The Bonn Agreement is the mechanism by which ten Governments, together with the European Union, cooperate in dealing with pollution of the North Sea by oil and other harmful substances. The signatories to the Agreement are the Governments of Belgium, Denmark, France, Germany, Ireland, Netherlands, Norway, Sweden, the UK, and the European Union.
