Policy Stringency on Climate Change (PSCC) Quantification Framework. This figure illustrates the expanded structure used for quantifying the Policy Stringency on Climate Change (PSCC) score based on four main pillars: Policy Measures, Policy Objectives, Implementation, and Spatial Scale Factor. Following the IPCC AR6 framework, mitigation (green) and adaptation (orange) dimensions are each broken down into specific sub-dimensions (e.g., Energy Systems, Land and Ocean Ecosystems). Each sub-dimension within mitigation and adaptation is evaluated based on the rigor of policy measures and policy objectives. Implementation (blue) is assessed separately across three levels: Stringent, Consistent, and Permissive. Spatial Scale Factor (yellow) incorporates geographic categories (Regional, Universal, Provincial, Prefecture) and is derived using Principal Component Analysis (PCA) to adjust PSCC based on policy impact breadth.
