Historic First: Shipping Nations Agree to Global Carbon Pricing

On April 11, 2025, the world’s major maritime nations agreed to a groundbreaking measure:
a global emissions fee for greenhouse gases from ships, under the International Maritime Organization (IMO).

This marks the first-ever international carbon pricing mechanism for the shipping industry, which is responsible for nearly 3% of global emissions.

What’s in the Plan?

1. Global Emissions Fee (2027 Start)

Ships exceeding emission thresholds will pay at least $100 per ton of CO₂-equivalent.

Implementation begins in 2027 and targets both CO₂ and methane emissions.

2. Estimated Revenue: $13 Billion per Year

Funds will support:

Cleaner fuel technology

Rewards for low-emission vessels

Sustainability aid for developing nations

3. Marine Fuel Standard Set

A global fuel emissions standard will be introduced to push for net-zero emissions by 2050.

Mixed Reactions

Environmentalists: Some call it a bold first step, others say it’s too easy to “pay to pollute.”

U.S. Abstention: The United States did not participate in the vote, citing economic impacts.

Developing Nations: Pushing for faster, more ambitious climate action.

>“Shipping is finally charting a course toward climate accountability.”

What’s Next?

The agreement will be formally adopted in October 2025.

The maritime sector now joins aviation and land-based industry in applying market-based tools to fight climate change.

Mare’s View

The days of unregulated maritime emissions may be ending.
This global fee could become a model for future climate diplomacy at sea.
