Émissions atmosphériques - NOx

Monitoring of regulations

The use of specialized software or other verifiable procedure can serve as evidence that the practices below have been implemented.

2.1 Implement a systematic control policy for documenting fuel (e.g. Bunker Delivery Notes (BDN), best practices application, or any other proof of the control policy in place). BDN should refer to IS0 8217:2017 tables at least.

Note: BDN must be retained, and annual consumption notes must be kept for each ship.

2.2 Plan voyages and stopovers with using decision tools based for example on climatology and weather forecasting to reduce/optimise energy used for each voyage.

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

2.4 Implement a preventive engine maintenance system to optimize performance.

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

2.6 Implement a program for energy efficiency upgrades (e.g., lighting, heating/cooling).

2.7 Conduct an internal survey for equipment or energy loads that could be more efficient with smart controls, variable loads, or other means, i.e. HVAC in unoccupied spaces, air compressor, or cooling pump; and/or from survey findings, make progress right-sizing or upgrading equipment, balancing loads, or similar.

Pilot Boats and Tugs Only:

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

3.1. Complete an annual inventory of NOx emissions for all the company's ships.

Note: See Annexes 2-C and 2-D.

4.1. Conduct sampling of NOx emissions on at least one of the company’s ships within the last 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 IMO NOx Technical Code 2008.

4.2. On board one or more of the company's owned ships, install a higher tier engine than required or use and maintain on-engine or after-treatment NOx emission reduction technologies, like selective catalytic reduction (SCR) or exhaust gas recirculation (EGR), or methods that result in a 15% reduction of NOx emissions below the permitted limits.

Note: Permitted limits are published in the document ‘NOx emission permitted limits’ in the Members section of the Green Marine Europe website.

Fulfill one of the following 2 criteria:

5.1. On board the majority (50%+1 representing at least 30% of the gross tonnage) of the company's owned ships, install a higher tier engine than required or use and maintain on-engine or after-treatment NOX emission reduction technologies or methods that result in a 15 % reduction of NOX emissions per ship below the permitted limits.

Note: Permitted limits are published in the document ‘NOx emission permitted limits’ in the Members section of the Green Marine Europe website.
Note: Under the designation of these NECAs, marine diesel engines installed on board ships built on or after 1 January 2021 and operating in the North Sea and Baltic Sea should comply with the Tier III NOx emission limits

OR

5.2. On board one or more of the company's owned ships, achieve a 50% or greater reduction of NOX emissions per ship below the permitted limits by installing a higher tier engine than required or by using and maintaining NOX emission reduction technologies.
