Our CSR Strategy
As a signatory of the United Nations Global Compact since 2019, we have structured our actions around the Sustainability by Leyton programme, a common framework that brings together our initiatives in support of the environment, social equity and broader societal impact. It is structured around three key pillars: Green Leyton / Leyton For All / Innovate with Leyton.
Driving the environmental transition
With Green Leyton, we have been working for several years to reduce the environmental impact of our activities. Following an initial carbon assessment conducted in France in 2022, the approach was extended to the Group’s 15 countries in 2023 and updated in 2024 and 2026. It is supported by initiatives including a Green IT policy, more sustainable mobility, and employee engagement.
Promoting equal opportunities and developing talent
Leyton For All brings together the Group’s initiatives to foster an inclusive and equitable working environment. The approach focuses on three priorities: diversity and inclusion, health and well-being, and skills development. It is supported by training, support and solidarity initiatives tailored to the different countries and professions across the Group.
Balancing impact and performance
Innovate with Leyton reflects our commitment to placing our clients at the heart of our organisation, continuously seeking to improve the quality of the support we provide. We work alongside partners and key stakeholders across our ecosystem to support innovation and help develop new solutions. This value creation takes place within a framework of responsible business conduct, founded on ethics and trust.

Leyton x SailGP
Harnessing the power of high-frequency data to drive a net-zero future.
For over two decades, Leyton has been a catalyst for innovation. Our alliance with SailGP – the world’s most sustainable and technologically advanced racing league – is more than a partnership; it is a shared laboratory for the future. By integrating our deep expertise in R&D tax incentives and energy transition with the high-frequency data streams of 50-knot F50 catamarans, we are proving that ecological responsibility is the ultimate driver of economic efficiency.
Together, we are not just racing; we are pioneering. From optimising foil aerodynamics using advanced carbon-tracking algorithms to implementing circular economy principles across the league’s global operations, our work ensures that every mile sailed contributes to a net-zero horizon. This is the story of how data-driven consulting meets the raw, unyielding power of the ocean to create a legacy that outlasts the race.
