The Securitization Of Climate Change In EU And The Global Climate Governance

After the Cold War,with the changes in the international environment,the object of international security research has gradually expanded from the traditional security field to the non-traditional security field.Factors such as environment,economy,and finance have been put into the international political agenda.As the problem of climate change becomes more and more serious,the concept of climate security appears.In 2007,the United Nations Security Council launched the first debate on the relationship between climate,energy and security,which opened the prelude of securitizing climate change.However,for the choice of climate change securitization,different actors have different attitudes.Compared with countries such as China and the United States,EU is an active actor in the field of climate change security,and the first to integrate climate change into its overall security strategy.In the non-traditional security theory,securitization theory by the Copenhagen School provides new concepts and theoretical support for studying security issues in the new situation.According to the securitization theory,securitization behavior is a construction process of "speech-act ".The actor highlights the existential threat of the issue through speech,which makes the audience recognize the existential logic and then agree to take unconventional measures to deal with the threat,forming a new norm.The process of climate change securitization in the EU follows the basic logic of securitization theory.However,due to the lack of securitization theory by the Copenhagen school in analyzing the background and practice of securitization behavior,this dissertation attempts to make a systematic study of securitization of climate change in EU based on securitization theory and practical factors.This dissertation aims to answer the core question which is the process and causes of EU's climate change securitization.And then this dissertation continues to analyze the impact of EU's climate change securitization on the current global climate governance.First of all,this dissertation clarifies the concept,background and development of climate change securitization on the basis of combing the concept of security and securitization theory.Secondly,this dissertation sorts out the important reports,actions and security strategic policies of the EU and its member states,and then demonstrates the view that EU has promoting climate change securitization at the member states and the overall level through empirical analysis.On this basis,this dissertation takes the factors that affect the behavior of actors in the securitization theory as the basic framework,combined with various practical factors in the EU,to sum up the factors that affect the climate change securitization of EU.Finally,this dissertation discusses the positive and negative impacts of EU climate change securitization on global climate governance.The conclusion of this dissertation is that the process of EU's climate change securitization is completed in three stages,and the factors affecting EU's climate change securitization are mainly divided into external and internal aspects.External factors include the setting of international agenda and the need of EU to form its global governance leadership.Internal factors include the threat of climate change to the EU,the EU's awareness of the threat and its own defense capability,and the EU's internal crisis.The positive impact of EU's climate change securitization on global climate governance lies in that,on the one hand,it promotes global climate governance by promoting the development of its internal climate governance policies,on the other hand,it promotes climate governance by guiding the securitization of global climate change.The negative effects include that excessive security affects the process of global climate governance and securitization might destroys the principle of fairness in climate governance.
