TWIN4ECO Project

The Twin4ECO project is designed to boost the research excellence and increase the visibility of the Sofia University Faculty of Economics and Business Administration (FEBA) in the field of sustainable energy economics and innovation management as an answer to the national and regional realities and EU targets in the field of energy and sustainability.

Relying on a transdisciplinary holistic research and management capacity building approach, the project will develop and implement a comprehensive set of measures, including joint scientific strategy building, networking activities, knowledge transfer, exchange of best practices, joint research activities and establishment of a long-term collaboration between FEBA and four internationally leading research institutions from EU countries: EWI (Germany), UG (the Netherlands), TU WIEN (Austria) and TU Dublin (Ireland).

Thus, Twin4ECO will contribute to turning FEBA into a national point of research excellence and an institution with a strong regional (and international) significance in the field of sustainable energy economics and innovation management.
