Abstract

This study examines the complex relationship between environmental degradation, energy-related uncertainty (EUI), climate policy uncertainty (CPU), and energy consumption diversification (ECD) in the United States from January 2001 to September 2022. Employing novel and robust econometric methods, including the Bootstrap ARDL Bounds test with smooth and sharp structural breaks, the Toda-Yamamoto causality test with a Fourier function, and partial wavelet coherency analysis, the study reveals a surprising negative relationship between both EUI and CPU with CO₂ emissions which suggests that uncertainties surrounding energy and climate policies may incentivize actors to adopt cleaner technologies and prioritize emission reduction strategies. However, the study also identifies a positive relationship between ECD and CO₂ emissions, highlighting the need for strategic diversification prioritizing renewable and low-carbon sources. These findings emphasize the critical role of clear, consistent, and sustained climate policies in fostering clean energy investment and mitigating environmental degradation.

不确定性与多样化：分析能源相关政策和气候政策的不确定性对美国环境退化的影响

本研究考察了2001年1月至2022年9月期间美国环境退化、能源相关不确定性（EUI）、气候政策不确定性（CPU）和能源消费多样化（ECD）之间的复杂关系。采用新颖而稳健的计量经济学方法，包括平滑和尖锐结构断裂的Bootstrap ARDL边界检验、傅立叶函数的Toda-Yamamoto因果检验和部分小波相干性分析，该研究揭示了EUI和CPU与二氧化碳排放之间令人惊讶的负相关关系，这表明围绕能源和气候政策的不确定性可能激励参与者采用更清洁的技术并优先考虑减排战略。然而，该研究还确定了ECD与二氧化碳排放之间的正相关关系，强调了战略多样化的必要性，优先考虑可再生能源和低碳能源。这些发现强调了明确、一致和持续的气候政策在促进清洁能源投资和缓解环境退化方面的关键作用。

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''.
