Efforts are underway for a groundbreaking global agreement to impose a fee on commercial vessels for their emissions, potentially establishing the world’s first international carbon tax. The International Maritime Organization (IMO), responsible for regulating international shipping, has set a goal for the industry to achieve net-zero greenhouse gas emissions by approximately 2050.
It is committed to promoting the use of fuels with zero or near-zero emissions more extensively. This week, the IMO’s Marine Environment Protection Committee is convening in London to discuss and potentially approve new global regulations aimed at pricing maritime greenhouse gas emissions and setting standards for cleaner marine fuels.
The committee, comprising member states of the IMO, seeks to make these regulations mandatory for all ships operating worldwide. The IMO Secretary-General, Arsenio Dominguez, emphasized the necessity for the industry to intensify efforts to reduce carbon pollution, stating that these measures will set a course toward a net-zero future for the maritime sector.
Emma Fenton from the climate change nonprofit Opportunity Green highlighted the significance of adopting a high, flat-rate levy on shipping emissions as a crucial step in decarbonizing the industry equitably. Achieving such an agreement would mark a significant moment of global unity in addressing climate change, offering a comprehensive framework for tackling this international challenge.

Understanding the Talks
Emissions from the shipping industry have escalated over the past decade, now accounting for approximately 3% of global emissions, as reported by the United Nations. This increase is attributed to larger vessels transporting more cargo and consuming significant quantities of fuel oil. Maritime nations committed in 2023 to reduce emissions from the shipping sector, but some experts criticized the agreement for not establishing 2050 as a definitive deadline. The IMO is currently working on regulations to meet the 2023 goals.
Global Significance of the Agreement
A straightforward climate levy, coupled with a green fuel standard, could help bridge the cost gap between fossil fuels and environmentally friendly alternatives like hydrogen, methanol, and ammonia. Jesse Fahnestock of the Global Maritime Forum pointed out that the shipping industry heavily relies on fossil fuels and will not transition independently. Developing a supply of e-fuels based on renewable electricity will require investments now. Currently, most ships run on heavy fuel oil, releasing carbon dioxide and other pollutants during combustion. Decarbonizing shipping fuels necessitates significant changes, as highlighted by Dominguez.
Current Status of Negotiations
Over 60 countries, led by Pacific island nations facing existential threats from climate change, advocate for a uniform levy per metric ton of emissions to achieve net-zero emissions fairly.
The shipping industry, represented by the International Chamber of Shipping, which covers over 80% of the world’s merchant fleet, also supports a pricing mechanism for maritime emissions as a pragmatic solution to expedite energy transition. However, some countries, such as China, Brazil, Saudi Arabia, and South Africa, prefer a credit trading model instead of a fixed levy. This model would allow ships to earn credits for staying within emissions targets and purchase credits if they exceed limits.
Concerns exist that anything less than a universal levy could undermine climate goals, allowing wealthier ship owners to buy compliance while continuing to pollute.
Ambassador Albon Ishoda from the Marshall Islands suggested that without the levy, the IMO’s climate targets are “meaningless.” Revenue generated from a levy could support developing countries in transitioning to greener shipping practices, preventing them from being left with outdated fuels and vessels.
Anticipated Outcomes
If the committee reaches an agreement and finalizes the regulations’ text, formal adoption could occur by October, with implementation starting in 2027. This would signal a robust commitment to a green transition in the shipping industry, demonstrating the possibility of global cooperation in this sector, according to the IMO.
The Evolving Landscape
- A successful agreement could lead to cleaner fuel use in the shipping industry, reducing environmental pollution and promoting sustainable practices.
- Introducing a global carbon tax on shipping emissions may influence global trade costs, affecting consumer prices and international commerce.
- Developing countries could benefit from the levy revenues to advance their transition to greener shipping technologies and infrastructures.
- The agreement may set a precedent for other sectors to adopt similar strategies for reducing greenhouse gas emissions, prompting broader environmental initiatives.
- Consumers might see changes in the availability and pricing of goods, as the shipping industry adapts to new regulations and fuel standards.
