The Panama Canal Authority is pleased to announce the launch of the NetZero Slot, a dedicated low
carbon transit slot designed to support and reward our clients on their journey toward decarbonization
and net-zero greenhouse gas emissions by 2050.
Starting on October 5, 2025, one NetZero Slot will be available weekly at the opening of Period 1A for
Neopanamax vessels. The winner of this slot will benefit from:
- Choice of transit date within the offered week
- Guaranteed 24-hour in-transit time
- Included Just-In-Time (JIT) service
Participation Requirements:
To be eligible, vessels must meet specific low-carbon criteria that will evolve over time in alignment with
the industry’s path toward net-zero by 2050, while considering regional infrastructure availability and the
characteristics of transiting vessels.
Phase 1: Recognizing Investments in Greener Vessels, October 2025
Vessels must be dual fuel ready and capable of operating with at least one fuel with a well-to wake (WtW) carbon intensity lower than 75 gCO2(e)/MJ.
The table in the advisory provides a carbon intensity matrix for common marine fuels. The carbon intensity is expressed in grams of CO2(e) per megajoule of energy produced (gCO2/MJ). Biofuels are evaluated based on the percentage of biofuel content in the blend. The values in the preceding table are aligned with FuelEU Maritime and are expected to vary depending on feed stock and production method. The actual Carbon Intensity factor shall be obtained from the fuel supplier certificate.
Phase 2: Encouraging Energy Efficiency Investments, 2026
In addition to Phase 1 requirements, vessels must submit a Technology Screening Report, which
evaluates energy efficiency technologies applicable to the vessel.
The report’s specifications, the list of approved third-party verifiers and the specific start date for Phase 2 will be provided in advance through an Advisory to Shipping.
Selection Process:
The NetZero Slot will be allocated through a competition based on the following characteristics:
- Cargo Condition – Laden vessels will be given priority.
• Capacity – Vessels with a larger Panama Canal Universal Measurement System (PCUMS) capacity
will have priority.
A Step Towards a Sustainable Future:
The NetZero Slot is part of the Panama Canal Authority’s commitment to reward and incentivize
investments in energy efficiency and low-carbon fuels. As the shipping industry progresses toward net
zero emissions, we will continuously update the eligibility criteria to recognize and support these efforts.
Further updates regarding this matter will be communicated through Advisories to Shipping.
