The Superyacht Eco Association SEA Index has partnered with the Japan Marina & Beach Association (JMBA), adding 87 marinas to the organisation.
The partnership marks its first alliance in the Asia‑Pacific region.
SEA Index was founded by the Yacht Club de Monaco in partnership with Credit Suisse to provide an independent tool to assess and compare the environmental impact of yachts.
Prior to this partnership agreement, SEA Index comprised 25 major superyacht ports and marinas across multiple countries.
The network now aims to further share verifiable standards and transparent data to accelerate the adoption of better environmental practices in yachting.
Environmental awareness initiatives
JMBA was established more than 50 years’ ago and consists of a nationwide network of marinas and coastal facilities.
As an Institutional Member, JMBA will actively promote SEA Index certification across its marina network, including environmental awareness initiatives and the gradual integration of sustainability‑linked incentives.
“Until now, Japanese marinas and yachting culture have developed primarily as places to enjoy the sea,” said Kiichiro Kumazawa, president of KMC Corporation and JMBA president.
“Today, however, we are being called upon to move to the next stage — one that asks how we can coexist with the sea.
“The clear and internationally shareable benchmarks presented by the SEA Index are an essential tool that moves environmental consideration beyond philosophy and into practical action.”
Clarity and credibility
Bernard d’Alessandri, president of SEA Index and secretary general of the Yacht Club de Monaco, added: “SEA Index was conceived as a practical tool to bring clarity and credibility to environmental performance in yachting.
“Welcoming the Japan Marina & Beach Association into our network confirms that this approach resonates far beyond Monaco and the Mediterranean. What matters is not where a yacht sails, but how responsibly it does so.
“This partnership demonstrates that shared metrics can unite very different maritime cultures around the same objective: measurable progress.”
