氣候變遷乃人類目前所面臨的一項全球性問題。歐盟針對氣候變遷如何回應，採取哪些政策與行動，其特徵與成效又如何？這是本文關心的一項重點，其他議題包括：歐盟氣候變遷政策如何形成，有何理念與目標、法源依據、組織架構、決策流程、政策措施、國際談判，以及有何意涵與影響。氣候變遷乃一跨部門與超國界的議題，歐盟超國家氣候變遷政策因此得提供其他國家、區域性與國際性組織，從事氣候變遷國際合作的比較參考，頗具意義。 Climate change is currently a global issue faced by human beings. Combating climate change is a top priority for the EU policy. In 2007 the EU endorsed an integrated approach to climate and energy policy and committed to transforming the EU into a highly energy-efficient, low Carbon economy. The EU has long been a driving force in international negotiations for larger global actions to structure an effective global climate regime. This paper focuses primarily on examining climate change law, strategy and practices in the EU. The following core issues are exploited: What is the concept and impacts of climate change on the EU? What is the legal framework, decision-making procedure, institutional structure of the EU’s climate change policy? To what extent the EU’s climate change policy is influenced by the European Council and the EU’s foreign policy under the Lisbon Treaty? What is the strategy adopted by EU at the international negotiations on climate change? And what’s the significance and impacts of the EU model of climate change policy on third countries and international organizations?
