Sustainability of G20 Countries within Environmental and Energy Perspectives

Abstract

Sustainability is one of the most significant aims strived to achieve. Energy and the environment are interrelated factors that contribute to sustainability. Measuring energy and environmental sustainability is of utmost importance. The paper’s aim is to analyze the energy and environmental performance of the G20 members. An integrated approach with MCDM methods is proposed. First, we attribute criteria weight via the CRITIC method. Secondly, we evaluate the performance of the G20 countries via the VIKOR and CoCoSo methods. Our results show that Brazil is ranked as the G20 country with the best performance. We may conclude that performance evaluation via MCDM methods may give significant insight into the sustainable development of countries.
