Panama Canal Introduces “NetZero Slot” To Promote Low-Carbon Shipping

The Panama Canal has announced the launch of a NetZero Slot, a dedicated transit slot for vessels with low-carbon emissions to achieve net zero emissions by 2050

It aims to encourage shipping companies to choose cleaner fuels and energy-efficient technologies.

According to Advisory to Shipping No. A-07-2025, the NetZero Slot will be introduced in phases, starting October 5, 2025, with a weekly slot available for Neopanamax vessels that meet strict low-emission criteria.

Instead of being auctioned, this slot will be awarded through a competition in Period 1A, help 30 days before the transit date.

Vessels must be equipped with dual-fuel engines that operate on fuel with a carbon intensity of less than 75 gCO2(e)/MJ, measured from extraction to combustion (Well to Wake or WtW).

The second phase of this initiative, planned for 2026, will have more specifications, which will be announced in a future advisory.

Ships that secure the NetZero Slot will receive several advantages, including:

• The ability to select a transit date within the allocated week.
• A guaranteed transit time of 24 hours to improve operational efficiency
• Just-in-Time (JIT) service to minimise delays and optimise scheduling.

The canal’s Deputy Administrator and Sustainability Officer stated that this initiative will support global maritime efficiency while reducing environmental impact.

She highlighted that by encouraging investment in low-carbon vessels, the canal is rewarding shipping companies that actively contribute to decarbonisation efforts.
