N2O için Çevresel Kuznets Eğrisi Hipotezinin Test Edilmesi

Abstract

Sera gazlarının en zararlılarından biri olan N2O çevreye büyük zararlar vermektedir. CO2 kadar dikkat çekmemesine rağmen, bu gazın emisyonunu azaltmak için uygulanacak politikalar sürdürülebilir bir çevre ve ekonomi için büyük önem taşımaktadır. Politikaların zamansız uygulanması verimsizliğe ve kıt kaynakların boşa kullanılmasına neden olabileceğinden, politikaların uygulanma zamanı dikkatlice seçilmelidir. Bu noktada, Çevresel Kuznets Eğrisi (ÇKE) politikaların zamanlamasının belirlenmesine büyük katkı sağlamaktadır. Bu çalışmada, N2O salınımının ekonomik büyüme ile ilişkisini incelemek amacıyla, seçili 20 Avrupa ülkesi ve Türkiye'ye ait panel verileri kullanarak N2O salınımı için ÇKE ilişkisini araştırdık. Bu amaçla, 1992-2017 dönemine ait panel veri setine panel ARDL testi uyguladık. Panel ARDL sonuçlarına göre, N2O salınımı ile ekonomik büyüme arasında istatistiksel olarak anlamlı uzun vadeli bir ilişki bulunmaktadır. Bu ilişki “N” şeklinde bir eğri oluşturmaktadır.

Testing Environmental Kuznets Curve Hypothesis for N2O

Abstract

N2O, one of the most harmful of greenhouse gases, causes great damage to the environment. Although it does not attract as much attention as CO2, policies to reduce the emission of this gas are of great importance for a sustainable environment and economy. As the untimely implementation of policies can lead to inefficiency and waste of scarce resources, their timings should be considered carefully. At this point, the Environmental Kuznets Curve (EKC) approach makes a great contribution to the determination timings of policies. In this study, we investigated the EKC relation for N2O emission using the panel data of selected 20 European countries and Turkey, to examine the relationship between N2O emissions and economic growth. For this purpose, we applied the panel ARDL test to the panel data set for the period 1992-2017. According to the panel ARDL results, there is a statistically significant long-run relationship between N2O emission and economic growth. This relationship forms an "N" shaped curve.
