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.

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''.
