The role of government spending on energy efficiency R&D budgets in the green transformation process: insight from the top-five countries

Unlocking the potential: How does technological innovation shape inclusive wealth? Empirical insights from top seven emerging economies

Amidst the pursuit of sustainable development and economic prosperity, there has been growing criticism directed towards traditional metrics such as GDP because of their narrow focus on societal well-being and environmental considerations. Therefore, our study shifts its focus from GDP to a more comprehensive measure of wealth, known as inclusive wealth. Our objective is to investigate how technology contributes to the advancement of inclusive wealth encompassing produced, natural, and human capital. We centred our analysis on the top seven emerging economies (E-7) and utilized data from the period of 1998-2022. Employing Fully Modified Least Squares (FMOLS), we develop four distinct models to examine the impact of technology on its various components and overall inclusive wealth. We also checked the robustness of our results by employing Cross-Sectionally Augmented Autoregressive Distributed Lag (CS-ARDL) model. Our findings reveal that technological advancement has a positive effect on each component of inclusive wealth, including produced capital, human capital and natural capital. Additionally, our results indicate a favourable impact of technological progress on overall inclusive wealth. These results emphasize the importance of incorporating technology into strategies for sustainable development and inclusive wealth.

The effect of eco-friendly and financial technologies on renewable energy growth in emerging economies

Successfully integrating renewable energy sources depends on eco-friendliness, financial technology, and economic growth (GDP). This paper examines the dynamic effect of innovative financial and green technology on renewable energy for 38 emerging economies from 2006 to 2021. Using the dynamic First-difference Generalized Method of Moments (FD-GMM) model, the analysis identifies a critical GDP threshold of 1831.772 US dollars, significant at the 1 % confidence level. Below this threshold, GDP negatively affects green energy adoption, while above it, GDP positively influences the shift to greener energy, supporting the predicted U-shaped relationship in the data. The results conclude that eco-friendly and financial technology positively and significantly influence renewable energy adoption, where the dynamics and barriers to adopting eco-friendly and financial technologies in emerging countries may differ from those in developed nations. Based on the findings, relevant energy policies have been recommended for energy stakeholders, Tech firms and decision-makers.

A review on recent biodiesel intensification process through cavitation and microwave reactors: Yield, energy, and economic analysis

The use of biodiesel as a reliable and green energy source has grown over the past few years. Biodiesel is sustainable and biodegradable because it is only made from vegetable contents and waste cooking oil. Although biodiesel has many advantages over conventional fuels, there are still a lot of technological issues that need to be addressed during the production process. The yield of biodiesel produced using conventional methods is poor and the process is time-consuming. Process enhancements like cavitation and microwave have thus been developed to address this problem. Starting with a comparison to the conventional biodiesel process, this paper has reviewed the most recent developments in the increase of mixture and transfer of heat in these two reactors. This paper examined biodiesel improvement using microwave and cavitation reactors, including biodiesel yield, by meticulously reviewing and analyzing previous works. The production of biodiesel from various raw materials using a range of catalysts, energy requirements, as well as operating factors, activation energy, and constraints also have been discussed. Additionally, the economic analysis discusses the feasibility and cost-effectiveness of implementing these technologies on a commercial scale. Overall, this review provides valuable insights into the intensification of biodiesel production using cavitation and microwave reactors while considering both the technical and economic aspects.

Greening the BRI countries through economic and political reforms

Preserving the environment and promoting sustainable development are essential objectives for a state aimed at improving the standard of living for present and future generations. The depletion of natural resources and environmental degradation are serious concerns for policymakers worldwide. However, to fulfill its role effectively, a state must have strong institutional capacity. Studies have shown that inadequate governance and weak institutional quality are associated with environmental degradation, lower economic growth, unfavorable development outcomes, and increased inequality. Economic and political reforms are necessary to overcome these issues, while the concept of institutional reforms to save the environment is novel and hardly discussed in the earlier literature, especially in the context of BRI countries. So, this study explores the impact of economic and political reforms on the environment by applying a difference-in-differences approach to the data of 45 BRI economies from 2000 to 2022. The empirical findings reveal a negative relationship between economic and political reforms on ecological footprints, emphasizing the need for institutional reform to preserve the environment in the BRI region. Institutional reforms have a significant contribution to environmental sustainability by fostering better governance, political stability, and an environment conducive to reforms-driven decision-making. These reforms can help address the environmental challenges associated with large-scale infrastructure and economic development projects like the BRI, ultimately contributing to a more sustainable future.

Moderating role of green innovation and fiscal expenditure towards achieving the Sustainable Development Agenda 2030 at provincial-level in China: policy implication from green total factor productivity

Amidst resource loss and environmental protection constraints, achieving green development necessitates enhancing green total factor productivity (GTFP) as a means of promoting rational and efficient resource allocation, thereby balancing economic growth and environmental preservation. Meanwhile, literature on the subject matter of GTFP from a sustainability viewpoint is minimal. As a result, this study employs the panel dataset from 30 provinces of China spanning the period 2005 to 2020 and utilizes the method of moments quantile regression (MMQR) developed by Machado and Santos Silva (2019) to analyze the heterogeneous role of green innovation, environmental regulations, and fiscal expenditure on GTFP. Moreover, the controlling variable for this study includes renewable energy and economic growth. Furthermore, this study investigates the heterogeneous combined impact of green innovation and fiscal expenditure (GTE*FSE) on GTFP. The findings of the MMQR reveal that green innovation has a positive impact on GTFP, while fiscal expenditure, environmental regulations, and renewable energy consumption have a negative impact. GTE*FSE has a positive and significant effect on GTFP, indicating that FSE can reinforce and increase the positive impact of GTE on GTFP in the long run. The study also reveals that economic growth has a mixed effect on GTFP, depending on the quantiles. Furthermore, environmental regulation has a significant and negative impact on GTFP, contradicting the Porter hypothesis. Likewise, the robustness of the findings is confirmed by the results of the fully modified OLS (FMOLS) and dynamic OLS (DOLS) estimations, which indicate a similar impact of the determinants on GTFP as observed in the MMQR analysis. This reinforces the validity of the findings and suggests that the observed relationships are robust to different estimation techniques. Furthermore, the findings of the Dumitrescu and Hurlin (D-H) panel causality test reveal significant bidirectional causality between renewable energy consumption and GTFP and fiscal expenditure and GTFP. Policy-makers need to channel a large chuck of their fiscal spending into green innovation so as to boost sustainability.

Empirical linkages of the construction sector, intensive energy consumption, and economic openness with chemical oxygen demand pollution

Though construction sector development and economic openness contribute to regional economic development, they have also been debated to pose some environmental challenges. Along these lines, we explored the long- and short-term connections of intensive energy consumption, economic openness, and construction sector development with the chemical oxygen demand throughout the scales of regional development of China's 30 provincial units over the 2004-2021 period. Theoretically, we contribute to the existing knowledge by incorporating chemical oxygen demand pollution, construction sector development, and economic openness to the Kaya identity's baseline framework. Empirically, we apply a series of advanced methods of panel data econometrics for robust results. Our key findings are as follows: First, we revealed a long-term stable cointegrating association among our variables of interest. Second, using the common correlated effect mean group estimator, we unfolded that the intensive energy consumption showed a chemical oxygen demand pollution reduction influence in both the long and short term, demonstrating the most substantial influence in the high regional development panel while expressing the least powerful influence the least regional development setting. Third, we unveiled that economic openness and construction sector development showed a linear chemical oxygen demand pollution enhancement influence in moderately and least developed regions. Nevertheless, both established an inverted U-shaped linkage with chemical oxygen demand pollution for the whole country as well as for high regional development data samples. Eventually, we found consistent estimates across long- and short-term investigations regarding signs of relationships; however, long-term effects remained more powerful than short-term ones. These findings would serve as factual scientific knowledge to help local as well as national governments create the optimal environmental regulations for the construction sector to achieve the sustainable development goals (SDGs), especially the Climate Action Plan (i.e., SDG-13).

Financial inclusion and environmental pollution in Türkiye: Fresh evidence from load capacity curve using AARDL method

Sustainability is an important concept for the whole world. Generally, in order to measure the sustainability of the environment, carbon dioxide emissions and ecological footprint indicators are used. However, these variables do not reflect the supply side of natural resources. Therefore, load capacity factor is an important environmental indicator for a sustainability. Environmental assessment based on the load capacity factor is more meaningful. Besides, improved access to financial services can contribute to environmental sustainability. The effect of financial inclusion on the load capacity factor in Türkiye has not been examined in the current literature. In this context, this study analyzes the impact of financial inclusion, hydropower energy consumption, and life expectancy at birth on environmental sustainability from a different perspective by focusing on load capacity factor. To this end, this study used the newly developed Augmented ARDL method to determine the cointegration relationship between the series and measure the values of the long-term coefficients. Based on the Augmented ARDL method, there is a cointegration relationship between the series. In the long run, hydropower energy consumption reduces pollution, while financial inclusion decreases load capacity factor. The effect of life expectancy at birth on pollution is not significant. Moreover, the results reveal that the load capacity curve hypothesis is valid in Türkiye. As a result, the Turkish government should promote renewable energy sources, especially hydropower energy consumption, align financial services with pollution reduction measures, and contribute to the creation of an environmentally conscious society.

Analyzing economic growth, eco-innovation, and ecological quality nexus in E-7 countries: accounting for non-linear impacts of urbanization by using a new measure of ecological quality

The rising urban population and accelerated resource consumption pose major environmental challenges. Given that around 75% of global resources are consumed in urban areas, understanding the true association between urbanization (UR) and ecological quality is necessary for better urban strategies. Alongside this, eco-innovation (ECO) can limit environmental pollution and thus, it is the cornerstone of environmental policies. On that note, this research discloses the nexus between eco-innovation, economic growth (EGR), and ecological quality by considering the non-linear effects of UR in the emerging seven (E-7) nations from 1992 to 2018. Unlike previous literature, the newly developed indicator of ecological quality (the load capacity factor (LCF)) is adopted to understand the connection between UR, eco-innovation, and ecological quality since this new comprehensive indicator is based on both biocapacity and ecological footprint (EF). In the methodology, the "Continuously Updated-Fully Modified" (CuP-FM) test is used since this method offers diverse benefits for panel data estimation by accounting for major panel data estimation issues including autocorrelation, endogeneity, heteroscedasticity, fractional integration, and cross-sectional dependence. The empirical estimates unveiled that the current levels as well as high levels of UR limit the LCF. This evidence suggests that UR in the E-7 nations expands ecological degradation. This finding contradicts the assertions of ecological modernization theory that expanding urbanization brings some ecological benefits. Similarly, economic growth alleviates ecological quality. However, eco-innovation and agricultural land (AGL) contribute to enhancing the LCF and promoting ecological quality. Further, UR and eco-innovation Granger cause the LCF. Lastly, comprehensive urban environmental strategies are discussed to promote sustainable urbanization backed by eco-innovation.

Empirical analysis of the impact of the digital economy on the green transformation of manufacturing: Evidence from China

In this study, the entropy method and the Super-SBM model with unexpected output are used at first to calculate the digital economy development index and the level of green transformation in manufacturing. Then, a range of multi-dimensional empirical methods, including fixed effects models, threshold models, and mediation models, are applied to analyze the characteristics shown by the impact of digital economy development on the green transformation of manufacturing. The research results are obtained as follows. Firstly, the digital economy contributes significantly to promoting the green transformation of manufacturing after excluding the macro-system environmental effects, conducting such robustness tests as stepwise regression and introducing instrumental variables. Secondly, there is a nonlinear relationship between the development of the digital economy and the green transformation of manufacturing with an increasing marginal effect. Lastly, it is revealed through mechanism analysis that the digital economy promotes the green transformation of manufacturing by enhancing the capabilities of green technological innovation and rationalizing industrial upgrading, with the partial mediation effects reaching 21.2% and 21.8%, respectively. Despite the contribution of digital economy to the advanced upgrading of industries, there is no mediation effect exhibited. In addition to confirming the path of achieving the green transformation of manufacturing through the digital economy, these results also guide the government on how policies can be formulated and improved to grow the digital economy and promote the green transformation of manufacturing.

Elongating the role of renewable energy and sustainable foreign direct investment on environmental degradation

Climatic variations and GHG emissions are the most debated issues of the current age economically, socially, politically and environmentally. An internationally legally binding treaty on climate change, the "Paris Agreement" is followed by G-8 countries to maintain environmental sustainability with green development. The research investigates the relationship of GHG emissions with renewable energy (RE), foreign direct investment (FDI), total population (TP), and trade (TR). The time span of 22 years is used for analytical purposes covering the period from 2000 to 2021 b y addressing the literary gap. The analytical procession found total population and trade increase GHG emissions because of its modern fundamental layers toxic human activities and polluted trade practices. The decreasing behavior toward GHG emissions has been determined by FDI and RE. The findings of this research have confirmed the long-run relationship among variables. They are evidence that the eco-innovative steps by G-8 countries significantly reduce GHG emissions directly or indirectly. Furthermore, the analytical outcomes indicate that innovative green development in renewable energy sector can reduce the GHG emissions pressure from this sector and contribute to net zero emissions. The extracting results have suggested policies for environmental practitioners and economic developers.

Capital flow and environmental quality at crossroads: designing a sustainable policy framework for the newly industrialized countries

It is extremely difficult for emerging economies to achieve the Sustainable Development Goals (SDGs), and in order to close this policy gap, a comprehensive policy framework is needed. The purpose of this research is to determine the proportional impacts of domestic and foreign capital to environmental degradation in newly industrialized nations (NICs). For this reason, panel data methodology is used to evaluate, for the years 1991 to 2018, how the ecological footprint is affected by stock market capitalization, foreign direct investment, economic growth, urbanization, and energy intensity. Using the squared terms of stock market capitalization and foreign direct investment, respectively, it is also looked at whether domestic and foreign capital may have non-linear effects on the environment. According to the empirical findings, whereas local capital growth worsens the environment, increasing international capital prevents environmental degradation. There is an inverted U-shaped link between domestic capital and environmental degradation in the event of non-linearity, but foreign capital has a monotonically declining effect on environmental degradation. The study outcomes are utilized to design a policy framework to address the objectives of SDG 7, SDG 11, and SDG 13.

Meditation for role of productive capacities and green investment on ecological footprint in BRI countries

The Belt and Road Initiative (BRI) is a development strategy with a focus on enhancing connectivity, promoting economic growth, and improving people's livelihoods. However, it has also raised concerns about its effect on the environment. This study explores the impact of productive capacities and green investment in mitigating the ecological footprint of BRI countries. The role of productive capacities on ecological footprint is very little discussed in earlier studies. This study investigates the effect of productive capacities index and green investment on ecological footprint for 42 BRI participating countries covering the time span of 2000-2018. Different methods are applied to tackle the problem of dependence of cross sections; then Lagrange multiplier bootstrap method is applied to find co-integration. The long run relationship is uncovered by "augmented mean group" (AMG) and "common correlated effects mean group" (CCEMG). The findings of the study show that both productive capacities and green investment have a significant negative impact on ecological footprint, depicting that promoting sustainable development and environmental protection is feasible through increasing productive capacities and investing in green technologies. The findings of this study have important implications for policymakers, who should focus on promoting sustainable environment by prioritizing productive capacities and green technologies.

Evaluating green productivity of the regional transport sector in South Asia considering environmental and safety constraints: the evolution from static and dynamic perspectives

The assessment of green productivity not only establishes the production ability but also involves economic, environmental, and social aspects which are the ultimate goals in achieving the sustainability. In this context, unlike the majority of previous literature, we have simultaneously considered the environmental and safety aspects to measure the static and dynamic evolution of green productivity to achieve a safe, eco-friendly, and sustainable development of the regional transport sector in South Asia. First, we proposed the super-efficiency ray-slack-based measure model with undesirable output to assess the static efficiency, which can effectively characterize weak and strong disposability relationship between desirable and undesirable outputs. Second, the biennial Malmquist-Luenberger index has been adopted to examine the dynamic efficiency, which can overcome recalculation issue once an additional time period is included in the data. Therefore, the proposed methodology provides more comprehensive, robust, and reliable insight in comparison to the conventional models. The results indicate (i) both static and dynamic efficiencies decreased during 2000-2019, implying that the transport sector in South Asia follows an unsustainable green development path at the regional level; (ii) dynamic efficiency was primarily held back by green technological innovation whereas green technical efficiency had a modest positive contribution. The policy implications suggest effective ways to improve green productivity of the transport sector in South Asia by promoting coordinated development among the transport structure, environmental and safety aspects, strengthening advance and innovative production technologies, endorsing green transportation practices, and implementing safety regulations and emission standards for the sustainable transport sector.

Mechanism of knowledge management process towards minimizing manufacturing risk under green technology implementation: an empirical assessment

Given the critical importance of green technology implementation (GTI) is important for production process improvement and an eco-friendly environment. The present study investigates the connection between GTI and the knowledge management (KM) process to minimize manufacturing risk. This research also validates that an assured combination of green implementation and KM can lead to minimizing manufacturing risk. The sample data (153) was taken from those manufacturing companies that utilize green technologies. Smart PLS 3.2.9 analyzes the relationship between certain variables of GTI and the KM process. Furthermore, fuzzy set qualitative comparative analysis (fsQCA) is used for a combined configurational approach to examine manufacturing risk minimization. The study's outcome validated that green implementation positively correlated with KM to minimize production risk. fsQCA approach, KM, and green implementation outcome indicated that production risks are minimized. This study contributes to bridging research gaps in the literature and advances understanding of the interrelationship between green implementation and KM processes to minimize manufacturing risk. In addition, research is vital to combine direct and configurational methodologies to highlight two distinct facets of green implementation and the KM process for minimizing manufacturing risk.

Evaluating the role of renewable energy and technology innovations in lowering CO2 emission: a wavelet coherence approach

Environmental sustainability is one of the most critical issues that require efficient environmental and economic policies in modern times. Advancements in renewables and green technologies contribute significantly to sustained long-term development without affecting environmental quality. Several studies focus on the association of carbon dioxide emissions (CO₂e) with economic variables. However, they ignored the impact of technological innovations and renewable energy consumption on CO₂e in developed countries. Therefore, this study examines the relationship between CO₂e, energy consumption, gross domestic product (GDP), renewable energy consumption, and technology innovations in G-7 countries by employing cross-sectionally augmented autoregressive distributed (CS-ARDL) lag and wavelet coherence techniques during 1990-2020. The results depict that GDP and renewable energy consumption are inversely related to CO₂e. A 1% increase in CO₂e will decrease GDP and renewable energy consumption by 0.459 and 0.172% in the long run and by 0.471 and 0.183% in the short run in G7 countries. Technology innovations negatively impact CO₂e in the short run while positively influencing it in the long run. Considering the advancements in green technologies in different energy-dependent and manufacturing sectors is crucial for a sustainable environment in the long run. Such initiatives ensure the effective use of energy sources by limiting CO₂e in the atmosphere. Moreover, the dynamic common correlated effects mean group model confirms the reliability and effectiveness of the CS-ARDL. The wavelet coherence approach revealed a causality relation between CO2e and technology innovation in Italy, Japan, the UK, and the USA during the study period.

Transport infrastructure, economic growth, and transport CO2 emissions nexus: Does green energy consumption in the transport sector matter?

Attaining Sustainable Development Goals (SDGs) is important to control the adverse impacts of climate change and achieve sustainable development. Among the 17 SDGs, target 13 emphasizes enhancing urgent actions to combat climate-related changes. This target is also dependent on target 7, which advocates enhancing access to cheap alternative sustainable energy. To accomplish these targets, it is vital to curb the transport CO2 emissions (TCO2) which increased by approximately 80% from 1990 to 2019. Thus, this study assesses the role of transport renewable energy consumption (TRN) in TCO2 by taking into consideration transport fossil fuel consumption (TTF) and road infrastructure (RF) from 1970 to 2019 for the United States (US) with the intention to suggest some suitable mitigation policies. Also, this study assessed the presence of transport environmental Kuznets curve (EKC) to assess the direction of transport-induced growth. The study used the Bayer-Hanck cointegration test which utilizes four different cointegration techniques to decide cointegration along with the Gradual Shift causality test which considers structural shift and fractional integration in time series data. The long-run findings of the Dynamic Ordinary Least Squares (DOLS) test, which counters endogeneity and serial correlation, revealed that the transport renewable energy use mitigates as well as Granger causes TCO2. However, transport fossil fuel usage and road infrastructure enhance TCO2. Surprisingly, the transport EKC is invalid in the case of the US, and increased growth levels are harmful to the environment. The association between TCO2 and economic growth is similar to a U-shaped curve. The Spectral Causality test revealed the growth hypothesis regarding transport fossil fuel use and economic growth connection, which suggests that policymakers should be cautious while decreasing the usage of transport fossil fuels because it may hamper economic progress. These findings call for revisiting growth strategies and increasing green energy utilization in the transport sector to mitigate transport emissions.

Asymmetric macroeconomic determinants of renewable energy consumption: do financial institutions and ICT trade matter?

This study aims to examine the asymmetric impact of financial institutions and information and communication technologies (ICT) trade on renewable energy demand in BRICS economies by using the cross-sectionally augmented nonlinear autoregressive distributed lag model. The asymmetric estimates of the financial institutions index confirm that a positive shock increases renewable energy consumption, and a negative shock reduces renewable energy consumption in BRICS economies. Similarly, the long-run asymmetric estimates attached to ICT trade are positively significant, confirming that a positive shock increases renewable energy consumption and a negative shock hurts renewable energy consumption. As far as country-wise estimates are concerned, the long-run asymmetric estimates of financial institutions are significant in Brazil, Russia, China, and South Africa. Similarly, the asymmetric estimates attached to ICT trade are significant in Russia, China, India, and South Africa. The results are asymmetric in nature, implying that negative and positive shocks have different effects on renewable energy consumption. Therefore, policymakers should consider both negative and positive shocks in financial institutions and ICT trade while devising policies regarding environmental sustainability and renewable energy consumption.

The nexus between environmental strategy and environmental performance: analyzing the roles of green product innovation and mechanistic/organic organizational structure

The relationship between environmental strategy and environmental performance has been extensively analyzed in the environmental management literature. However, this relationship is spurious due to the inconsistence outcomes, lack of intervening mechanism, and scarcity of appropriate context. This study undertakes these considerations by exploring the underlying moderation-mediation mechanism through which proactive corporate environmental strategy affects corporate environmental performance. The hypotheses of the study were empirically tested on the data gathered from 147 ISO 14001:2015 certified firms in Pakistan. The data was statistically validated and then tested with Bootstrapping method using Preacher and Hayes Process Macros. The findings of the study revealed that a proactive corporate environmental strategy predicts corporate environmental performance through green product innovation. Moreover, the moderation hypothesis of the organizational structure variable in the nexus between proactive corporate environmental strategy and green product innovation was not supported in the full sample, whereas the split sample based on organizational size indicated moderation effects in the small firm's sample. The findings of the study carry important implications for firms related to corporate environmental strategy and green product innovation strategy.

Can Renewable Energy and Export Help in Reducing Ecological Footprint of India? Empirical Evidence from Augmented ARDL Co-Integration and Dynamic ARDL Simulations

The objective of this study is to investigate the impact of exports, renewable energy, and industrialization on the ecological footprint (EF) of India over the period spanning from 1970–2017 by employing the newly developed augmented ARDL (A-ARDL) co-integration approach and the novel dynamic ARDL (D-ARDL) technique. The empirical results demonstrate that exports and renewable energy consumption reduce the EF, while industrialization intensifies the EF. More precisely, a 1% increase in export (renewable energy consumption) reduces the EF by 0.05% (0.09%). In addition, the short-run elasticity of the GDP is found to be larger than the long-run elasticity indicating the possibility of the existence of the Environmental Kuznets Curve (EKC) of the EF for India. The study indicates that the income effect and increased policy focus on renewable energy usage can be expected to reduce India’s per capita EF in the long run. Moreover, India’s export sector has been traditionally less energy intensive, which reflects in our findings of export growth leading to a reduction in EF. Based on the empirical findings, this study recommends some policy insights that may assist India to effectively reduce its ecological footprint.
