The story of akzente



At the first UN summit in Rio de Janeiro in 1992, more than 180 nations signed the guiding principle of sustainable development. Only a few months later, in the spring of 1993, Sabine Braun and Renate Volk founded the consulting firm akzente in Munich, Germany. Its objective: to build a bridge between business and society, and to support them in providing transparency and bringing about transformation.



Globalization gained momentum, fueling fear all around the world. In 1999, UN General Secretary Kofi Annan initiated the Global Compact in Davos to give the world a humane face. On behalf of the German Federal Environmental Foundation (DBU), akzente experimented with ways of implementing sustainability in companies and published a guideline for this purpose.



With the EU Green Paper, corporate social responsibility became part of the political equation. Shortly after the corruption scandal at Siemens, akzente helped the company expand its sustainability reporting. Numerous other scandals proved just how important a new awareness for governance and compliance was.



In the spring of 2008, the report of the Intergovernmental Panel on Climate Change (IPCC) put out an urgent warning about climate change. Even the German tabloid BILD published an extensive report. In the fall of the same year, the collapse of the Lehman Brothers Bank triggered a global financial crisis. Sustainability gained a new meaning. At the time, akzente became involved in reporting, consulting and communication projects for Commerzbank, HypoVereinsbank and the KfW Banking Group.



The collapse of the Rana Plaza textile factory in Bangladesh pushed forward discussions about working conditions along supply chains. In Germany, the Partnership for Sustainable Textiles (Textilbündnis) and the German National Action Plan for Human Rights (NAP) were established. The European CSR guidelines obliged companies to become more transparent. akzente gained more and more B2C companies as its clients. In 2014, we developed a guideline for implementing the German Sustainability Codex in medium-sized companies.


For our 25th anniversary, we’ve set our sights on the future. The opening of our Berlin office is bolstering the network linking the world of politics, associations and NGOs. Our 30-strong Munich-based team is more powerful than ever. In just ten weeks, akzente created the most comprehensive study on implementing the CSR reporting obligation on behalf of the German Global Compact Network and ecosense.

Thomas Melde first encountered the concept of sustainable development during his studies of political science, law and sociology in Leipzig and Paris.
