GLOBAL CLIMATE GOVERNANCE AND MITIGATION STRATEGIES: THE ROLE OF THE UNITED NATIONS IN FACILITATING COOPERATION

Climate change had emerged as a global governance challenge that required coordinated responses among states and international organizations. This study examined the role and effectiveness of international organizations in addressing climate change, with emphasis on climate financing, policy coordination, technical assistance, capacity building, mitigation, adaptation and international cooperation. The study adopted a descriptive research design and relied on secondary data obtained through documentary review. Data were drawn from peer-reviewed journal articles, scholarly books, international agreements, policy documents, institutional reports, climate assessments and publications on climate governance. Purposively selected documents were analyzed using thematic and qualitative content analysis, with evidence coded, categorized and synthesized according to the research questions. Institutional theory was adopted as theoretical framework.The findings revealed that international organizations had made contributions to climate action through the mobilization and allocation of climate finance, coordination of climate policies and commitments, provision of technical assistance, capacity building, mitigation and adaptation support, technology and knowledge cooperation, and facilitation of climate negotiations. However, their contributions had been constrained by institutional fragmentation, inadequate and difficult-to-access climate finance, divergent national interests, weak administrative and technical capacity, poor inter-institutional coordination, gaps between international commitments and domestic implementation, technology and knowledge deficits, and the economic and institutional vulnerabilities of developing countries, particularly African states. The study further found that international climate programmes and agreements did not necessarily constitute effectiveness; rather, effectiveness was reflected in measurable mitigation, adaptation, resilience and implementation outcomes. Accountability, transparency, monitoring and reporting were also identified as essential for assessing progress and strengthening implementation. The study concluded that international organizations had remained central to climate governance, but their effectiveness had depended on translating international commitments, financial resources, technical knowledge and institutional mechanisms into sustained climate action. The study recommended stronger institutional coordination, improved accessibility and targeting of climate finance, sustained capacity building, appropriate technology and knowledge transfer, and stronger accountability and monitoring mechanisms, particularly in developing countries and Africa.
