A strong network for more sustainability

Founded 1999 as spin-off of the Technical University of Munich we work in the field of eco-balances, carbon footprints and CSR reporting for more than two decades. Regardless if you are an SMB or a global player with several hundred locations and despite if you are in the process of establishing your first CSR report or if you take part in international rankings: depending on your specific goals and strategy we offer you services which will facilitate your company’s way to sustainability.

“Our goal is to provide our customers with solutions, rather than creating new problems. We want to get our customers off the ground so they can focus on what really matters: driving sustainability across the enterprise. And we’re always ready to take on new challenges that face our customers. “

Based on the calculations, we now can set a realistic saving potential and continue to drive the implementation of specific measures worldwide forward.”

“Through the critical review of the DFGE, the EcoVadis Response Check, we were able to concentrate on the essentials in the EcoVadis assessment – to reflect our CSR performance as realistically as possible.

“For us, waste disposal means recycling raw materials with the aim of recycling them totally and closing the cycle. Sustainability is not only a core component of our services, but also an integral part of our corporate vision.

However, sustainable economic activity can only be achieved if CO2 emissions are transparently identified and validated. Only then saving potentials can be identified, planned and implemented in a comprehensive manner.

The DFGE TopDown approach was the best way for us to capture Scope 2 and 3 emissions and holistically address sustainability issues.”
