A Historic Moment for Global Shipping

In what could become a game-changing moment for international trade and environmental policy, the United Nations' shipping agency, the International Maritime Organization (IMO), is edging closer to implementing the world’s first global carbon tax on international shipping. The proposal, under discussion at the IMO’s Marine Environment Protection Committee (MEPC) this week in London, could introduce legally binding regulations to phase out fossil fuels across the industry — a sector responsible for transporting roughly 90% of the world's traded goods and generating about 3% of global CO₂ emissions.

What’s on the Table? Fuel Standards & Carbon Pricing

The IMO’s negotiations center on a multi-pronged strategy to decarbonize the maritime sector. Key proposals include:

• A Global Marine Fuel Standard to limit the carbon intensity of shipping fuels.
• A Carbon Pricing Mechanism, either through a direct tax or a market-based carbon credit scheme.

These policies aim to push the shipping industry toward adopting zero and near-zero carbon fuels like green ammonia, methanol, and hydrogen-based technologies. The stakes are high: a robust carbon pricing mechanism could become one of the most significant climate action agreements of the decade.

Not Everyone Is on Board

Despite momentum, reaching a consensus is proving difficult. Countries like Brazil, China, and Saudi Arabia have voiced strong opposition to carbon levies, citing concerns about competitiveness and economic disparity. On the other hand, island nations most vulnerable to climate change — such as Fiji, the Marshall Islands, Vanuatu, Jamaica, and Barbados — are some of the strongest advocates for urgent action.

“This is a once-in-a-generation opportunity,” said Ralph Regenvanu, Vanuatu's Minister of Climate Change. “The UN climate framework hasn’t moved fast enough. This initiative through the IMO could deliver real, enforceable progress.”

If adopted, this would be the first time a UN agency mandates a sector-wide carbon reduction with such strong enforcement potential, surpassing what has so far been achieved under the UNFCCC (United Nations Framework Convention on Climate Change).

Financial Impact: How Much Will It Cost?

Current proposals suggest a carbon levy in the range of $100 to $150 per tonne of CO₂ emitted. According to the World Bank, this could raise tens of billions of dollars annually, which could then be redistributed to support:

• Developing nations and vulnerable economies
• Green innovation in shipping
• Infrastructure for alternative fuel production

Critics fear such costs could be passed down the supply chain, leading to higher shipping costs and potential trade disruptions. But advocates argue that the revenue could accelerate the transition to clean shipping technologies while delivering climate justice.

Voices from Industry and Advocacy

Sara Edmonson, head of global advocacy at Fortescue, called the negotiations “absolutely historic,” emphasizing that no other industry has made such a globally unified attempt to decarbonize.

“This would be a global-first, a levy structure that could genuinely change the trajectory of shipping emissions,” she said. “Of course, terms like ‘levy’ are politically sensitive in the U.S., Australia, and China, but similar structures could be adopted with the same effect.”

John Maggs, President of the Clean Shipping Coalition, echoed the optimism but remained realistic. “We will get something. The timeline is tight, and negotiations are intense. But the question is: How ambitious will it be?”

Why Shipping Is So Hard to Decarbonize

Unlike road transport or aviation, shipping involves massive vessels crossing thousands of kilometers, often outside the jurisdiction of any single nation. Most ships still run on heavy fuel oil, a high-emission, sulfur-rich byproduct of crude oil processing.

Switching to cleaner alternatives requires not only fuel innovation but also global port infrastructure, crew retraining, and regulation synchronization across 175 IMO member states.

According to the International Energy Agency (IEA), the industry must reduce its emissions by at least 45% by 2030 and reach net zero by 2050 to align with the Paris Agreement targets.

What’s Next?

The MEPC is expected to finalize its “mid-term measures” package by spring 2025, with implementation potentially starting as early as 2027. These measures are crucial to hitting the IMO’s 2023 pledge of achieving net-zero emissions “by or around 2050.”

Environmental groups, including the Environmental Defense Fund (EDF), are pushing for:

• A firm implementation timeline
• A fair disbursement mechanism
• Incentives for early adopters of clean technology

“Ambitious outcomes must be backed by funding structures that support climate-vulnerable nations and help the shipping sector transition at scale,” said Angie Farrag-Thibault, EDF’s Vice President for Global Transport.

Final Thoughts

The clock is ticking. As global temperatures climb and international trade continues to grow, the decisions made at this week’s IMO meeting could shape the future of both climate policy and global commerce.

If adopted, the carbon levy would not only be a first for shipping — it would be a bold precedent for other high-emission industries to follow.
