This study aims to examine the relationship between green investment (GI), fiscal policy (FP), environmental tax (ET), energy price (EP), natural resource rent (NRR), and the consumption of clean energy (CE) to promote sustainable development in Cambodia for the period 1990–2021. The study implemented linear and nonlinear frameworks to document explanatory variables’ potential effects on clean energy consumption in the long and short run. The research findings demonstrate a robust and favorable connection between GI, FP, ET and CE, both in the long term and short term. An augmentation in GI results in the establishment of sustainable growth in the utilization of renewable energy, thereby underscoring the significance of green initiatives in advancing clean energy technologies. Fiscal policies, encompassing tax incentives and subsidies, exert a substantial and enduring influence on expanding renewable energy sources. Implementing environmental taxes catalyzes the demand for clean energy, significantly preserving the environment and promoting sustainable energy practices. Furthermore, the study illuminates the inverse correlation between oil prices and REC. Adopting renewable energy sources may face obstacles in the form of elevated oil prices, as conventional energy sources maintain a cost advantage. On the contrary, decreased oil prices and natural resource rent incentivize transitioning towards using clean energy. Countries that heavily depend on the export of natural resources may display a reduced inclination to invest in renewable energy, commonly called the “resource curse” phenomenon. This study provides valuable insights into the intricate interplay of multiple factors that influence renewable energy consumption and contribute to sustainable development. Policymakers, businesses, and researchers can employ these findings to develop productive strategies that advance the inclusion of clean energy, tackle potential challenges, and cultivate a more environmentally friendly and sustainable future.

This research endeavors to investigate the impacts of information and communication technology, green technological innovation, and environmental tax on the attainment of ecological sustainability with advanced panel date estimation for 2001–2019. The results of this study demonstrate a noteworthy inverse relationship between information and communication technology and ecological footprint, suggesting that progress in ICT has the potential to yield positive consequences in terms of ecological restoration and the promotion of environmental sustainability. Furthermore, this study underscores the significance of GTI in mitigating carbon emissions and effectively addressing environmental challenges. The findings indicate that the incorporation of environmentally sustainable technology can yield favorable ecological consequences and make significant contributions towards the attainment of worldwide climate targets. Nevertheless, the study highlights the importance of considering potential rebound effects. It underscores the imperative for ongoing research and the implementation of comprehensive policies within the realm of environmentally sustainable technology. Moreover, the present study elucidates the favorable ramifications of GF on ecological sustainability, underscoring its pivotal contribution in curtailing carbon emissions, augmenting environmental benchmarks, and facilitating the ecological footprint. Enhancing the utilization of green finance, making adjustments to national regulatory frameworks, and achieving harmonization of public financial incentives to bolster sustainable development are important. Additionally, the study posits that the incorporation of ET can catalyze businesses and individuals to embrace environmentally friendly energy sources and sustainable practices, thereby fostering positive outcomes for the environment. The study offers significant insights into the contributions of information and communication technology, green technology innovation, and environmental technology to advancing ecological sustainability. It emphasizes the need for collaborative endeavors among academia, industry, and government to cultivate a supportive ecosystem for sustainable development.

This research investigates the intricate relationship between financial openness, natural resources, and carbon neutrality in the N-11 countries. It provides insights into how environmental tax and innovation can drive carbon neutrality in these nations, thus advancing our understanding of the nexus among financial openness, natural resources, and carbon neutrality. The study aims to offer policymakers perspectives on formulating policies to foster sustainable economic development and environmental conservation in the N-11 nations. The discourse highlights the environmental implications of foreign direct investment (FDI) and trade openness, revealing a complex interplay between economic development, technological innovation, and environmental sustainability. While FDI can facilitate technological transfers and managerial advancements that enhance resource efficiency and promote environmentally friendly practices, its environmental impact varies based on regulatory frameworks and enforcement mechanisms. In countries with weak environmental regulations, FDI may lead to negative outcomes such as pollution hotspots, resource depletion, and ecosystem degradation. Similarly, trade openness can exacerbate environmental degradation through increased production, energy consumption, and waste generation. However, both FDI and trade openness can contribute positively to environmental sustainability when coupled with effective environmental policies, investment in green technology, and the promotion of sustainable practices. Thus, policymakers must strike a balance between economic development and environmental protection by implementing stringent environmental regulations, promoting clean technology transfer, and fostering sustainable development practices domestically and internationally. This research offers valuable insights for policymakers aiming to navigate the complexities of achieving carbon neutrality while ensuring sustainable economic growth in the N-11 countries.

The rapid technological and economic growth in CIVETS countries poses challenges to environmental sustainability. This study explores the intricate relationships between Information and Communication Technology (ICT), natural resource usage, and green innovation in these economies. Employing advanced statistical models uncovers long-term and short-term patterns, providing valuable insights for policymakers, stakeholders, and scholars. Key findings reveal that ICT diffusion can potentially reduce carbon emissions, while natural resource rent is linked to increased ecological footprints. Conversely, green technological innovation is promising in alleviating environmental degradation. The study underscores the importance of comprehensive policies integrating ICT diffusion, sustainable resource management, and green innovation. To achieve environmental sustainability, the study recommends responsible natural resource extraction, fiscal incentives for green innovation, digital tools for environmental monitoring, and international collaboration. Public awareness and sustainable urbanization practices guided by ICT are also crucial. These insights help policymakers balance economic development with ecological preservation in the CIVETS nations.
