Best Practice

Each member of our management team is personally responsible for adhering to ethical principles and implementing best practice standards as essential components of our corporate philosophy.

With our corporate social responsibility program, DUPUIS demonstrates awareness of the fact that our responsibility extends beyond the financial sphere. Our firm feels a particular sense of responsibility for society, changes in sociocultural structures and the ecological sustainability of real estate in Germany.


In order to recognize the importance of this social and ecological responsibility, and stay in line with our firm’s increasing awareness for sustainability, DUPUIS is currently working closely with the Institute for Corporate Responsibility Management (ICRM) of Steinbeis University Berlin as part of a public project of the Federal Ministry for Labor and Social Affairs and the European Social Fund (ESF).


Our goal is to implement solid and enduring corporate social responsibility measures relating to the firm’s operations.

Each year, DUPUIS donates a fixed percentage of its earnings to social causes. Among projects worthy of support, we select those with the most streamlined and cost-efficient management structures, so that the highest possible share of funding will go directly to those who need it most.


We favor projects which support education and provide basic medical care for underprivileged children, primarily in Sub-Saharan Africa and the US.
