Sustainability Vision

As a law firm, we attach importance not only to our legal services, but also to our responsibility towards society and the environment. Minimising our impact on the climate and strengthening our social engagement are central to this. As a firm, we feel strongly committed to social and other issues. In our day-to-day operations, we observe that environmental impact is becoming increasingly important, even in legal cases. Increasingly stringent sustainability criteria are being set for the granting of planning permission for property or other projects, as well as for the awarding of public contracts. As a firm, we strive to prepare and guide our clients as effectively as possible in this regard from a legal perspective.

Furthermore, as a firm, we want to do our bit towards an ecological, economic, equitable and sustainable future. With this in mind, we at GSJ have developed a clear vision that reflects sustainability as a core value of our firm:

“GSJ aims to be the leading legal partner in Flanders and beyond, combining expertise and advice with social responsibility. We demonstrate that economic progress goes hand in hand with care for the climate, social justice and fair governance. As a law firm, we play a key role in making society more sustainable – by providing clients with sustainable advice, contributing to a just legal system and organising our operations in an environmentally conscious and transparent manner. In this way, we build lasting trust with clients, within our organisation and in society.”

Our mission statement is as follows: GSJ provides legal expertise of the highest standard, with respect for the rule of law, people and the environment. We treat our people, resources and relationships with care, and are committed to legal solutions that are valuable and responsible not only today but also in the long term. Our core values – integrity, professionalism and innovation – guide every decision and every collaboration.

We incorporate the concept of ‘sustainability’ into our business operations through the 5 Ps: People, Planet, Prosperity, Peace and Partnership. The United Nations has also categorised the Sustainable Development Goals into these five dimensions. The 17 SDGs (Sustainable Development Goals) form the cornerstone for eradicating global poverty, tackling inequality and protecting the environment and world peace by 2030.

As a law firm, we do this by, amongst other things, prioritising health and wellbeing at work, adopting a ‘paper-low’ approach and working digitally wherever possible, encouraging sustainable mobility amongst our staff, donating financial support and legal services to charities, collaborating with local partners, and much more. For us, CSR is about finding the right balance between these five dimensions.

  • Knowledge is the key word at GSJ. It is no coincidence that our slogan is ‘Shared knowledge is double knowledge’. Our solicitors are regularly invited to speak at seminars, and we sponsor the ALEC and AHLIC chairs. In this way, we as a firm seek to contribute to high-quality academic research and education in our city within the sectors in which we operate on a daily basis.
  • We act as a sponsor of De Conferentie, the study centre dedicated to the practice of legal scholarship in our own language, and are a partner of the Antwerp faculty club Sofia.
  • Since 2021, we have been an alliance partner of a British and Dutch law firm, TLT LLP and Holla legal & tax. This enables us to support internationally-oriented clients better than ever before. Recently, the Spanish law firm BPV Abogados also joined this alliance.
  • Since 2025, we have had a partnership with 180 Degrees Consulting Antwerp, through which we mentor students in developing legal advice for non-profit organisations and social enterprises.


In October 2025, we were awarded the “SDG Pioneer” certificate. In June 2026, we were also awarded the Voka Charter for Sustainable Entrepreneurship certificate for the fourth year running (VCDO). This recognition was the result of a comprehensive action plan featuring initiatives such as building up ESG expertise, organising sustainability training courses, print campaigns, initiatives on sustainable mobility, wellbeing and health at work, donating financial support and legal services to various charities, and much more besides.

So, whilst a great deal of effort has already been put into our business operations, the work is far from over and the challenges we face as a society are considerable. Sustainable business is a process of growth, and we are proud that our firm has taken the first steps. We look forward to the next sustainability challenges – or rather, “collaborative challenges”. The challenge lies in working together: our behaviour and our actions are the key to success!
