Our philosophy
and mission

We think big and holistically - which is precisely why we start with concrete and pragmatic steps. We are driven by the desire to make sustainability measurable, implementable and ultimately meaningful: from Hamburg for a future in which we all enjoy living and working.

Sustainability is not a feeling, but a core strategic issue for companies, which we prefer to discuss on the basis of data. This is why we support and assist organizations in collecting and collating data, classifying and understanding key figures and facts relating to sustainability. Not only because the reporting obligations of more and more companies require it, but above all because only what is measurable is also visible and can therefore be changed for the better.

A sustainability strategy can only be fully effective if it is seamlessly integrated into a company's overall strategy and is supported and implemented with commitment. We advise organizations on how they can set up viable sustainability management systems that track, reflect on and continually adjust specific measures and steps with a view to the goal. We enable the people who work with these systems to manage their issues as effectively as possible and ensure efficient knowledge transfer within the company.

We like green, but not greenwashing. Only meaningful sustainability efforts can solve our local and global sustainability challenges. That's why we make sure that our advice is as concrete as possible and in line with the company's own guiding principles. We try to avoid mere concept papers or measures that disappear into a drawer and do not really contribute to sustainable business practices. Instead, we work together with companies to find levers that can really make a positive difference.

Our network
