Sustainability Report 2025

Trust as the foundation of sustainable conduct

Trust lies at the heart of BDO’s corporate culture. Trust, however, does not come about by itself; it must be earned day after day through responsible, ethical conduct. 
 
In this 2025 Sustainability Report, we disclose how we deliver on this commitment. We show the progress we have made thanks to targeted process optimisation and measures, and the areas where we still see challenges and risks that we remain determined to address.

Our approach to sustainability

For us, sustainability is an integral part of responsible corporate management and a prerequisite for long-term business success. Our clearly defined action areas, goals and metrics set the direction. They show how we create value – for our people and our clients, for the financial stability of our company, and for society and the environment. 

We reached a significant milestone by receiving our first-ever EcoVadis Silver Medal. This places BDO among the top 15 percent of companies assessed worldwide and confirms the impact of our efforts to date. The award also motivates us to remain committed to the course we have set.

Value for our people

Our understanding of responsibility shapes the way we treat our people. In 2025, we made targeted investments to develop our corporate culture further. We have embedded our values and leadership principles even more firmly into our daily work and established them as mandatory topics in annual performance reviews. At the same time, we have introduced digital solutions for key HR processes to better support our leaders and employees in their day-to-day work. Although we have not yet fully achieved our employee turnover target, the key figures indicate a clear improvement. This strengthens our resolve to continue on the path we have chosen.

Value for our clients

Many organisations are faced with the challenge of driving progress in digitalisation and sustainability while maintaining reliable operations. To support them, BDO has consolidated its digital departments and created ‘BDO Digital’ – a Swiss-wide centre of excellence combining technological expertise, industry knowledge and exceptional methodology with a network of more than 100 specialist advisors. With our dedicated Sustainability Services, we have also succeeded in providing practical support to organisations of all sizes in times of regulatory uncertainty.

Financial stability

We ensure the long-term stability and independence of the company through profitable growth, innovation and responsible corporate governance. In 2025, we further professionalised our risk management and digitalised it fully for the first time. This enabled us to significantly increase the transparency of financial and non-financial risks along with our ability to control them. Targeted investments in governance, compliance and information security strengthen our operational resilience and help us to identify and minimise risks at an early stage. With the introduction of a new reporting platform for employees and external stakeholders, we are enhancing our compliance structures. We have also taken further steps in the areas of digitalisation and artificial intelligence to increase efficiency and embed innovation for the long term.

Contribution to society

As a Swiss company, we take our responsibility towards society and the environment seriously. Over a hundred of our people are involved in politics or charitable foundations, thereby making an important contribution to the development of municipalities and institutions. In addition, we allocate a substantial annual sponsorship budget to sports, culture, business and social initiatives. This commitment is underscored by more than 600 hours of corporate volunteering in regional organisations. At the same time, we work continuously to minimise the negative impact of our business activities on the environment through targeted climate protection measures. In the reporting year, we were able to further reduce emissions from business travel by making greater use of sustainable mobility options such as increased train travel and the use of electric vehicles.
