The theme of this year’s International Maritime Organization (IMO) World Maritime Day is ‘Our Ocean – Our Obligation – Our Opportunity’. It reflects the ocean’s vital role as a source of jobs and food for millions of people, a home for countless marine species, and a regulator of the planet's climate, mitigating the impacts of climate change.

As the largest sector operating in the ocean space, shipping has a central role to play in the protection of the marine environment and management of ocean resources.

The IMO's work to protect the ocean

Over many decades, the IMO has developed and adopted mandatory rules, recommendations and guidelines to protect the marine environment from any potential negative impact of shipping.

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.
