“We have been collaborating with Y.CO’s technical and sustainability teams for over a year and this official announcement is consistent with our shared views on where the yachting sector’s focus and leadership is most needed”, added Natalie Quévert, General Secretary of SEA Index® Superyacht Eco Association.
An initiative of the Yacht Club de Monaco, SEA Index has become the reference point for CO₂ transparency in the superyacht sector, providing third-party verified assessments that enable better decision-making. With the association now expanding its scope to explore additional environmental impact indicators, Y.CO’s corporate membership reflects a proactive stance—one that aligns with the shifting expectations of clients, charterers, and the broader industry.

About SEA Index
Launched in 2020 by the Yacht Club de Monaco, under the aegis of its ‘Monaco, Capital of Advanced Yachting’ initiative, the Superyacht Eco Association (SEA Index) is a non-profit organisation designed to minimise the impact of yachting in order to preserve the oceans for future generations.
By enabling yachting stakeholders to accurately measure and reduce their environmental impact via a range of unbiased tools, methodologies and indices, SEA Index empowers the yachting community and increases transparency throughout the sector.
SEA Index’s flagship CO2 certification program is based on the International Maritime Organisation’s EEDI and EEXI and is adapted for yachts 24m+. The only superyacht design index to offer third-party verification, certificate holders that achieve 3-stars or higher on the SEA Index are invited to join the SEA Index network, which provides access to exclusive benefits, including priority berthing at selected ports and marinas.
