Our policy Work on the London Convention & Protocol

The Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter 1972 - the "London Convention" for short - is one of the first global conventions to protect the marine environment from human activities. It has been in force since 1975 and is the most widely applicable international regulatory instrument. Some 90 States are parties to this Convention. In 1996, the"London Protocol" was agreed to further modernize the Convention and, eventually, replace it. Currently there are about 50 parties to the Protocol.

The objective of both the London Convention and its Protocol is to promote the effective control of all sources of marine pollution and to take all practicable steps to prevent pollution of the sea by dumping of wastes and other matter. Read more about the London Convention & Protocol - LC/LP.

CEDA's role

The official observer at the London Convention and its Protocol is the World Organisation of Dredging Associations (WODA).  CEDA undertakes this work on behalf of WODA and actively participates in meetings, and relevant working groups, to provide independent expert advice and help shape policy development.

CEDA has a long history of working with the LC/LP (we were granted observer status in 1990). We are proud to be a recognised source of unbiased technical knowledge, and best practice, on all aspects of dredging and management of dredged sediments. Topics of particular relevance to us on the LC agenda include: contamination caused by dredged material; underwater noise; marine spatial planning and climate change adaptation.

As a member of the drafting group we participated in the production of the first dredged material guidelines and the subsequent revisions including the most recent one in 2012-2013. We produced the "Training set extension for the application of low-technology techniques for assessing dredged material". We regularly present the CEDA position and information papers at meetings of the Scientific Groups of LC/LP.
