The increase in carbon emissions is strongly influenced by the factor of using dirty energy which is widely used today. Control of carbon emissions absolutely must be done to avoid extreme climate change that can cause sustainable environmental damage. In overcoming this, the Government has implemented the imposition of a carbon tax through Number 7 of 2021 concerning Harmonization of Tax Regulations as well as to achieve the emission target set by 2030. This has certainly marked a paradigm shift towards the assumption that the economy is always prioritized. Therefore, this research will analyze and identify the legal politics of carbon tax regulation as the implementation of green economy policies. The formulation of the problem in this research is how is the legal politics of carbon tax regulation as the implementation of green economy policy? This study finds that the legal politics of carbon tax regulation is very enviromentalist because it prioritizes aspects of environmental sustainability, rather than the economy. In addition, it was found that there was a paradigm shift from destructive development to sustainable development.
