting the threat and if 
there is every probability that the damage consequent 
upon such dumping will be less than would otherwise 
occur. Such dumping shall be so conducted as to minimize 
the likelihood of damage to human or marine life and 
shall be reported forthwith to the Organisation.

2. A Contracting Party may issue a special permit as an 
exception to Article 4.1.a, in emergencies, posing 
unacceptable risk relating to human health and admitting 
no other feasible solution. Before doing so the Party 
shall consult any other country or countries that are 
likely to be affected and the Organisation which, after 
consulting other Parties, and international organizations 
as appropriate, shall, in accordance with Article 14 
promptly recommend to the Party the most appropriate 
procedures to adopt. The Party shall follow these 
recommendations to the maximum extent feasible consistent 
with the time within which action must be taken and with 
the general obligation to avoid damage to the marine 
environment and shall inform the Organisation of the 
action it takes. The Parties pledge themselves to assist 
one another in such situations.

3. Any Contracting Party way waive its rights under 
paragraph 2 at the time of, or subsequent to ratification 
of, or accession to this Convention.

Article 6

territory or flying its flag, when the loading occurs in 
the territory of a State not party to this Convention.

3. In issuing permits under sub-paragraphs 1.a and b 
above, the appropriate authority or authorities shall 
comply with Annex III, together with such additional 
criteria, measures and requirements as they may consider 
relevant.

Secretariat established under a regional agreement, shall 
report to the Organisation, and where appropriate to 
other Parties, the information specified in sub-
paragraphs c and d of paragraph 1 above, and the 
criteria, measures and requirements it adopts in 
accordance with paragraph 3 above. The procedure to be 
followed and the nature of such reports shall be agreed 
by the Parties in consultation.

Article 7

1. Each Contracting Party shall apply the measures 
required to implement the present Convention to all:

a. vessels and aircraft registered in its territory or 
flying its flag; 

b. vessels and aircraft loading in its territory or 
territorial seas matter which is to be dumped;

c. vessels and aircraft and fixed or floating platforms 
under its jurisdiction believed to be engaged in dumping.

2. Each Party shall take in its territory appropriate 
measures to prevent and punish conduct in contravention 
of the provisions of this Convention.

procedures for the effective application of this 
Convention particularly on the high seas, including 
procedures for the reporting of vessels and aircraft 
observed dumping in contravention of the Convention.

4. This Convention shall not apply to those vessels and 
aircraft entitled to sovereign immunity under inter-
national law. However each Party shall ensure by the 
adoption of appropriate measures that such vessels and 
aircraft owned or operated by it act in a manner consist-
ent with the object and purpose of this Convention, and 
shall inform the Organisation accordingly.

5. Nothing in this Convention shall affect the right of 
each Party to adopt other measures, in accordance with 
the principles of international law, to prevent dumping 
at sea.

Article 8

In order to further the objectives of this Convention, 
the Contracting Parties with common interests to protect 
the marine environment in a given geographical area shall 
endeavour, taking into account characteristic regional 
features, to enter into regional agreements consistent 
with this Convention for the prevention of pollution, 
especially by dumping. The Contracting Parties to the 
present Convention shall endeavour to act consistently 
with the objectives and provisions of such regional 
agreements, which shall be notified to them by the 
Organisation. Contracting Parties shall seek to co-
operate with the Parties to regional agreements in order 
to develop harmonized procedures to be followed by 
Contracting Parties to the different conventions 
concerned. Special attention shall be given to co-
operation in the field of monitoring and scientific 
research.

collaboration within the Organisation and other 
international bodies, support for those Parties which 
request it for:

a. the training of scientific and technical personnel;

b. the supply of necessary equipment and facilities for 
research and monitoring;

c. the disposal and treatment of waste and other measures 
to prevent or mitigate pollution caused by dumping; 
preferably within the countries concerned, so furthering 
the aims and purposes of this Convention.


Article 10

In accordance with the principles of international law 
regarding State responsibility for damage to the 
environment of other States or to any other area of the 
environment, caused by dumping of wastes and other matter 
of all kinds, the Contracting Parties undertake to 
develop procedures for the assessment of liability and 
the settlement of disputes regarding dumping.

Article 11

The Contracting Parties shall at their first consultative 
meeting consider procedures for the settlement of 
disputes concerning the interpretation and application of 
this Convention.
