隨著氣候變遷，對地球生態環境造成甚大的影響，《聯合國氣候變化綱要公約(United Nations Climate Framework Convention, UNFCCC)》生效後，從1995年即在柏林召開的締約國大會COP1，直至2015年巴黎舉行的COP21，甚至即將在德國波昂舉辦的2017年COP23，不斷探討面對氣候變化，人類該如何因應及避免氣候變遷的加劇，呼籲各國應擔負溫室氣體減量的責任，如《京都議定書(Kyoto Protocol)》與《巴黎協議(Paris Agreement)》，要求締約國定期制定排放減量目標，以徹底執行實質減量。
根據德國看守協會(Germanwatch)每年出版的報告顯示，德國溫室氣體排放量總噸數為全球前十名，亦為歐盟內為最大排放量國，但在氣候變遷表現指數(Climate Change Performance Index, CCPI)的排名卻也為十大排放國之首，德國這世界工業龍頭在工業發展的同時也為溫室氣體排放減量努力。為了實現1997年的《京都議定書》的約定，德國亦制定了許多關於溫室氣體減量的法制，如德國在2004年即通過《溫室氣體排放交易法（Treibhausgas-Emissionshandelsgesetz, TEHG）》、《德國聯邦分配法令(Zuteilungsgesetz, ZuG)》等。本文透過對文獻的整理、歸納和分析，先說明德國歷年來的溫室氣體減量目標，再以資料庫中溫室氣體排放的數據呈現至目前為止的溫室氣體減量狀況。並以德國聯邦之官方網站和官方新聞稿為資料蒐集對象，研究達成溫室氣體減量目標的政策演進，進一步探討溫室氣體排放相關法制的重點內容，以究明德國減少溫室氣體排放量的關鍵，希望藉由本研究提供我國溫室氣體減排可行的參考對策。

With the climate change, it has a great impact to the Earth's ecological environment. After the United Nations Climate Framework Convention (UNFCCC) entering into force, from the Conference of the COP1 held in Berlin from 1995 to 2015, COP21 held in Paris, or even COP23 to be held in Bonn, Germany in 2017, continue to explore how to cope with climate change and how human beings should adjust and avoid climate change to become intensified. Moreover, it appeals countries to bear the responsibility of greenhouse gas reduction, such as the Kyoto Protocol and the Paris Agreement. In order to implement substantial reductions, these contracts require contracting party to draw up greenhouse gas emission reduction targets, and to force them to reduce their emissions.
According to reports released annually by the Germanwatch, the total greenhouse gas emissions in Germany is the top 10 in the world and the largest in the EU. However, Germany is also the top ten in the climate change performance index (CCPI) Ranking. Germany as the world's industrial leaders, not only develops in industrial sector, but also devotes to greenhouse gas emissions reduction. In order to fulfill the requirement in Kyoto Protocol in 1997, Germany has also prescribed a series of laws on greenhouse gas reductions, such as Germany in 2004 through the Greenhouse Gas Emission Trading Act (Treibhausgas-Emissionshandelsgesetz, TEHG), the German Federal Allocation Act (Zuteilungsgesetz, ZuG).
This paper demonstrates the German greenhouse gas emission targets over the years and then describes emission status in Germany. Furthermore, it investigates the development of policies by collecting announced policies and press release on German federal’s official website. Forwardly, it discusses the focal points from German greenhouse gas emission reduction related acts. For having extensive knowledge on the key emission reduction movement which Germany conducted, and providing Taiwan the feasible strategies on greenhouse gas emission reduction for reference.
