Çalışmanın temel hedefi, çevre politikalarının etkinliğini ve sürdürülebilirlik hedeflerine ulaşmada ekolojik vergilerin potansiyel rolünü ortaya koymaktır. Bu çerçevede, 2006-2020 dönemine ait G-20 ülkelerinin yıllık verilerinden faydalanarak panel ARDL analizi yöntemi kullanılmaktadır. Bulgular, uzun dönemde ekolojik vergilerin karbon emisyonlarını negatif etkilediğini ve istatistiki açıdan anlamlı olduğunu göstermektedir. Öte yandan, bulgular, kısa dönemde ekolojik vergiler karbon emisyonları ilişkisinin istatistiki açıdan anlamsız olduğunu göstermektedir. Bu sonuçlar, mevcut ekolojik vergi yapısının karbon emisyonlarını azaltmada uzun dönemde yeterli olduğunu gösterirken Pigovian vergilerinin teorik çerçevede öngörüldüğü şekilde etkin olduğunu göstermektedir. Bu kapsamda, ekolojik vergilerin yeniden yapılandırılması, piyasa tabanlı mekanizmaların geliştirilmesi ve yeşil teşviklerin verilmesi gibi politikaların etkinliğinin artırılması küresel düzeyde karbon emisyonlarını daha fazla azaltabilir.

Impact of Ecological Taxes on Carbon Emissions in G-20 Countries: Panel ARDL Analysis

Öz

The main goal of the study is to reveal the effectiveness of environmental policies and the potential role of ecological taxes in achieving sustainability goals. In this context, the panel ARDL analysis method is used using the annual data of G-20 countries for the period 2006-2020. The findings show that ecological taxes negatively affect carbon emissions in the long run and are statistically significant. On the other hand, the findings show that the relationship between ecological taxes and carbon emissions is statistically insignificant in the short term. These results show that the current ecological tax structure is sufficient to reduce carbon emissions in the long term, while Pigovian taxes are effective as predicted in the theoretical framework. In this context, increasing the effectiveness of policies such as restructuring ecological taxes, developing market-based mechanisms and providing green incentives can further reduce carbon emissions at the global level.
