Achieving environmental sustainability is not solely a technological or scientific challenge—it is deeply rooted in systemic change. Policy, governance, economics & climate finance explores the frameworks necessary to align economic incentives, regulatory tools, and institutional actions with climate goals. Carbon pricing, green bonds, environmental taxation, and subsidy reform are among the financial mechanisms reshaping market behavior. At the same time, climate justice and equity concerns push for inclusive policy designs that uplift vulnerable populations. As international treaties evolve and national action plans expand, transparency, accountability, and stakeholder participation become key indicators of effective governance. The integration of Policy, Governance, Economics & Climate Finance is shaping a multidimensional approach to climate action.
