It is our vision that the SEA Index will become the global industry standard. By providing transparency, the label will allow all stakeholders in the industry to easily assess a yacht’s ecological standards. This will in turn enable the industry to generate new products based on their environmental rating and create incentives for both builders and owners to design and build yachts with lower fuel consumption and less environmental impact.

The initiative comes in response to strong demand from owners, who are keen to calculate their impact and support the industry as it moves towards a climate-friendlier future. An increasing number of owners are already adopting a sustainable approach as matter of personal choice and aiming for the highest standards. They are driving change by soliciting shipyards and financing the research and development associated with their projects.

We started from the observation that to date, there has been no reference point for the yachting industry. As a collective voice of the industry, the Association has set out to calculate benchmarks and define measurable objectives. Our SMART approach ensures that the index is designed to be specific, measurable, achievable, relevant and time-based.

By calculating the real impact of each vessel, we hope not only to increase awareness, but also to drive owners and shipyards to continue to explore solutions that will make a difference by reducing the pollution levels and environmental impact – starting with CO2 and fine particle emissions. Once the reference framework is established, we can set specific emission-reduction targets.

Our ultimate goal is the reduction of emission levels even with a growing fleet of yachts. Although the yachting industry accounts for a very small percentage of pollution, every improvement is beneficial to the planet and the ocean.

Most existing measurements only cover commercial ships, which gives the SEA Index the opportunity to fill the gap in the superyacht industry.

Existing Measurements Today


– MARPOL resolutions and annexes (Annex VI – Prevention of Air Pollution from Ships)
– Energy efficiency measures: EEDI, SEEMP, EEOI

Classification societies

– Green notations as proof of voluntary compliance with additional measures, including all life cycle steps, from design to recycling

Independent labeling systems

– Environmental Shipping Index evaluates performance in reducing air emissions
– Clean Shipping Index includes air pollution as well as chemicals, water and waste
– Blauer Engel for environmentally friendly ship design
