Message from the Country Managing Partner and Sustainability Leader of EY Luxembourg
We are here to present our EY Luxembourg Sustainability Report covering financial year 2025.
At EY, we believe that sustainability is not just a responsibility, it’s a shared opportunity to shape a resilient and inclusive future. In 2025, this belief continues to guide our actions as we embed sustainability into every aspect of our business and culture. We see it as a powerful driver of innovation and collaboration, capable of mobilizing entire ecosystems to address the complex challenges facing our planet.
That’s why we’ve moved beyond intention to action: setting ambitious targets, measuring our progress, and empowering our people to lead by example. Through their skills, insights, and commitment, our teams are helping to accelerate the transition to a more sustainable world, one decision, one project, one partnership at a time.
EY Luxembourg remains committed to staying aligned with the evolving regulatory landscape shaped by the Corporate Sustainability Reporting Directive, which drives transparency, accountability, and long-term thinking across the European business ecosystem. In 2025, the European Commission introduced the “Omnibus” simplification package, significantly amending the CSRD to reduce administrative burdens and enhance proportionality. Under the proposed changes, approximately 80% of companies will be removed from the scope of the CSRD, with future reporting obligations focused only on large businesses, and reporting deadlines postponed for several entities by two years.
We remain committed to supporting our clients and stakeholders in navigating this evolving framework and Shaping the future with confidence. Explore our interactive Report to learn more about our sustainability journey and impact.

Our corporate sustainability strategy
We believe we can do more in addressing evolving sustainability challenges
Our approach to sustainability
As part of our Sustainability Report, we present our corporate sustainability approach.
This approach is based on the following pillars:
1. Our people – our most valuable asset.
2. Our culture of integrity, with the Code of conduct that is at the core of our policies.
3. Our impact beyond the organization through EY Ripples, EY’s global Corporate Responsibility Program.
4. Our environmental commitment reflects EY’s global ambition to reduce our ecological footprint and promote sustainable business practices. EY Luxembourg continues to implement responsible procurement and waste management strategies, aligned with EY’s Global Environmental Statement and Supplier Code of Conduct.
5. Our clients, which we aim to guide in creating long-term sustainable value as an integrated part of their business.
- Our Strategy & Business Model
- Our Governance
- Materiality assessment of sustainability impacts, risks and opportunities
In FY25, EY introduced its new global strategy, All in, under the leadership of Janet Truncale as EY Global Chair and CEO. This strategic shift represents a renewed commitment to purposeful growth, placing emphasis on areas where EY can lead and create long-term value. The strategy builds on the foundation of NextWave but goes further in aligning EY’s global ambitions with the evolving needs of clients, employees and society.
All in focuses on harnessing the power of technology, particularly artificial intelligence and data-driven innovation, to help organizations transform and remain competitive. It also reinforces EY’s role in delivering high-quality managed services and deepens its commitment to sustainability, not just as a compliance issue but as a driver of strategic advantage. At the same time, the strategy maintains a strong focus on audit quality, recognizing its essential role in building trust in financial markets.
This new direction is not only about growth, itis about growing with intention, with integrity, and with impact. EY Luxembourg has embraced the All in strategy by ensuring that global priorities are translated into meaningful local action. Through this alignment, EY Luxembourg continues to support its clients in navigating complexity, unlocking opportunity, and contributing to a better working world.
EY remains a proud signatory of the United Nations Global Compact , reaffirming our commitment to its Ten Principles and to the advancement of the Sustainable Development Goals (SDGs). As an active participant since 2009, we continue to report annually on our progress, with our next Communication on Progress due in 2026.
We support digital pioneers in protecting data integrity, advising governments on emerging global challenges, and help unlock medical breakthroughs through advanced analytics. We deliver high-quality audits that foster trust in financial markets, and we help organizations navigate climate risks and embed sustainability into their core strategies. In essence, we work with entrepreneurs, companies and institutions to solve their most pressing challenges and seize new opportunities.
At EY Luxembourg, we believe that responsible growth is the key to long-term success. We are proud to collaborate across ecosystems — clients, communities, and partners — using our knowledge and experience to drive positive change.
We continue to invest in our people, empowering them to develop the mindsets and skills needed to lead in a rapidly changing world. Through initiatives like EY Badges, our professionals gain future-focused capabilities in areas such as AI, sustainability, and inclusive leadership.
Our people and alumni form a vibrant network that brings our purpose to life, both within EY and beyond. We believe that diversity and inclusiveness are essential to growth, and we are committed to fostering a culture where every individual feels valued and empowered to contribute.
EY’s matrix structure, combining service lines with sector-specific expertise, enables us to deliver tailored, multidisciplinary solutions to our clients. This approach ensures that we bring the right knowledge to every engagement, regardless of its nature or complexity.
For more information, please refer to section 1.3.2: Overview of EY Luxembourg business in the context of sustainability reporting.
In July 2020 the role of Sustainability Leader was created within EY Luxembourg and entrusted to Partner Renaud Breyer. Renaud oversees the development of corporate sustainability strategy, planning and reporting and accounts to the Country Leadership Committee for any material ESG matter.
Engaging our stakeholders allows us to understand their expectations and how they perceive our business, so that we can identify the main risks and opportunities, adapt our approach and improve our performance.
1. Clients
In order to support our clients, we aim to empower organizations to innovate and transform. Our role as an agent in the financial world enables us, due to the diversity of our assignments and our clients, to monitor the underlying trends transforming society and to formulate questions that help to develop our clients’ models and their uses, opening doors to new solutions.
EY has developed a formal quality assessment process for measuring satisfaction of our clients.
2. Employees
EY people proudly represent our most valuable assets. We apply a complex approach which is used to nurture talents, enhance professional skills, and facilitate communications within EY, for example:
- Employees are guided within the organization by their mentors - counselors, who help them to develop short- and medium-term views of their careers.
- Various professional and soft skills trainings are offered across different topics and sectors.
- The upward feedback process introduced in 2016 helps our colleagues to develop and grow, be recognized for achievements and be advised in challenging situations.
- Lastly, our engagement surveys (EY People Pulse) help us analyze the business climate and the areas for improvement that our employees and partners would like to prioritize.
3. Associations and Academia
EY has a privileged view of the financial world due to the diversity of its service lines and the sectors in which it operates, not to mention:
- The many think tanks and networks in which the company is involved
- The publication of studies and analyses
- The influx of young people joining the world of work and seeking mentorship
4. Public Authorities
Our partners and employees can be asked to contribute by setting common standards and reflecting on the regulatory environment in which we operate. Therefore, EY actively cooperates with various ministries and regulatory bodies for regulatory framework development initiatives.
5. Other Stakeholders
Moreover, EY Luxembourg constantly engages with:
- Competitors: to create a healthy competitive environment, in which we grow simultaneously
- Suppliers and sub-contractors: to promote accountability within our supply chain and innovation
- EY Global: Providing the same excellence all over the world. Ensuring that our clients benefit from an integrated, cross-functional network
The materiality analysis consists of identifying the various issues related to our economic, social and societal responsibility and arranging them in hierarchical order.
To aid in this understanding, from 2024 we started to conduct a formal impact materiality assessment, in line with the ESRS principles, to prioritize topics that are both: most important to EY’s business performance and where EY can have the greatest impact on stakeholders. Our goal is to act on our findings by embedding these topics even more deeply into our business strategy, in response to stakeholders’ needs.
We conducted materiality assessments in the past and are committed to updating them on a regular basis to reflect changes in business and stakeholder priorities, along with global trends.
The impact materiality assessment, based on the recommendations provided in the ESRS, was conducted by professionals of the Sustainability Team and guided by the GRI framework, future reporting requirements, best market practices and the EY Global Materiality Assessment. The process included senior leadership input, under the guidance of our Sustainability Leader, Renaud Breyer; external stakeholder interviews with clients, regulators and academics; industry and peer analysis; employee focus groups; internal and external media and communication reviews.
From previous materiality assessments and looking ahead, we continue to further integrate these topics into our governance model and enterprise risk processes. This allows us to fully integrate sustainability into EY strategic priorities.
The results of the most recent assessment are indicated in the following materiality matrix. All topics indicated are material to EY Luxembourg, with the topics in the upper-right quadrant being the most material to EY stakeholders and EY business performance with opportunity for greatest impact.
As we have prioritized the most material topics, we acknowledge the interconnected nature of ESG topics and consider all topics listed on the matrix as areas of importance — understanding the progress made in one area may have an impact on others.
This impact materiality matrix, in line with the EY Global materiality matrix, has enabled us to identify three key priorities for EY Luxembourg:
- Supporting the creation of long-term value through our services that enables us to shape the future with confidence. Our goal is to act in a transparent and ethical manner
- Placing greater emphasis on our people and communities, developing their talents and making a significant social impact
- Being a corporate citizen, reducing our carbon footprint and considering environmentally friendly practices
Our materiality assessment also considers several risks that the Company is facing.
Managing risk is a strategic priority for the management of the Company, we have spent time looking keenly at the world around us, speaking with people inside and outside of EY: leading thinkers, clients and our people.
Our culture is the commitment to quality. Our infrastructure has been designed to support quality.
The principal components of our quality-control program are the following:
Instilling professional value.
- The senior leadership sets the right tone at the top, demonstrating this through its behavior and actions
- We promote a culture of integrity, as well as the performance of high-quality audits
- Among our professionals, they are bound by our Global Code of Conduct
Internal quality-control system. We continue to invest in initiatives to promote enhanced objectivity, independence and professional skepticism.
Client acceptance and continuance. Our global policy on client and engagement acceptance sets out principles for determining whether to accept a new client or a new engagement, or to continue with an existing client or engagement.
Performing audits. Our EY Global methodology provides a global framework for high-quality audit services through the consistent application of thought processes, judgments and procedures in all engagements.
Review and consultation. Our policies describe the requirements for timely and direct executive participation on audit and the level of reviews of the work performed. Our consultation requirements are built upon a culture of collaboration and designed to involve the right resources. Engagement quality reviews are performed by audit partners in compliance with professional standards.
Audit partner rotation. EY supports mandatory partner rotation to help strengthen auditor independence. We comply with the requirements set up by the IESBA and Luxembourg law, as well as the SEC, where required.
Audit quality reviews. The global audit quality review program is the cornerstone to EY's effort to maintain and improve audit quality.
External quality-assurance review. The Company audit practice and its registered statutory auditors are subject to annual inspection by the CSSF.
Independence practices. EY's independence practices are designed to enable EY in Luxembourg and our people to comply with the independence standards applicable to specific engagements.
Creating high-performing teams. EY is building a better working world for its people by recruiting, managing and retaining top talent and developing the highest-performing teams and outstanding leaders. In addition, EY teams have a legacy of over 20 years in providing sustainability, and environment, social and governance (ESG) services. This enables us to help protect and create value for all stakeholders and shape the future with confidence. We call this value-led sustainability and it’s everybody’s business.
