The paper examines the complex nature of legal issues associated with the implementation of climate change accountability strategies in economic policy making with a specific emphasis on the international environmental commitment versus domestic sovereignty and sustainable development latter. Particularly, it analyzes the impact of international regulatory measures, such international agreements, carbon pricing, and green finance policies, on the global decision-making processes on the economics front. Moreover, it goes through the intersection of these frameworks with the national legal systems, especially in terms of state administration restructuring to manage effective green economy and congruence of the environmental law and the economic law. This requires a critical analysis of available legal solutions, economic management philosophies and how to develop intersectoral solutions to ensure that environmental factors are incorporated into economic operations. Nevertheless, in as much as verbal promises of climate action have been on the rise, the actual introduction of a practical environmental policy tends to falter and natural resources exploitation and carbon emissions continue to soar as the world economy likewise reinvigorates its economic performance. This gap reveals the very contradiction: the development of the international green economy theory has not become an impressively large-scale change in pace. This ongoing disconnectivity of policy and ecological necessity points to the ineffectiveness of the existing measures of global climate policy and the necessity of more effective accountability regimes. The ongoing absence of accountability is not the result of the absence of initiatives, but is instead based on measurement of procedures rather than actual environmental results, which has resulted in the continued environmental degradation despite the ever-expanding control over it.
