Polluant air emissions SOX & PM

Performance indicator's objective:

Reduce pollutant air emissions of sulphur oxides (SOx) and particulate matter (PM).

2022 criteria

Level 1

Monitoring of regulations

Level 2

2.1. Implement a systematic control policy for documenting fuel (bunker notes).

Note: Bunker notes must be conserved, and annual consumption notes must be kept for each ship.

2.2. Use climatology and weather forecasting to take advantage of tidal currents and avoid storms. Plan voyages to reduce running hours and idling time.

2.3. Optimize trim for fuel efficiency when loading ships and barges.

2.4. Follow voluntary slow speed measures in specific zones, as identified by port or governmental authority.

Note: the identified zones are Particularly Sensitive Sea Areas (PSSA): http://www.imo.org/en/OurWork/Environment/PSSAs/Pages/Default.aspx

2.5. Implement a preventive engine maintenance system in order to optimize performance.

2.6. Identify optimal engine speed or engine load for fuel efficiency. Inform crew and ensure awareness of this optimal ‘economic’ speed or engine load. Transit at this speed or load to the extent practicable.

2.7. Implement a replacement program for LED or other energy efficiency light upgrades.

Tugs Only:

2.8. Reduce tug idling with dispatch scheduling and/or provide tie-up locations where awaiting tow or escort.

Level 3

3.1. Complete an annual inventory of SOx and particulate matter (PM) emissions for all the company's ships.

Note: See Annexes 2-A, 2-B, and 2-D.

3.2. The average sulphur content by mass of the total amount of fuel consumed annually by all of the company’s vessels is less than 0.45%.

Note: Fuel sulphur limit is 0.1 % within an ECA and 0.5 % outside ECAs.

Note: ship owners can use equipment or alternative fuel allowing for the attainment of the same level of sulphur emissions as above.

Fulfill one of the following two criteria:

3.3. Reduce SOx emissions in berth by using alternatives to traditional marine fossil fuel, i.e. cold ironing (if available at docks), LNG, Biogas, Biofuel, H2, fuel cell, batteries, wind or solar energy as an auxiliary energy, or EGCS. Those measures should be implemented on at least 10% of the fleet (representing 7% or more of the tonnage).

OR

3.4 Reduce SOx in Port/Berth by using a fuel with sulphur content equal to less than 0,1%, including for every call, including short calls (less than 2 hours) on 100% of the fleet

Note: ship owners can use equipment or alternative fuel allowing for the attainment of the same level of sulphur emissions as above.

Level 4

4.1. The average sulphur content by mass of the total amount of fuel consumed annually by all of the company’s vessels is less than 0.35%.

Note: Fuel sulphur limit is 0.1 % within an ECA and 0.5 % outside ECAs.

Note: ship owners can use equipment or alternative fuel allowing for the attainment of the same level of sulphur emissions as above.

4.2. Reduce SOx emissions in berth by using alternatives to traditional marine fossil fuel, i.e. cold ironing (if available at docks), LNG, Biogas, Biofuel, H2, fuel cell, batteries, wind or solar energy as an auxiliary energy, or EGCS. Those measures should be implemented on at least 25% of the fleet (representing 15% or more of the tonnage).

AND (all ship owners), fulfill one of the following 2 criteria:

4.3. Sample PM emissions for one of the fleet's main engine types (slow-speed, medium-speed, high-speed, gas or steam turbine).

Note: Sampling must be repeated every five (5) years. The sampling test plan must be consistent within the fleet, comparable with prior tests, and a recognized methodology, such as ISO 8178 or 40 CFR 51 Appendix M and 40 CFR 60 Appendix A.

OR

4.4. Actively participate in research and development on reducing the impact of SOx and PM emissions, for example – improving inventory tools, developing hybrid or blended fuels, or conducting a pilot project on emission reduction technologies.

Note: Active participation is defined as the provision of support by the company, whether through financial means, human resources or equipment and can include an experimental shipboard trial.

Level 5

5.1. The average sulphur content by mass of the total amount of fuel consumed annually by all of the company’s vessels is less than 0.25%.

Note: Fuel sulphur limit is 0.1 % within an ECA and 0.5 % outside ECAs.

Note: ship owners can use equipment or alternative fuel allowing for the attainment of the same level of sulphur emissions as above.

5.2. Reduce SOx emissions in berth by using alternatives to traditional marine fossil fuel, i.e. cold-ironing (if available at docks), LNG, Biogas, Biofuel, H2, fuel cell, batteries, wind or solar energy as an auxiliary energy, or only closed-loop EGCS. Those measures should be implemented on at least 50%+1 of the fleet (representing 30% or more of the tonnage).

5.3. On board one or more of the company's owned ships, compared to no treatment, achieve a 75 % or greater reduction of PM emissions per ship by (i) applying pre-treatment and on-engine measures, (ii) applying after-treatment measures, such as a diesel particulate filter (DPF), diesel oxidation catalysts (DOCs), or other exhaust gas cleaning system (EGCS), (iii) using wind propulsion, or by (iv) using LNG or other energy-solutions having low Sox & PM emissions.

5.4. In the polar zone, vessels will not use or carry any heavy fuel or VLSFO/ULSFO.
