Prévisions concernant le transport maritime Septembre 2024

Carbon Market Watch (CMW) assessed several market-based measure (MBM) proposals for the international shipping sector, using a methodology developed by CE Delft. The evaluation focused on alignment with the Paris Agreement's 1.5°C goal, immediate emission reductions, support for vulnerable nations and workers, and funding for research and development. The analysis highlights that current IMO strategies are insufficient for 1.5°C alignment and that only proposals with high carbon levies—such as those from Canada and Austria et al.—provide a strong enough price signal to drive the transition to zero-emission technologies.

• International shipping accounts for approximately 3% of global greenhouse gas (GHG) emissions, a figure that could rise by 50% by 2050 without intervention. While the IMO's 2023 strategy targets net-zero GHG emissions by or around 2050, including reductions of 20-30% by 2030 and 70-80% by 2040 relative to 2008 levels, these actions are deemed insufficient to align with the Paris Agreement's 1.5°C limit.
• The proposal by the Bahamas et al., which combines a GHG fuel standard (GFS) with a flexibility compliance mechanism (FCM) allowing the purchase of 'remedial units', is not considered a viable economic measure. It is argued that this system discourages decarbonization by only covering emissions from ships that exceed the required GHG intensity, resulting in insufficient revenue to support a just transition.
• The proposal from Angola et al. is noted for its strong focus on immediate emission reductions and support for Least Developed Countries (LDCs) and Small Island Developing States (SIDS), but it is criticized for a low carbon price (18.75 $/tCO2e), a vague timeline, and a lack of detail regarding long-term goals and R&D funding.
• Canada and Austria et al. (EU/Japan) are identified as having the most ambitious proposals, with Canada proposing a tax of 150 $/tCO2e and Austria et al. proposing 130 $/tCO2e. These higher levies are seen as necessary to encourage the shift to zero-emission technologies and generate sufficient funds for infrastructure and research.
