An Evaluation of the Convergence of Six Different Environmental Sustainable Development Goals in OECD Countries

The aim of this study is to analyze the convergence of the six Sustainable Development Goals (SDGs) closely related to the environment, out of the 17 SDGs targeted to be achieved by all countries by 2030 by the United Nations, in the context of OECD countries. To this end, the convergence of the general SDG index and SDG 6, 7, 12, 13, 14, and 15, which are related to the environment, has been analyzed between 2000 and 2023. A recently- introduced structural unit root test has been used in the study. The study concluded that OECD countries with the same convergence/divergence results and expectations for the SDG Index, SDG 6, SDG 7, SDG 12, SDG 13, SDG 14, and SDG 15 should monitor their environmental policies, while countries with different expectations should update their environmental policies.
