ecosys is a Swiss consulting company specialized in the economic analysis of the environment, sustainable development tools (CSR) and public finances


ecosys was founded in 1988 as a spin-off of the Geneva University by Prof. Gonzague Pillet (PhD in economics), Jean-Pierre Cheneval (PhD in chemistry) and Jacques Dozio (Architect). We have been collaborating ever since with different organisations and institutions and contributing our field knowledge and practical skills required for specific projects.

We have an important academic network in Switzerland (Universities of Geneva, Lausanne and Fribourg, as well as the EPFL and the Geneva Business School) and internationally (Universities of Paris in France, of Florida in the USA, of El Jadida in Morocco, of Annaba in Algeria and the Princess Samaya University for Technology in Jordan).

In addition, we have many contacts in international organisations (OECD, CEMT, World Bank, UNDP and UNEP), in the European Union and in Government bodies for Development and Cooperation (GIZ in Germany and DDC in Switzerland).

Our Director, Dr. David Maradan, is lecturer at the Geneva Business School as well as at the Universities of Geneva and Fribourg.
