Panama Canal Launches NetZero Slot To Advance Maritime Decarbonisation

The Panama Canal has announced the launch of the NetZero Slot, a new category within its transit reservation system designed to encourage the decarbonisation of maritime shipping and to support the canal’s institutional commitment to achieving net-zero emissions by 2050.

The first competition to allocate this slot will take place on October 3, 2025, applicable to the transit week of November 2–8, 2025. Beginning on that date, one weekly slot will be reserved exclusively for vessels that meet low-emission criteria.

Benefits for clients awarded the NetZero Slot include:
• Freedom to select their preferred transit date within the assigned week.
• Guaranteed transit within 24 hours.
• Inclusion of the Just-in-Time service.
• Flexibility to exchange, or substitute vessels of equivalent specifications.

Participation Requirements:

In this initial phase, vessels must be registered as dual-fuel and capable of operating on at least one fuel with a carbon intensity factor equal to, or less than 75 gCO₂e/MJ. Eligible fuels include green methanol, green ammonia, bio-LNG (Liquified Natural Gas), or bio-LPG (Liquified Petroleum Gas). While immediate use of these fuels will not be required, the canal will recognise the investment and capacity to operate them once supply becomes available.

Selection Process:

The NetZero Slot will not be auctioned. Instead, vessels will compete weekly under a prioritization scheme based on:
1. Cargo Condition: Preference given to loaded vessels.
2. PCUMS Capacity: Priority awarded to higher tonnage.
3. Economic Contribution: Combined payments from tolls, maritime services, and fees from prior transit (used as a tiebreaker).

With this initiative, the Panama Canal reaffirms its role as a catalyst of the global energy transition, offering customers a clear incentive to accelerate the adoption of alternative fuels and low-carbon technologies.

“The NetZero Slot is an unequivocal signal of our commitment to sustainability and the competitiveness of global trade. Through this initiative, we aim to support our customers in the transition toward a low-emissions future,” said Ilya Espino de Marotta, Deputy Administrator and Chief Sustainability Officer.
