The concept of sustainable competitiveness of a country is a newly created category by the World Economic Forum 2011. In the paper, an empirical analysis of sustainable competitiveness of European countries has been carried out, according to the World Economic Forum data for the year 2012-2013. The key research question regarding the trade-off between the Global Competitiveness Index (GCI) and the Sustainability- Adjusted Global Competitiveness Index (SCI) of European countries in 2013, has led to a negative answer, i.e., the empirical analysis did not confirm the negative relationship between these two phenomena.
