The paper aims to evaluate the environmental performance efficiency of (European Union (EU) countries and to calculate Türkiye's position among these countries. The performance of EU countries and Türkiye for the period 2010-2022 is assessed using the variables of Gross Domestic Product (GDP), Greenhouse Gas Emissions (GHG), Material Flows (MF) and Tree Cover Loss (TCL). For this purpose, Decoupling Analysis and Malmquist Total Factor Productivity Index (MTFPI) were applied. As a result of the analysis, there was no productivity change in Lithuania, Slovakia, Sweden and Türkiye. In the same period, there is an increase in productivity change for 12 countries and a decrease for 12 countries. In general, total factor productivity increased in 1 country and decreased in 27 countries during the study period. The country with the highest increase in technical productivity change, in other words technological development, was Hungary with 3.7 percent. According to the decoupling elasticities of these 28 countries, the decoupling elasticity indices of GHG and MF are positive for Türkiye and Greece. For Croatia, Cyprus, Estonia, France, France, Germany, Portugal and Spain, the decoupling index of GHG and MF from GDP is negatively elastic for that period. For the decoupling index of TCL from GDP, Germany shows an elasticity greater than one in that period.

Bu çalışma, Avrupa Birliği (AB) ülkelerinin çevresel performans verimliliğini değerlendirmeyi ve Türkiye'nin bu ülkeler arasındaki konumunu hesaplamayı amaçlamaktadır. AB ülkeleri ve Türkiye'nin 2010-2022 dönemi performansı Gayri Safi Yurtiçi Hasıla (GSYH), Sera Gazı Emisyonları (SGE), Malzeme Akışları (MA) ve Ağaçla Kaplı Alan Kaybı (AKAK) değişkenleri kullanılarak değerlendirilmiştir. Bu amaçla, Decoupling (Ayrıştırma) Analizi ve Malmquist Toplam Faktör Verimliliği (MTFV) Endeksi uygulanmıştır. Analiz sonucunda Litvanya, Slovakya, İsveç ve Türkiye'de verimlilik değişimi yaşanmamıştır. Aynı dönemde 12 ülke için verimlilik değişiminde artış, 12 ülke için ise azalış söz konusudur. Genel olarak, toplam faktör verimliliği çalışma dönemi boyunca 1 ülkede artmış, 27 ülkede ise azalmıştır. Teknik verimlilik değişiminde, diğer bir deyişle teknolojik gelişmede en fazla artış gösteren ülke yüzde 3,7 ile Macaristan oldu. Bu 28 ülkenin ayrışma esnekliklerine göre, SGE ve MA ayrışma esneklik endeksleri Türkiye ve Yunanistan için pozitiftir. Hırvatistan, Kıbrıs, Estonya, Fransa, Almanya, Portekiz ve İspanya için SGE ve MA'nin GSYH'den ayrışma endeksi o dönem için negatif esnektir. TCL'nin GSYH'den ayrışma endeksi için, Almanya söz konusu dönemde birden büyük bir esneklik göstermektedir.
