Evaluating the Net Zero Policy Performances of European Countries Through DEA.

Addressing climate change and its environmental impact is one of the greatest challenges of modern life. Most of today's sustainable strategies are essentially related to the intent of reducing overall carbon dioxide emissions. The net zero goal lays the foundation for a sustainable future. This study aims to measure the performance of European Countries based on carbon emissions. To measure performance, Pure Environmental Performance Index and Mixed Environmental Performance Index Data Envelopment Analysis (DEA) methods are used. Decision-making units (DMUs), inputs and outputs are determined. Input is identified as Primary Energy Consumption. Outputs are selected as Gross Domestic Product (GDP), Carbon dioxide (CO2) emission, Nitrous Oxide (N2O) emission. According to performance results, Albania, Lithonia, Malta, and Montenegro are classified as efficient countries via the two models. The results shows that the European Countries should take the required measures of the Paris Conference till 2050 to reduce the damage to the environment. [ABSTRACT FROM AUTHOR]
