Credibility Through Consistency – Our Electric Vehicle Fleet

We Practice What We Preach

As a law firm specialized in renewable energy, it is natural for us that our convictions are visible in our daily actions. That’s why we have consistently converted our entire vehicle fleet to electric mobility.

Consistently electric – both in the office and for all business activities, we rely exclusively on electric vehicles. This decision is more than just a statement: it is an expression of our deep conviction that the energy transition can only succeed through consistent action.

Authenticity Starts at Our Own Doorstep

Those who advise their clients on implementing offshore wind farms, large-scale solar installations, and intelligent power grids must lead by example. That’s why we provide electric vehicles to all firm employees – including our flexible assistant. Only this way can we authentically advocate for the technologies we legally champion.

More Than Just Mobility

Our electric vehicle fleet symbolically represents our holistic approach:

  • Sustainability in all business areas
