Environmental fiscal policy and carbon emissions in Turkey: evidence from cointegration and causality analysis with structural breaks

Environmental degradation, a critical issue in academic literature, arises from multiple factors including increased carbon emissions, urbanization, industrialization, mass production, and extensive use of non-renewable energy sources. These factors notably impact sustainable economic growth and environmental quality. Globally, efforts are directed towards optimizing carbon emissions to minimize their adverse effects. This necessitates effective environmental policies. This study examines the effectiveness of Turkey's environmental policy using cointegration and causality tests that account for structural breaks. The analysis utilizes data from 1990 to 2020, the most comprehensive dataset for Turkey to date. Findings indicate that Turkey's environmental policy is effective in reducing carbon emissions, highlighting a need for policy reassessment.
