Munich, Wiesbaden, Brixen – August 4, 2026: The companies DFGE, natureOffice, and Terra Institute, united under the “CERTANIA Sustainability” umbrella, will be working even more closely together in the future. By pooling their expertise under the joint umbrella brand CERTANIA Sustainability, they are creating a new, powerful full-service network that combines data, climate expertise, strategy, and transformation into holistic sustainability solutions for businesses. The three independent specialists will collaborate more closely on joint client projects, combining scientific rigor, proven solutions, and organizational transformation.
Comprehensive ESG Expertise for Businesses
The new alliance brings together the ESG solutions offered by the three established specialists to seamlessly cover all areas of corporate sustainability. The spectrum ranges from strategic consulting and complex calculations to participation in international ratings and ESG reporting, effective decarbonization—including tailored CO₂ offsets—and in-depth transformation and operational implementation. Clients gain coordinated access to the expertise of all three companies. Tailored teams of experts are assembled for joint projects.
The three companies will continue to operate independently in the market while strategically pooling their expertise and resources to provide even more comprehensive support to clients.
Statements from Management
Dr.-Ing. Thomas Fleissner, Founder & CEO of DFGE:
“We are very much looking forward to expanding our expertise in the field of ‘Sustainability Intelligence’ through this partnership. As part of the Certania Sustainability expert network, we will be able to tackle our clients’ complex ESG challenges with even larger teams and concentrated expertise, bringing a new level of depth and scientific rigor to our work.”
Andreas Weckwert, CEO of natureOffice:
“What companies do in terms of climate protection should be easy to explain – with reliable data, transparent methodology, and solutions that work in day-to-day business operations. natureOffice brings to the table its many years of experience in CO₂ accounting, tried-and-true software, and direct involvement in its own climate protection projects, such as PROJECT TOGO. Together with DFGE and Terra Institute, we can support our clients even more comprehensively—from a solid starting point to the next effective step.”
Günther Reifer, Founder & CEO of Terra Institute:
“Sustainability can only be achieved through genuine change in corporate culture. Through this partnership, we can provide our clients with even more comprehensive support – from in-depth training and strategic leadership to change processes across the entire ESG spectrum, scaled from the C-suite down to operational teams.”
Moritz Gruber, CEO of CERTANIA:
“At CERTANIA, we believe that independent specialists can achieve more together than they can working in isolation. As the TICC Group, we stand for quality, certification, and compliance – with CERTANIA Sustainability, we support companies every step of the way, from building a robust data foundation to achieving genuine transformation. Our goal is clear: We want to become one of the leading ESG transformation partners in Europe. Closer collaboration among our sustainability experts brings us significantly closer to this goal.”
