Its core competencies lie in sustainable development, decarbonization, and energy efficiency, supporting both companies and regions in generating economic, environmental, and social value. Services range from designing strategic roadmaps to implementing operational projects and providing ongoing monitoring in areas such as low-carbon transition, energy performance contracts, and responsible investment strategies.

This corporate acquisition by Oteis is strategic, aiming to integrate GreenFlex's deep expertise and established client relationships. The move is expected to enhance Oteis's capabilities in delivering holistic sustainable solutions, particularly in response to increasing market demand for environmental and energy efficiency services.
