Lisbon Agreement




The accidents that polluted the French, Spanish, Moroccan and Portuguese coasts, including the Aragon’s shipwreck in Madeira in 1990, demonstrated the need for a regional agreement to combat marine pollution, covering the waters of the Northeast Atlantic.

Thus in 1990 the Portuguese Government made a proposal to the European Commission. 

On 17 October 1990, Portugal, France, Morocco, Spain and the then European Economic Community have signed the agreement for the protection of the Northeast Atlantic’s coasts and waters, or Lisbon Agreement.

On 20 May 2008, an Additional Protocol was signed that modified the southern limit.

The Lisbon Agreement is a mechanism to ensure cooperation between the Contracting Parties in the event of a pollution incident at sea. The Agreement requires the Contracting Parties to set up their own system of prevention and control, to equip themselves with pollution control equipment and to set their own national plans of action.

The Lisbon Agreement is in force since 1 February 2014 after all parties have deposited their respective instruments of ratification.




Contribute to the development and joint establishment of a set of directives on the practical, operational and technical aspects of a joint action against pollution of the marine environment by hydrocarbons and other harmful substances in the area covered by the Agreement.

Strengthen the capacity for mutual assistance and facilitate the cooperation between the Contracting Parties to the Agreement in the fight against marine pollution by hydrocarbons and other harmful substances.

Contribute and assist the Contracting Parties in order to install and equip pollution control authorities capable of acting quickly and effectively in the event of a pollution incident or accident, in accordance with established and pre-trained national contingency plans.

Assist Contracting Parties to the Agreement, when such help is need, to establish a rapid and effective way of acting to combat pollution caused by hydrocarbons and other harmful substances.

Establish communication and operational systems to facilitate information exchange, technical cooperation and training between the Contracting Parties. 

Sensitize the Contracting Parties to the Agreement to ensure compliance with other International Conventions in the area of marine pollution.
