The International Maritime Organization (IMO) has taken a historic step by approving a draft global framework aimed at achieving sustainable maritime transport with net-zero emissions by 2050.
The agreement, set to be formally adopted in October 2025, introduces binding international regulations to cut greenhouse gas (GHG) emissions from ships.
This marks the first worldwide deal that combines mandatory emission limits with a sector-wide carbon pricing mechanism.
Ships using low- or zero-emission fuels will be eligible for economic incentives, while those exceeding emission limits will face financial penalties.

New rules to apply from 2027 to large vessels
Starting in 2027, the new rules will be mandatory for vessels over 5,000 gross tons, which account for 85% of international maritime CO₂ emissions.
The IMO aims to accelerate the shift toward low-emission fuels and technologies through this initiative.
“This approval highlights our collective commitment to combat climate change and modernize maritime transport,” said IMO Secretary-General Arsenio Dominguez.
Net-Zero Fund to support innovation and equity
A key element of the new framework is the Net-Zero Fund, which will collect carbon fees and invest in research, innovation, infrastructure, and technology transfer.
Ships with lower GHG emissions will benefit from financial rewards, while those exceeding the thresholds must compensate through contributions to the fund.
The fund will also support training and capacity-building in developing countries, aligning with the 2023 IMO Strategy and promoting a just and equitable transition in the maritime sector.
