TÜRKİYE’DE ÇEVRE VERGİLERİ VE EKOLOJİK AYAK İZİ İLİŞKİSİ: EKC HİPOTEZİ BAĞLAMINDA BİR ANALİZ

Öz

İklim değişikliği ve çevresel bozulmanın giderek artan etkileri, sürdürülebilir kalkınma hedeflerine ulaşmada kamu politikası araçlarının önemini ön plana çıkarmaktadır. Bu çalışma, 1994–2023 dönemine ait yıllık veriler kullanılarak, Çevresel Kuznets Eğrisi (EKC) hipotezi çerçevesinde çevre vergileri ve yenilenebilir enerjinin Türkiye’nin ekolojik ayak izi üzerindeki etkilerini incelemektedir. Analizde uzun dönem ilişkilerini değerlendirmek amacıyla Genişletilmiş ARDL yaklaşımı uygulanmıştır. Bulgular, Türkiye için EKC hipotezinin geçerli olduğunu ve çevre vergilerinin ekolojik ayak izini azalttığını göstermektedir. Buna karşılık, yenilenebilir enerjinin etkisinin istatistiksel olarak anlamlı olmadığı tespit edilmiştir. Ayrıca, alternatif tahmin yöntemleri (FMOLS, DOLS ve CCR) ile yapılan sağlamlık analizlerinde de benzer sonuçlara ulaşılmıştır. Elde edilen bulgular, çevresel sürdürülebilirliğin sağlanmasında çevre vergileri gibi mali araçların önemine dikkat çekmekte ve bu vergilerin çevresel baskıları azaltmada etkili bir politika aracı olabileceğini göstermektedir.

THE RELATIONSHIP BETWEEN ENVIRONMENTAL TAXES AND ECOLOGICAL FOOTPRINT IN TÜRKIYE: AN ANALYSIS IN THE CONTEXT OF THE EKC HYPOTHESIS

Abstract

Growing concerns over climate change and environmental degradation have brought public policy instruments to the forefront of efforts toward achieving sustainable development. This research explores the influence of environmental taxation and renewable energy on Türkiye’s ecological footprint within the framework of the Environmental Kuznets Curve (EKC) hypothesis, employing annual data covering the years 1994–2023. The analysis adopts the Augmented ARDL approach to examine long-term dynamics. The results confirm the validity of the EKC hypothesis for Türkiye, revealing that environmental taxes contribute to a decline in the ecological footprint, whereas the role of renewable energy is statistically insignificant. Additional robustness analyses conducted with alternative estimators—FMOLS, DOLS, and CCR—produce consistent outcomes. These findings highlight the significance of environmental fiscal measures in advancing ecological sustainability and suggest that environmental taxes can function as an effective policy tool for reducing environmental pressures in Türkiye.
