Parties to the treaties which regulate the dumping of wastes at sea have reiterated, in a statement, their concern about marine engineering techniques, which have the potential for deleterious effects that are widespread, long-lasting or severe. They state that such marine geoengineering activities, other than legitimate scientific research, should be deferred.
The statement was adopted by the 45th Consultative Meeting of Contracting Parties to the London Convention and the 18th Meeting of Contracting Parties to the London Protocol (LC 45/LP 18), which met 2-6 October 2023.
