The Costly Bill of Maritime Transport Decarbonization

Reducing Pollution and Preserving the Planet: A Costly Endeavor for the Maritime Industry

The consensus is clear: reducing pollution and preserving the planet requires massive investments. Recently, the maritime transport sector has expressed its concerns about the ambitious goals set to achieve carbon neutrality. A group of shipowners, representing over 1,200 vessels, has warned that the carbon neutrality rules planned by the International Maritime Organization (IMO) for 2050 could impose significant costs on the industry. The IMO is set to officially adopt a plan in October 2025, which would require ships to pay fees on at least part of their emissions. The sector could face annual costs of between $20 and $30 billion by 2030, potentially exceeding $300 billion by 2035 if the global fleet misses its targets by even 10%. This would not effectively decarbonize the maritime sector and would not ensure fair competition conditions.

A Global Effort

Despite opposition from the United States, the majority of countries have supported the proposal in an earlier IMO vote. The International Chamber of Shipping, which represents over 80% of the global merchant fleet, also backs the plan. However, the question remains: is our national fleet ready for this additional burden? The transport sector is already fragile, and this would add to its challenges. In Tunisia, transport is the second-largest carbon emitter, accounting for 24% of emissions, with a notable contribution from maritime transport. This is a factor that should not be neglected.

Key Statistics:

  • 1,200+ vessels represented by the group of shipowners
  • $20-30 billion: potential annual costs for the sector by 2030
  • $300 billion: potential costs by 2035 if targets are missed by 10%
  • 24%: contribution of transport to carbon emissions in Tunisia
  • 80%: percentage of the global merchant fleet represented by the International Chamber of Shipping

Conclusion

The maritime industry is facing significant challenges in reducing its carbon footprint. While the IMO's plan aims to promote sustainability, it is crucial to consider the potential costs and ensure that the measures implemented are effective and fair for all stakeholders involved.
