Cruise ships capable of accommodating more than 100 passengers in Sydney Harbour are required to limit emissions of sulphur oxides when berthing (maximum 0.10% m/m). It is like a mini-ECA in Sidney waters. Learn more here.

For ships operating outside Emission Control Areas (ECAs), the limit for sulphur content of fuel oil is 0.50% m/m (mass by mass). Learn more about the global sulphur limit for shipping here.

The Ship Energy Efficiency Management Plan II (SEEMP II) is the updated version of the first SEEMP. It includes to obligation of vessels of 5000 GT and above to input CO2 data into the IMO Data Collection System (DCS). Learn more about SEEMP II and how it impacts your vessel’s operations here.

The IMO Data Collection System (DCS) is the reporting system for IMO that collects data as part of SEEMP II. Ships above 5000 GT are required to yearly input aggregated data to flag state. Impact on operations is limited. Learn more about IMO DCS here.

The Ship Energy Efficiency Management Procedure (SEEMP) is a - not too stringent - IMO mandated plan to increase energy efficiency and reduce emissions. Learn more about SEEMP and how it impacts your vessel’s operations here.

The Carbon Intensity Indicator (CII) is a rating to determine carbon intensity of your vessel by IMO. It is part of SEEMP III and mandates a reduction of 11% by 2026 and 70% by 2050. Learn more about CII and how it affects your vessel’s operations here.
