The initiatives taken by the European Union (EU) and the strategies it adopts aim to achieve sustainable development in a long-term perspective. This, however, requires continuous and consistent efforts to minimise the pressure on the natural environment. By obliging and encouraging Member States to take action in the environmental area, the EU wants to be a leader in conducting the green energy transformation. The main aim of the article is to assess the level of advancement of the EU countries (taking into account their division into two groups: EU-13 and EU-15) in making efforts to preserve the natural environment, with a particular emphasis on the position of Poland among the EU countries. An environmental index (EI) was used to make comparisons between EU countries. This index was designed on the basis of selected indicators during a statistical analysis. The Principal Component Analysis and the cluster analysis are employed in the article. This analysis puts forward a claim that it was mainly the countries of the EU-15 (Denmark and Sweden, in particular) that ranked highest in the environmental area in the period analysed and thus are the most advanced in terms of taking action for environmental protection—they took leaders’ positions. Romania and Bulgaria took the lowest positions in these comparisons. Poland’s score was low for the EI in the period analysed compared to the EU-28 countries. Establishing a more effective environmental policy in Member States with the lowest results is most crucial. The consistency of ordering countries according to the EI was noticeable in the period investigated. This proves the stability of the positions occupied by the EU-13 and the EU-15 group. Even though the European Union has made great progress with regard to the protection of the natural environment and green transformation, there is still much more to be done to increase the efficiency of resource use, waste recycling, energy efficiency or RES sharing in energy mixes. |
