Marine pollution is a pressing issue that threatens the health of our oceans and seas. To combat this, the International Convention for the Prevention of Pollution from Ships, or MARPOL, was adopted in 1973 and later revised by the protocol in 1978. This convention aims to minimise marine pollution from ships, including dumping, oil and air pollution, and has six technical annexes with various chapters and regulations. MARPOL Annex I, for example, addresses the discharge of oil into the ocean, while MARPOL Annex VI focuses on air pollution from ships, including nitrogen oxide and sulphur oxide emissions. With regular updates and enforcement through organisations like the EPA and USCG, MARPOL is a dynamic tool in the fight against marine pollution, ensuring shipping remains an environmentally sustainable mode of transport.

What You'll Learn
MARPOL's role in tackling oil pollution
The International Convention for the Prevention of Pollution from Ships (MARPOL) is the main international convention covering the prevention of marine pollution by ships from operational or accidental causes. It was adopted by the International Maritime Organization (IMO) on 2 November 1973 and came into force on 2 October 1983.
MARPOL has been instrumental in tackling oil pollution from ships. Its role in this area is primarily defined in Annex I, which focuses on the prevention of pollution by oil. This annex sets out specific measures to address oil spills and the discharge of oil into the sea. For instance, it mandates the use of double hulls for oil tankers, which provides an additional layer of protection to prevent oil leaks.
Annex I also establishes requirements for oil spill response plans and the handling of oil transfers to prevent spills. It further includes provisions for the monitoring and reporting of discharges and emissions, aiding authorities in tracking compliance and identifying areas for improvement.
In addition to Annex I, other annexes of MARPOL also contribute to tackling oil pollution. For example, Annex II addresses the control of pollution by noxious liquid substances in bulk, which can include oil-based products. Annex VI, which addresses air pollution from ships, also plays a role in reducing oil pollution by setting limits on sulphur oxide and nitrogen oxide emissions from ship exhausts.
Over the years, MARPOL has been successful in reducing oil spill incidents. According to one source, oil spills have decreased by over 90% in the last 50 years, significantly reducing the harmful impact on marine ecosystems. This demonstrates the effectiveness of MARPOL's regulations and its role in tackling oil pollution from ships.

Air pollution and ozone-depleting substances
The International Convention for the Prevention of Pollution from Ships, or MARPOL, is the primary international convention addressing marine pollution caused by ships' operations or accidents. The convention has been modified through the years and currently includes six technical annexes.
MARPOL Annex VI addresses air pollution from ocean-going ships. The international air pollution requirements of Annex VI establish limits on nitrogen oxides (NOx) emissions and require the use of fuel with lower sulfur content, reducing ozone-producing pollution, which can cause smog and aggravate asthma. The use of lower-sulfur fuel also reduces emissions of sulfur oxides (SOx). The requirements apply to vessels operating in US waters and within 200 nautical miles of the North American coast, known as the North American Emission Control Area (ECA).
Annex VI prohibits the deliberate emission of ozone-depleting substances, including halons and chlorofluorocarbons (CFCs). New installations containing these substances are prohibited on all ships. However, new installations containing hydro-chlorofluorocarbons (HCFCs) were permitted until January 1, 2020.
The ozone layer is crucial for protecting the Earth from harmful UV radiation. In the past few decades, it has become evident that the ozone layer is depleting due to the excessive use of substances containing CFCs. This has severe implications for humans, plants, and animals.
To address air pollution from ships, a MARPOL regulation called the Prevention of Air Pollution from Ships was implemented on May 19, 2005. This regulation mandates that all ships exceeding 400 gross tons and constructed before May 19, 2005, must possess an International Air Pollution Prevention (IAPP) certificate. Additionally, an ozone-depleting substance record book must be maintained onboard, as per MARPOL Annex VI.

Marine diesel engine emissions
Marine diesel engines are a significant contributor to national mobile source emission inventories. These engines emit hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), fine particulate matter (PM2.5), sulfur oxides (SOx), and hazardous air pollutants or air toxics. These emissions not only affect populations living near ports and coastlines but also those living hundreds of miles inland. The contribution of marine diesel engines to NOx and PM2.5 emissions is projected to increase in the future.
To address this issue, MARPOL Annex VI was established to regulate air pollution from ocean-going vessels. This annex sets limits on NOx emissions and requires the use of lower-sulfur fuels, reducing ozone-producing pollution and improving air quality in coastal and port areas. The IMO 2020 regulation further decreased the global sulfur limit in marine fuels from 3.5% to 0.5%, outside of Sulfur Emission Control Areas (SECAs). This regulation is expected to prevent a significant number of early deaths and asthma cases annually.
The United States Environmental Protection Agency (EPA) and the United States Coast Guard (USCG) are responsible for enforcing Annex VI through inspections, investigations, and enforcement actions. They also oversee marine fueling facilities and record reviews to ensure compliance. To support these efforts, the EPA introduced a penalty policy for violations of sulfur fuel standards, aiming to deter potential violators and ensure swift resolution.
In addition to Annex VI, other annexes under MARPOL also contribute to the reduction of marine diesel engine emissions. For example, Annex I, which came into force on 2 October 1983, addresses the discharge of oil into the ocean and includes regulations for the treatment of engine room bilge water. Annex IV, which came into force on 27 September 2003, controls pollution from sewage, while Annex V, effective from 31 December 1988, regulates the disposal of garbage and marine debris, with a complete ban on dumping garbage at sea, except for food waste and cargo residues.
Overall, MARPOL plays a crucial role in mitigating marine pollution caused by diesel engine emissions from ships. Through its annexes, particularly Annex VI, and the enforcement efforts of organizations like the EPA and USCG, MARPOL helps to reduce air and water pollution, protect public health, and preserve the marine environment.

The impact of harmful substances
The International Convention for the Prevention of Pollution from Ships, or MARPOL, aims to prevent marine pollution from ships and eliminate pollution from harmful substances discharged from ships. MARPOL has six technical annexes with various chapters and regulations that address different sources of marine pollution.
Annex I: Regulation for Pollution Prevention by Oil
This annex focuses on preventing pollution by oil from operational measures and accidental discharges. The 1992 amendments made it mandatory for new oil tankers to have double hulls, and existing tankers were required to retrofit double hulls. This annex details the discharge criteria and measures for controlling pollution by noxious liquid substances carried in bulk. The discharge of residues is allowed only to reception facilities and must comply with certain concentrations and conditions.
Annex II: Regulations for Controlling Pollution by Noxious Liquid Substances in Bulk
Annex II provides definitions and explains the application of the chapter in various types of ships, such as chemical tankers. It also outlines the need for surveys and certification, with specific regulations for chemical tankers following the International Bulk Chemical Code.
Annex III: Regulation for Preventing Pollution by Harmful Substances Carried at Sea in Packaged Form
This annex defines "harmful substances" as those identified as marine pollutants in the International Maritime Dangerous Goods Code (IMDG Code) or those meeting the criteria in the Appendix of Annex III. It includes general requirements for issuing detailed standards on packing, marking, labelling, documentation, stowage, quantity limitations, exceptions, and notifications.
Annex IV: Regulation for Pollution Prevention by Sewage from Ships
Annex IV came into force in September 2003 and focuses on preventing sewage pollution from ships. It outlines restrictions on the discharge of sewage and provides definitions and applications for different types of ships.
Annex V: Regulation for Pollution Prevention by Garbage from Ships
This annex includes the need for a Garbage Management Plan (GMP), including record books and placards.
Annex VI: Regulation for Prevention of Air Pollution from Ships
Annex VI addresses air pollution from ocean-going ships, establishing limits on nitrogen oxides (NOx) emissions and requiring the use of fuel with lower sulfur content. This helps protect public health and the environment by reducing ozone-producing pollution, such as smog and asthma triggers.
To address these challenges, MARPOL is regularly updated with new regulations, and member states must implement domestic laws to enforce these regulations.
