The Impact of Diplomatic Networks on International Climate Change Agreements

Thesis Abstract

The escalating urgency of climate change necessitates effective international cooperation, where diplomatic networks play a pivotal role in shaping, negotiating, and implementing climate agreements. This study investigates the influence of diplomatic networks on the success and efficacy of international climate change accords, addressing the persistent challenge of fostering global consensus amidst divergent national interests. The primary aim is to empirically assess how the structural characteristics and operational dynamics of diplomatic networks impact key outcomes within climate negotiations, such as treaty commitments, compliance levels, and adaptive capacities. The specific objectives include (1) examining the composition and strength of diplomatic networks involved in climate negotiations; (2) analyzing the correlation between network centrality and treaty success; and (3) exploring the role of cross-network linkages in facilitating consensus-building and resource sharing among states. Employing a mixed-methods research design, the study integrates quantitative social network analysis (SNA) with qualitative thematic analysis to capture both structural and contextual dimensions of diplomatic interactions. The quantitative component involves collecting data from an official database of diplomatic interactions, treaty negotiation records, and membership rosters from international climate forums such as the United Nations Framework Convention on Climate Change (UNFCCC) over the period 2005–2022. A sample size of 250 diplomatic actors, including state representatives, international organizations, and non-governmental diplomatic entities, is purposively selected based on their active involvement in climate negotiations. Social network measures—such as degree, betweenness, and eigenvector centrality—are computed using UCINET, while regression analysis (specifically, multiple linear regression) is used to test hypotheses regarding network centrality and treaty success metrics. The qualitative component involves conducting in-depth interviews with 30 senior diplomats and climate negotiators to uncover perceptions of network influence, trust, and information flow within diplomatic circles. Thematic analysis, facilitated by NVivo, is employed to interpret interview transcripts, providing contextual insights into the quantitative findings. Ethical considerations adhere to institutional protocols, emphasizing confidentiality and voluntary participation. Expected findings suggest that diplomatic network centrality significantly correlates with treaty success, enhanced compliance, and resource mobilization. Moreover, the presence of strong cross-network linkages facilitates consensus, reduces negotiation deadlock, and promotes innovative policy solutions. The study anticipates that regions with dense and well-connected diplomatic networks—especially those integrating non-state actors—demonstrate higher negotiation effectiveness and climate action outcomes. The research contributes to scholarly understanding by empirically demonstrating the mechanisms through which diplomatic networks influence international environmental policy, filling gaps in the literature regarding structural network effects on climate negotiations. It also refines theoretical perspectives by integrating social network theory with constructivist and institutionalist frameworks, such as Robert Keohane’s regimes and Emanuel Adler’s constructivism, to explain the dynamic and relational nature of diplomatic influence. The main conclusion emphasizes that strengthening diplomatic networks through targeted capacity building, increased cross-sector engagement, and fostering trust among actors can significantly enhance the effectiveness of global climate agreements. The study recommends policy strategies aimed at promoting inclusivity in diplomatic networks, leveraging digital communication platforms to expand reach, and institutionalizing mechanisms for continuous network assessment and optimization. Further research is suggested to explore longitudinal impacts of network evolution and the role of emerging diplomatic actors in shaping future climate governance.
