過多溫室氣體的排放帶來了許多災害，世界各國針對溫室氣體排放議題都嚴陣以待，不僅簽署了各種條約，更是通過了相關法規，在迫切需要進行改變的環境下，不管是使用再生能源或是進行相關技術創新等方式，都讓政府投入了一定的心力。而歐盟議會曾以壓倒性的票數通過巴黎協定，並提出歐洲氣候法等法案來達成氣候中和等目標，可見歐洲國家在促進永續上不餘遺力，然而各國在溫室氣體治理的績效是為何是本文關注的重點，因此本研究以2015年至2020年間的27個歐洲國家為研究對象，探討其在經濟發展和溫室氣體治理的效率。本研究最大的貢獻為透過可以處理負值的模型為歐盟各國在溫室氣體投入的經費進行了評估，觀察期投入是否具備治理的績效。研究揭示了其中14個國家的總效率高於平均水平，顯示了這些國家在經濟發展、溫室氣體排放及治理效率方面的優秀表現。特別是比利時、保加利亞、愛沙尼亞等國在六年間始終保持高效率，成為其他國家的學習榜樣。此外，研究還指出，雖然部分國家如奧地利、比利時的表現在某些年份波動較大，但從長遠來看，大部分國家的溫室氣體治理效率呈現上升趨勢。
在生產階段，各國能源消費和勞動力效率均顯示出逐年改善的趨勢。反映出各國在溫室氣體治理方面的顯著努力及投入。然而，效率表現在奧地利、比利時等國之間仍存在顯著差異，顯示出進一步優化空間。
政府在環境保護支出的效率顯著提高，尤其在減排效率上，顯示歐洲各國在減少溫室氣體排放方面取得了重大進步。這對於應對全球氣候變化及實現國際氣候協定目標具有關鍵意義。總體來看，歐洲國家在氣候治理方面的持續努力，有效地提高了治理階段的整體效率，為氣候變化挑戰提供了積極回應。

The excessive emission of greenhouse gases has led to numerous disasters, and countries around the world are taking serious precautions against greenhouse gas emissions. Not only have various treaties been signed, but relevant regulations have also been passed. In an environment that urgently needs change, governments are investing considerable effort, whether by using renewable energy or through technological innovation. This study focuses on 27 European countries from 2015 to 2020, examining their efficiency in economic development and greenhouse gas management. The major contribution of this research is the evaluation of the funds invested in greenhouse gas reduction by the EU countries using a model that can handle negative values, observing whether these investments have governance performance. The study reveals that 14 countries have an overall efficiency above the average level, demonstrating their excellent performance in economic development, greenhouse gas emissions, and management efficiency. Particularly, Belgium, Bulgaria, and Estonia have consistently maintained high efficiency over six years, serving as role models for other countries. Moreover, the study points out that although some countries like Austria and Belgium have shown significant fluctuations in certain years, most countries' greenhouse gas management efficiency has shown an upward trend over time.

During the production phase, the energy consumption and labor efficiency of the countries have shown a yearly improvement trend, reflecting the significant efforts and investments in greenhouse gas management. However, there are still significant differences in efficiency performance between countries like Austria and Belgium, indicating room for further optimization. The efficiency of government spending on environmental protection, especially in emission reduction efficiency, has significantly increased, showing that European countries have made substantial progress in reducing greenhouse gas emissions. This is crucial for addressing global climate change and achieving the goals of international climate agreements. Overall, the sustained efforts of European countries in climate governance have effectively improved the overall efficiency of the governance phase, providing a positive response to the challenges of climate change.
