Introduction: Green fiscal policies are one of the sustainable public instruments available to the public sector to combat climate change. Because in the end, just as the global climate crisis has economic costs, green transformation will have fiscal repercussions. Green transformation will accelerate effectively, especially when the expenditure and revenue policies to be realized by the public sector are designed on the axis of green transformation-oriented sustainable economy. However, this is not as easy as it seems. With the public sector shaping its fiscal policies with a focus on green transformation, the transformation of the classical economic order towards a green economy will be encouraged. With the public sector's green economy-oriented sustainable fiscal policies, the private sector's investments and savings can also be directed in this direction. Aim: The aim of the study is to emphasize the importance of green fiscal policies for a sustainable green economy. Method: Literature review method was used in the study. In the light of the studies in the literature, the study was prepared in order to increase the effectiveness of green fiscal policies. Findings: Green economic transformation cannot be realized spontaneously/voluntarily by the private sector and its investments alone. Therefore, the use of fiscal policy instruments for green transformation, both due to their share in the economy and their ability to guide/incentivize, brings about a truly sustainable fiscal and economic transformation. Originality and value: This study contributes to the relationship between green economic transformation and green fiscal policies. It constitutes a scientific value as a resource for researchers.
