SEA Index® & RINA Give Superyacht Owners Power to Track Operational CO2 Emissions.

Monaco, july 08, 2024

Spotlighting operational aspects and total life-cycle transparency, the SEA Index – (Superyacht Eco Association by Yacht Club de Monaco) and RINA have been working closely together to develop a new operational efficiency assessment method that evaluates the direct emissions of yachts over 25m and 400 Gross Tons based on choice of fuel.

A total life cycle approach of the fuel used is applied, this means a well -to- wake methodology* of calculating emissions intensity. The newly unveiled fuel consumption method can also calculate the emissions in case biofuels are used, such as HVO (Hydro Treated Vegetable Oil), even if they are blended with conventional fuels.

Employing a well-to-wake methodology, the method calculates emissions intensity throughout the entire life cycle of the fuel used, based on international standards approach. This holistic perspective allows stakeholders to make the right decisions and implement targeted strategies for reducing environmental footprint.

The Index considers the same principles of the GHG (Greenhouse gas) Strategies adopted by the International Maritime Organization and the European Union.

RINA Marine Technical Director, South-West Europe Region, Giuseppe Zagaria comments:

“We are very satisfied collaborating with Sea Index and we appreciate their activities toward a greener yachting. We have a very long history of cooperation with the whole yachting cluster in Monaco to which we would like to affirm the RINA experience for environmental protection. We compliment the commitment of Mr. Bernard D’Alessandri and Natalie Quevert expanding the Sea Index initiatives towards the yachting operational efficiency aspect, a key pillar of any decarbonization strategy.”

SEA Index project manager, Natalie Quévert further comments: “Collaborating with RINA is enabling the Superyacht Eco Association to expand the scope of available tools for Owners, Captains and other stakeholders allowing them to assess impact depending on their choice of yacht fuel. The well- to- wake approach ensures the method is future proof and we commend RINA and Giuseppe Zagaria for this valuable contribution to the SEA Index under the aegis of the ‘Monaco Capital of Advanced Yachting’ collective approach initiated by the Yacht Club de Monaco (YCM).”

*Well -to -wake methodology: Well-to-wake emissions analysis is also known as life cycle analysis. It includes emissions related to every stage in the life cycle of a fuel — from its production until it is used to fuel a vessel.

Evolutions of the SEA Index® over time:

September 2020 – Launch of the SEA Index®

September 2021 – Launch of phase II of the SEA Index®

The opportunity to present “Friends of the SEA Index®”, a new category of members of the Superyacht Eco Association, open to natural and legal persons who do not own a yacht assessed by the SEA Index®, but which nevertheless adhere to the principles and values of the Superyacht Eco Association.

July 2023 – Launch of phase III of the SEA Index®

Phase III marks an important step, as it expands the range of yachts already covered by the calculation tool (40m+). Now a wider range of vessels, including those up to 25 meters in length, can benefit from this comprehensive and unbiased energy intensity assessment tool.

September 2023 – Launch of phase IV of the SEA Index®

Launched in Cannes in collaboration with Azimut Yachts, phase IV assesses the energy intensity of yachts from 8 to 24 meters based on their fuel consumption.
