Abstract
Climate change represents an urgent, multi-dimensional challenge with profound ecological, social, and economic implications. Despite widespread recognition of its risks, global progress in climate action has been uneven, reflecting differences in economic capacity, governance, energy dependency, and policy ambition. This study employs a comparative cross-country analysis using the Climate Change Performance Index (CCPI) from 2021 to 2025 to examine national climate performance across greenhouse gas (GHG) emissions, renewable energy adoption, energy use, and climate policy. Focusing on 12 representative countries, including high performers, major emitters, and regional representatives, the analysis identifies leaders (e.g., Denmark, Sweden, and India), transitional economies (e.g., Brazil, Spain, and South Africa), and persistent laggards (e.g., Saudi Arabia, Russia, and China). Findings highlight that while renewable energy deployment shows consistent progress, GHG reductions and policy implementation remain insufficient, particularly among major G20 emitters. The study highlights the crucial role of standardised benchmarking tools, such as the CCPI, in fostering transparency, accountability, and international cooperation, providing actionable insights to accelerate global decarbonization and align national efforts with the Paris Agreements 1.5C goal.
