World Maritime Day History

World Maritime Day was first celebrated in 1978 to mark the convention of the International Maritime Organization. Since this event, the day has been observed annually on the last Thursday of September. 

The IMO, as a specialised UN agency, leads efforts in maritime governance. It sets global standards for ship safety, marine pollution prevention, and navigation rules. The day also acknowledges shipping as the backbone of global trade. More than 80% of goods are transported by sea, linking producers and markets across continents.

Over the decades, World Maritime Day has become an opportunity to reflect on achievements, challenges, and new commitments. Each year carries a theme that guides global discussions. In 2025, the focus is on uniting responsibility and opportunity to protect oceans.

World Maritime Day 2025 Theme

The World Maritime Day 2025 theme is “Our Ocean, Our Obligation, Our Opportunity.” This theme reflects the shared responsibility of nations to care for the ocean while recognising opportunities for progress.

It emphasises the need for stronger international cooperation, cleaner shipping practices, and protection of marine ecosystems. The theme also signals innovation in maritime technologies. IMO’s choice reminds the world that ocean sustainability is linked with human well-being, economic development, and climate stability.

Shipping, Ocean, and Global Economy

Shipping is central to the world economy. Through this, all the major or, say, essential goods like food, energy, and medicines are shipped. Around 80–90% of global trade is carried by sea. 

The ocean also regulates the climate by absorbing heat and carbon. It provides jobs to millions in fishing, transport, and tourism. Marine resources supply food and energy. However, this reliance comes at a cost.

Shipping activities can lead to emissions, oil spills, underwater noise, and habitat destruction. Balancing the benefits of shipping with the need for sustainability is a key challenge in 2025.

IMO’s Regulatory and Environmental Role 

The IMO is the key body for international maritime rules. Its work has shaped safer, cleaner, and more efficient shipping. Notable agreements include:

• MARPOL Convention – prevention of marine pollution.
• Ballast Water Management Convention – control of invasive species.
• Conventions on emissions – reduction of sulfur oxides, nitrogen oxides, and greenhouse gases.

IMO also supports capacity building for developing nations. It ensures that maritime safety and environmental standards are applied globally.

In 2025, IMO’s work is tied to the World Maritime Day 2025 theme, reminding the world of obligations to act and opportunities to innovate.

World Metrology Organization

The World Metrology Organization plays a critical role in shipping and ocean activities. Measurement science ensures safety and accuracy in maritime operations.

Precise measurements help in forecasting weather, waves, and sea states. These are vital for navigation and preventing accidents. Accurate monitoring also supports pollution control and emission tracking.

Instruments on ships need to follow the same global rules so they can work safely everywhere. The World Metrology Organization makes these rules and helps keep ships safe while also protecting the environment.

By making sure data about sea levels, temperatures, and emissions is correct, the World Metrology Organization helps countries manage the oceans better. This work is an important part of the idea behind World Maritime Day 2025.
