About Mariella

As a self-employed person, I contribute with my know-how to ensure that SMEs in Europe operate sustainably. In doing so, I focus on authenticity, trust and transparency. Our cooperation is the focus for me: a strong exchange is needed; I want to stay close to and with the client, for the successful realisation of goals in terms of sustainability!


My consulting concept shall not only be successful, but also true to the vision and meaningful - sustainability shall be lived!

Uniquely different

I am a GRI Certified Sustainability Professional. I am therefore well prepared for the EU reporting standards! As a member of various international communities, I am well connected in Europe and South America!
As a lawyer, I have many years of professional experience in international cooperation and intercultural legal advice for companies; since 2020, I have focused on sustainability in private sector organisations.


In 2021, I completed the Leading Sustainable Corporations Programme at Saïd Business School (University of Oxford); in 2022, I achieved the certification as a GRI Certified Sustainability Professional from the Global Reporting Initiative.


I am an open-minded, internationally versed person with interdisciplinary skills, which I like to apply in intercultural contexts.
