The article specifies the economic and environmental efficiency in the metal industry in individual EU countries in 2015. The study applies Data Envelopment Analysis (DEA), which is a non-parametric method based on production theory and the principles of linear programming. It enables one to assess how efficiently a firm, organization, country, or such other decision making unit (DMU) uses the available inputs to generate a set of outputs relative to other units in the data set. The analysis gives a possibility to create a ranking of countries. The results point out the reasons of the inefficiency and provide improving directions for the inefficient Decision Making Units.Keywords: efficiency, environment, metal industry, Data Envelopment Analysis, Europe
