Abstract

Since the inception of the 21st century, climate policy uncertainty (CPU) has been rising in G7 countries, which can impact economic and environmental sustainability. Therefore, the present empirical study explores the influence of CPU on greenhouse gas (GHG) emissions in G7 countries. The results from the method of moment quantile regression delineate that CPU upsurges GHG emissions at the middle and upper quantiles, indicating that CPU contributes to GHG emissions if emissions are at their average (mean) level or above. The findings from robustness analysis are also in line with baseline empirical outcomes. The findings recommend initiating measures to shrink the CPU. For instance, climate policies at the federal and state levels should be in line and should be announced for a long period.

七国集团国家气候政策的不确定性和温室气体排放：环境可持续性的政策建议

进入21世纪以来，G7国家的气候政策不确定性（CPU）一直在上升，这可能影响经济和环境的可持续性。因此，本实证研究探讨了CPU对G7国家温室气体排放的影响。矩分位数回归方法的结果表明，CPU在中上分位数处增加了温室气体排放，表明当排放量处于平均水平或以上时，CPU对温室气体排放有贡献。稳健性分析的结果也与基线经验结果一致。研究结果建议采取措施缩小CPU。例如，联邦和州层面的气候政策应该保持一致，并且应该长期公布。

期刊介绍： Gondwana Research (GR) is an International Journal aimed to promote high quality research publications on all topics related to solid Earth, particularly with reference to the origin and evolution of continents, continental assemblies and their resources. GR is an "all earth science" journal with no restrictions on geological time, terrane or theme and covers a wide spectrum of topics in geosciences such as geology, geomorphology, palaeontology, structure, petrology, geochemistry, stable isotopes, geochronology, economic geology, exploration geology, engineering geology, geophysics, and environmental geology among other themes, and provides an appropriate forum to integrate studies from different disciplines and different terrains. In addition to regular articles and thematic issues, the journal invites high profile state-of-the-art reviews on thrust area topics for its column, ''GR FOCUS''. Focus articles include short biographies and photographs of the authors. Short articles (within ten printed pages) for rapid publication reporting important discoveries or innovative models of global interest will be considered under the category ''GR LETTERS''.
