The IMO Net-zero Framework is the first in the world to combine mandatory emissions limits and GHG pricing across an entire industry sector.
- Shipping accounts for almost 3% of global greenhouse gas emissions.
Key Features
- It will be included in Annex VI (Prevention of air pollution from ships) to the International Convention for the Prevention of Pollution from Ships (MARPOL).
- Aim: Net-zero emissions by or around, i.e. close to 2050.
- Ships will be required to comply with:
- Global Fuel Standard: Ships must reduce, over time, their annual greenhouse gas fuel intensity (GFI) – that is, how much GHG is emitted for each unit of energy used.
- Global Economic Measure: Ships emitting above GFI thresholds will have to acquire remedial units to balance its deficit emissions, while those using zero or near-zero GHG technologies will be eligible for financial rewards.
- IMO Net-Zero Fund: It will be established to collect pricing contributions from emissions.
- Implementation: Set to be formally adopted in October 2025 before entry into force in 2027.
- Once into force, it will become mandatory for large ocean-going ships over 5,000 gross tonnage, which emit 85% of the total CO2 emissions from international shipping.
