The COVID-19 pandemic significantly impacted the shipping industry and especially seafarers, as travel restrictions left tens of thousands of them stranded on ships, or unable to join ships. Access to medical care and repatriation was severely restricted.

IMO worked in collaboration with UN and industry partners, including seafarer organizations, to to find solutions. IMO and other organizations called on governments to designate as "key workers" all seafarers, marine personnel, fishing vessel personnel, offshore energy sector personnel and service provider personnel at ports, regardless of nationality.

IMO treaties need to be implemented into national law so that they can be applied on ships flying the flag of a particular country and so that those countries can implement effective port State control and comply with other obligations under the specified IMO instruments. First lawyers and legislative drafters must understand IMO treaties - how they are developed and adopted. From this, they can see what methods can be used to implement these treaties into national legislation. The drafting of legislation will go through many iterations to ensure they meet the requirements of the IMO treaty whilst accommodating already existing national law.

IMO has been advocating gender equality in the maritime industry for decades. IMO's Women in Maritime programme has been in operation since 1988. This programme's primary objective is to encourage IMO Member States to invite their maritime institutes to train women alongside men and acquire the skill set that the maritime industry demands.

In December 2021 the IMO Assembly adopted a resolution establishing an International Day for Women in Maritime to be observed on 18 May every year. This observance celebrates women in the industry, promotes recruitment, retention and sustained employment of women in the maritime sector, raises the profile of women in maritime, strengthens IMO's commitment to Sustainable Development Goal 5 (gender equality) and supports work to address the current gender imbalance in maritime.

IMO supports the Maritime SheEO Leadership Programme which aims to equip women with the leadership skills and confidence to sit at the shipping decision-making table.

The first IMO-Women's International Shipping and Trading Association (WISTA International) Women in Maritime Survey 2021 examined the proportion and distribution of women working in the maritime sector, from support roles to executive level positions. According to data gathered from Member States, search and rescue teams in national maritime authorities account for significantly fewer women staff (just 10%) as compared to female diplomats (33%) and training staff (30%). Industry data shows that women seafarers make up just 2% of the crewing workforce and are predominately found in the cruise sector, while in shipowning companies they made up 34% of the workforce.

IMO and WISTA have launched the Maritime Speakers Bureau website  to promote women's voices in the shipping industry and increase the number of women speakers. https://maritimespeakers.com/


Interpreters and translators play a crucial role in IMO – and in the entire United Nations. .  By promoting dialogue, tolerance and understanding, multilingualism ensures effective participation of all in the Organization's work, as well as greater transparency and efficiencies and better outcomes. Interpreters and translators facilitate understanding of the technical nuances of maritime terminology.

The six official languages at IMO are: Arabic, Chinese, English, French, Russian and Spanish. IMO Meetings are held with simultaneous interpretation into and from these six languages. Each of these languages has its own department within IMO offering translation, text processing and documentation services.

The working languages of IMO are English, French and Spanish. All meeting documents are provided in the three working languages.

More than 80% of global trade is delivered by sea. This means food, fuel, medicine, are all delivered by seafarers. Without international shipping we would have to rely on other modes of transport which don't have the capacity to carry as much cargo as ships and are not as carbon efficient as international shipping. And this global shipping system has to be supported by a framework of universal standards.

The safety of life at sea has been a key priority for IMO since it began its work in 1959. Over the years, IMO, particularly through the Maritime Safety Committee (MSC), has shaped the way international shipping operates. Codes, conventions and guidelines touch upon every aspect of safety of life at sea, from life-saving appliances, safety of ships in polar waters, guidelines on fatigue, to communications  and more.

IMO has been addressing maritime piracy sine the 1980s. A series of measures, developed in co-operation with Member States and the shipping industry, have helped significantly reduce piracy in the hot spots of the world. In the late 1990s and the early 2000s the focus was on the South China Sea and the Straits of Malacca and Singapore. In the mid-2000s the focus shifted to address piracy off the coast of Somalia, in the Gulf of Aden and the wider Indian Ocean. Today, the number of reported incidents of piracy and armed robbery against ships is significantly lower than previously. In 2021, there were zero reports of piracy off the coast of Somalia.

In 2009, the Djibouti Code of Conduct was adopted, to support the Repression of Piracy and Armed Robbery against Ships in the Western Indian Ocean and the Gulf of Aden.  The IMO Djibouti Code Trust Fund has funded numerous projects, coordinated by the multi-national Project Implementation Unit, to improve regional capacity to counter-piracy by developing enhanced regional cooperation and coordination, in the four pillars of training, capacity building, legal and information sharing.

The scope of the Djibouti Code was expanded in 2017 to include organized crime in the maritime sector, maritime terrorism, human trafficking, and illegal unreported and unregulated fishing. The revised code is known as the Jeddah Amendment to the Djibouti Code of Conduct 2017.

In 1997, IMO adopted a new Annex VI to its MARPOL Convention to address air pollution form ships. The regulations initially addressed the main air pollutants contained in ships exhaust gas, including sulphur oxides (SOx) and nitrous oxides (NOx), and prohibited deliberate emissions of ozone depleting substances (ODS). MARPOL Annex VI also regulates shipboard incineration, and the emissions of volatile organic compounds (VOC) from tankers. Later, in 2011, regulations were added to address energy efficiency of ships  - intended to limit emissions of greenhouse gases.

In 2020, a new lower limit on the sulphur content in fuel oil used on board ships was implemented (often called the "IMO 2020" rule). This measure was introduced due to most ships up to 2020 using heavy fuel oil with a much higher sulphur content compared to other fuel sources. Studies showed the implementation of this new limit, with most ships switching to very low sulphur fuel oil, would mean  a  77% reduction in overall sulphur oxide emissions from ships. This will help reduce  stroke, asthma, lung cancer, cardiovascular and pulmonary diseases, especially in coastal populations. It will also help prevent acid rain and ocean acidification, benefiting crops, forests and aquatic species.

Energy efficiency is an integral part of IMO's aims to achieve greener shipping practices. In 2011, IMO adopted  amendments to MARPOL Annex VIto  introduce compulsory energy efficiency components to ship design and management, promoting the use of less polluting equipment and engines. The amendments were the first legally binding climate change measures for an entire industry sector.

To read more about energy efficiency measures introduced through the MARPOL Annex VI amendments click here.

From 1 January 2023, it is mandatory for all ships to calculate their attained Energy Efficiency Existing Ship Index (EEXI) to measure their energy efficiency and to initiate the collection of data for the reporting of their annual operational carbon intensity indicator (CII) and CII rating. Read the Frequently Asked Questions about these measures here.

To support the implementation of energy-efficiency measures, IMO is implementing a number of global projects.  

One of these is the  Global MTCC Network project. This project established five regional maritime technology cooperation centers who each work with partners to develop technical cooperation, capacity building and technology transfer. Innovative programs and projects carried out by the MTCCs are all designed to promote energy efficient technologies and operations.

In 2018 the IMO's Marine Environment Protection Committee (MEPC) adopted an initial strategy for the reduction of greenhouse gas emissions from ships. Through this initial strategy, IMO Member States pledged to cut annual greenhouse gas emissions from international shipping by at least half by 2025, compared with their level in 2008, and work towards eradicating GHG emissions from shipping entirely.

IMO is championing a comprehensive targeted approach to decarbonizing shipping practices, ensuring that no one is left behind in the global transition towards zero emissions shipping. Through a carbon intensity rating system, IMO hopes to encourage ship owners to use alternative fuels to keep their carbon emissions down.

Developing countries are looking to seize the opportunities that decarbonizing shipping presents.There is great potential for those countries to become key suppliers of low and zero carbon fuels for shipping. Decarbonization of international shipping requires a rapid shift from today's predominant use of fossil fuels to zero-carbon alternatives. And shipping is also a key enabler of the global energy transition as it serves global trade and sustainable development in a safe, clean, efficient and affordable way.

Biofouling is the accumulation of various aquatic organisms on ships' hulls. Through the process of biofouling, invasive aquatic organisms can be introduced to new marine environments affecting the marine biodiversity, coastal properties and infrastructure, and a variety of economic offshore sectors such as fisheries and ocean renewable energy.

To safeguard ecosystem services IMO are leading a global project, GloFouling Parternships, to raise awareness, foster research and development, share best practices and help promote technical solutions to biofouling.

Ocean areas of ecological, socio-economic or scientific significance can be granted special protection status of a Particularly Sensitive Sea Area (PSSA). This status recognizes that the area may be vulnerable to damage by international maritime activities and so enacts guidelines to ensure the protection of the vulnerable space.

PSSA cases require special protective measures which are agreed and adopted, such as the compulsory routeing of ships to avoid these areas altogether.

IMO has been at the forefront of increasing safety in the maritime sector for many years implementing regulations in fishing through the IMO treaty on training for fishers (STCW-F).

Currently,  IMO is raising awareness of a global treaty which when in force will ensure safety of fishing vessels. The Cape Town Agreement will set minimum requirements on the design, construction, equipment, and inspection of fishing vessels of 24 meters in length and over or equivalent in gross tons. Through these measures fishing vessels can be regulated and equipped to ensure efficient safety standards for fishers.

This agreement will also help in combatting illegal, unregulated and unreported fishing, an authorized form of fishing practices which undermines national, regional and global efforts to conserve and manage fish stocks.

When in force, the Cape Town Agreement will provide safe, legal and sustainable shipping providing an internationally-binding standardization of fishing practices.

IMO is committed under its Strategic Plan (2018-2023) to “integrate new and advancing technologies in the regulatory framework”. The organization is working to ensure a regulatory framework for Maritime Autonomous Surface Ships (MASS) that balances the benefits of this rapidly evolving technology with safety, security and environmental concerns, whilst also taking account of its potential cost to the industry and negative impact on international trade.  

Work is underway to establish and adopt by the end of 2024 a non-mandatory MASS Code. IMO then plans to develop a mandatory Code which it hopes will enter into force on 1 January 2028. In the meantime, IMO’s Maritime Safety Committee has approved Interim Guidelines for MASS trials.
