This study analyses the impacts of economic complexity on environmental performance in BRICS-T countries. Annual data for the period 1999-2021, Durbin-Hausman cointegration test and Augmented Mean Group (AMG) estimator are used in the analysis. The robustness of the Panel AMG results is tested with CCEMG and CS-ARDL methods. The results indicate that economic complexity has a positive impact on environmental performance. An increase of 1% in the economic complexity index increases environmental performance in BRICS-T countries between 0.020% and 1.243%. However, economic growth, energy intensity and population density were found to have a negative impact on environmental performance. Renewable energy use, in contrast, contributes positively to environmental performance.

Bu çalışma BRICS-T ülkelerinde ekonomik karmaşıklığın çevresel performans üzerindeki etkilerini analiz etmektedir. Analizde 1999-2021 dönemi yıllık verileri, Durbin-Hausman eşbütünleşme testi ve Augmented Mean Group (AMG) tahmincisi kullanılmıştır. Panel AMG sonuçlarının sağlamlığı ise CCEMG ve CS-ARDL yöntemleri ile test edilmiştir. Sonuçlar, ekonomik karmaşıklığın çevresel performans üzerinde olumlu bir etkisi olduğunu göstermektedir. Ekonomik karmaşıklık endeksindeki %1'lik bir artış BRICS-T ülkelerinde çevresel performansı %0,020 ile %1,243 arasında artırmaktadır. Bununla birlikte, ekonomik büyüme, enerji yoğunluğu ve nüfus yoğunluğunun çevresel performans üzerinde olumsuz bir etkiye sahip olduğu bulunmuştur. Buna karşılık yenilenebilir enerji kullanımı çevresel performansa olumlu katkıda bulunmaktadır.
