Superyacht Eco Association

SEA Index ®

Under the aegis of the ‘Monaco Capital of Yachting’ initiative, led by the Principality of Monaco, the Superyacht Eco Association is a non-profit organisation, founded by the Yacht Club de Monaco and Credit Suisse.

The scope of the Superyacht Eco Association (SEA), is to increase the yachting industry’s awareness of its carbon impact on the environment and to strengthen the commitment of the Principality of Monaco as a center of excellence, innovation and environmental leadership in the field of yachting.

The SEA strives to mobilise all industry stakeholders, private and corporate, in Monaco and internationally, towards reducing superyacht carbon emissions. Our initiative comes in response to strong demand from superyacht owners, keen to assess their impact and support the industry as it moves forward towards a climate-friendlier future.

An increasing number of superyacht owners are already adopting a sustainable approach as a matter of personal choice and are aiming for the highest standards. They are the ones driving change by soliciting shipyards and financing the research and development associated with their projects.

“The next decade will be a decisive one for the future of our planet. Climate change is one of our biggest challenges.”

Our Vision

Our vision is that the SEA Index tool will become the global industry standard.
By providing transparency, the label allows all stakeholders to easily assess a yacht’s carbon impact.

In turn, this will enable the industry to generate new products based on their carbon rating and create incentives for builders and owners to design yachts with lower fuel consumption and less environmental impact.

Our Mission

Our mission is to be an aggregator, bringing together shipyards, operators and yacht owners. We aim to support key industry players towards change and define objectives to reduce emissions, on a voluntary basis, provide information and help implement new solutions.

The long-term goal of the SEA INDEX is to become the world’s leading air pollution rating system for superyachts, which can also be extended to other sectors and thus lead to a multifaceted sustainability index.
