During the conference, IMO welcomed the launch of the High Ambition Coalition for a Quiet Ocean – a group of 37 countries led by Canada and Panama committed to tackling underwater noise pollution. 

An official side event co-organized by IMO with the Governments of France Costa Rica and South Africa highlighted IMO’s work on this issue,

Invasive aquatic species

IMO is actively addressing the threat of invasive species which accumulate on ships’ hulls (known as biofouling) and get transferred to new marine ecosystems. 

During a side event co-organized by IMO with the Governments of Norway and Fiji, speakers showcased regulatory and technical support actions in this area,

Marine plastic pollution 

IMO’s International Convention for the Prevention of Pollution from Ships (MARPOL, Annex V) prohibits the discharge into the marine environment of most types of garbage from ships, including plastics, and outlines standards for waste management. The London Convention/Protocol bans deliberate dumping of wastes at sea.   

In line with this, the IMO is taking the following initiatives:

• IMO Strategy and 2025 Action Plan to Address Marine Plastic Litter from Ships aims to reduce plastic pollution from vessels, improve port waste facilities, improve awareness and training of seafarers, and strengthen international cooperation;
• Technical assistance provided by the OceanLitter Programme (IMO-FAO) including three key projects - GloLitter, RegLitter and PRO-SEAS. These focus on legal and policy reform to align with international regulations, enhance port reception facilities and advance gear marking systems.

During the Conference, a new Global Industry Alliance was announced for action on marine plastic pollution, with industry actors and members of the private sector invited to join.

Secretary-General Dominguez urged the international community to ramp up activities and deliver meaningful progress ahead of the next UN Ocean Conference in 2028, to be hosted by Chile and the Republic of Korea.
