“Our Ocean – Our Obligation – Our Opportunity”, theme of World Maritime Day 2025

The IMO Council, meeting for its 132nd session, has approved the theme for World Maritime Day 2025, to be celebrated on 25 September 2025, as proposed by Mr Arsenio Dominguez, Secretary-General of the IMO.

The theme “Our Ocean – Our Obligation – Our Opportunity” reflects the central role of shipping and the IMO in protecting the oceans and managing marine resources. It also reflects the vital role of the ocean in the global economy, since over 80% of world trade is transported by sea. The ocean is a source of jobs and food for millions of people, a habitat for countless marine species and a regulator of the planet’s climate, mitigating the effects of climate change.

Arsenio Dominguez, Secretary-General of the IMO, says: “Our long-standing commitment on this issue is evident in IMO’s robust global regulatory framework supporting cleaner, safer seas, and a growing portfolio of technical assistance initiatives to support ocean protection in our 176 Member States.”

Over many decades, IMO has developed and adopted mandatory rules, recommendations and guidelines to protect the marine environment from any potential negative impact of shipping. These include binding treaties applied on ships globally. The International Convention for the Prevention of Pollution from Ships (MARPOL), first adopted in 1973, covers pollution from oil, dangerous chemicals, packaged goods, sewage and garbage, and harmful emissions from ships.

Other marine environment related treaties cover: the dumping of wastes at sea (London Convention and Protocol); managing ships’ ballast water to prevent the spread of potentially invasive aquatic species (Ballast Water Management Convention); control of anti-fouling systems; and preparedness and response for spills of oil or chemicals.

These international regulations are supported by technical assistance programmes and projects that support Member States to tackle specific challenges such as marine plastic litter, greenhouse gas emissions from ships, and the spread of invasive aquatic species through ballast water and biofouling.

IMO’s work in these areas directly support the UN 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs), particularly:

SDG 14 on life below water;
SDG 13 on climate action;
SDG 9 on industry, innovation and infrastructure; and
SDG 17 on partnerships.

The new theme emphasizes the link to wider global efforts to protect the ocean including the conclusion of UN Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement), the negotiation of a new instrument to address plastic pollution and the third UN Ocean Conference in June 2025.

The theme will allow all stakeholders to showcase the deep interconnection of shipping and IMO in the ocean space, highlighting the importance of collaboration and coordination to ensure the sustainable and safe use of ocean resources.
