Mariëlle de Sain

Consultant: Renewable Energy & Stakeholder Management





Mariëlle de Sain has nearly 20 years of experience in the area of sustainable energy and living conditions. Her projects are characterised by the consideration and integration of various functions in urban and rural areas, port and industrial areas and the link with infrastructure and energy grids.

As an adviser and project manager at Pondera, Mariëlle is responsible for projects involving sustainable energy and living conditions. These projects often take the form of feasibility studies, environmental assessments, environmental impact assessments and environmental management.
