Climate Change has immensely evolved as a security challenge for most of the vulnerable communities in the world which is redesigning the global governance concerns for international cooperation. The increasing tendency of climate induced migration, scarcity of resources, food security, forced displacement, and socio-economic unrest has raised the issue of climate security to a core agenda within global context. In response, the United National Framework Convention on Climate Change (UNFCCC) and the Conference of Parties (COP) has provided the official platforms for states to negotiate collective action to mitigate all the problems including climate finance, adaptation and loss and damage. Although successive COP negotiations have elevated the international commitments to strengthen the prospective framework for climate action, yet many climate vulnerable developing countries continue the same deprivation of huge gaps between global commitments and implementation mechanism is very poor. Pakistan demonstrates the convincing case to promote climate diplomacy as it contributes less than 1% in the greenhouse gas emissions yet the highly vulnerable state to face climate induced disasters which become a security threat because of the lack of international commitments. This paper examines Pakistan's involvement to understand how climate governance shapes climate security with the COP mechanism. The backdrop of this argument is that Pakistan has increasingly redefined climate change from an environmental issue to a multidimensional security challenge which is affecting all strands of life including human security, economic deprivation, water scarcity, food security and more importantly a huge threat to sustainable development. The study theoretically adopted eclectic farmwork that assimilate perception from Liberal Institutionalism and Constructivism. Liberal institutionalism gives a framework to reduce global problems like Climate Change through international institutions, which facilitate the process of cooperation through rules, norms and multilateral agreements, while constructivism explains how norms, identities and discourse if climate security shape state behaviour and diplomatic commitments. The COP process projects institutional mechanisms which promote cooperation while the concept of climate security as traditional security thinking by recognizing climate change as a threat, producing these perspectives together allow a more comprehensive taking on international institutional engagements, persistent change, and state’s policy responses. Methodologically, the research enlists qualitative research thematically analysed though secondary sources which utilize a documentary analysis and archival analysis. Documentary analysis sources include Pakistan’s Nationally Determined Contribution (NDCs), National Climate Change Policy, and United Nations Development programme (UNDP) .While the archival analysis relies on UNFCC records, COP agreements, and official statements delivered by Pakistani Officials on successive COP meetings to trace the evolution of Pakistan’s Climate diplomacy and policy commitments. The research finds that as Pakistan has efficiently targeted recognition of climate vulnerability and grabbed international attention to adapt the measures such as climate financing, governance issues and dependency on financial support by the outer world are the obstacles to meet the COP commitments. This paper asserts that efficacy of global climate governance has mainly two drivers, one is the strengthening of the international institutional framework and second is the translating the global norms into coherent climate strategies by the vulnerable states.
