Global Climate Governance and International Institutions: Effectiveness, Implementation and Emerging Challenges
Abstract
Climate change is a transboundary governance problem in which scientific knowledge, international rule-making, finance, technology and national implementation are closely interdependent. This paper evaluates how international institutions shape global climate governance, how effectively the Paris architecture is translating collective goals into national action, and where institutional weaknesses continue to constrain implementation. The study adopts a qualitative documentary and comparative case-study design derived from the original synopsis, focusing on the United Nations Framework Convention on Climate Change (UNFCCC), the Intergovernmental Panel on Climate Change (IPCC), the World Bank and climate-finance mechanisms. The analysis combines official agreements, IPCC assessments, UNFCCC nationally determined contribution (NDC) synthesis reports, OECD climate-finance data, and recent institutional reports. Results show that international institutions perform four indispensable functions: agenda setting and negotiation; scientific assessment; transparency and accountability; and mobilisation of finance and technical support. The Paris Agreement has achieved near-universal participation and has progressively strengthened the procedural architecture for national commitments, transparency and global stocktaking. New NDCs submitted in 2024–2025 show improved governance quality, with high shares of Parties reporting economy-wide targets, legal or policy frameworks and explicit links to the first Global Stocktake. Yet aggregate ambition and implementation remain inadequate for a 1.5°C-consistent pathway. Current policies still imply substantially higher 2030 emissions than both unconditional and conditional NDC pathways, while climate finance, despite surpassing the earlier USD 100 billion benchmark since 2022, remains far below the scale required for mitigation, adaptation, loss and damage and technology deployment. The paper concludes that the principal institutional problem is no longer absence of global rules, but the gap between negotiated commitments and domestic execution. Strengthening climate governance therefore requires more credible implementation mechanisms, predictable finance, transparent tracking, institutional coordination and equity-sensitive support for developing countries.
