Exploring the relationship between economic development and environmental protection holds substantial theoretical value for the sustainable progress of minority regions. This paper initially analyzes the overarching mechanisms governing economic growth and climate change challenges in industrial decarbonization toward carbon neutrality. Subsequently, it conducts an empirical analysis utilizing historical economic and environmental data from five provinces to investigate the trajectory of economic development and shifts in environmental quality. The objective of this paper is to flatten the environmental Kuznets curve (EKC) in northwest minority areas, ensuring the continuous enhancement of environmental quality and green transformation in tandem with economic growth, thereby forging a low-pollution pathway for sustainable development. It is observed that an EKC characteristic exists between the economy and the environment in these regions, evolving from discoordination to primary coordination. The environment and economic development in ethnic minority areas of China are progressing slowly, and there is an urgent need for sustainable development reforms. The environment and economic development in ethnic minority areas of China from 2003 to 2022 are progressing slowly, and there is an urgent need for sustainable development reforms. During the economic development process, minimizing environmental pollution should be a fundamental prerequisite, with a focus on industrial ecological advancement, intensifying governmental environmental protection measures, and boosting green technological innovation to strive for a flattening of the EKC and advance a trajectory toward sustainable development.

The depletion of global fish stocks poses a major challenge to sustainable development, particularly in economies where marine resources are critical to livelihoods and food security. In this study, the relationship between economic development and the sustainability of fish stocks is examined using the Environmental Kuznets Curve (EKC). We use panel data from 32 economies between 2002 and 2020 and analyze the fish stock status indicator (EPI_FSS) from the Environmental Performance Index, which captures the proportion of national catches from overfished or collapsed stocks. Using a dynamic panel approach and the generalized method of moments (GMM), we investigate how the human development index (HDI) and other socio-economic factors influence changes in the state of fish stocks. Our results show a statistically significant inverted-U-shaped (∩-shaped) relationship between the HDI and the state of fish stocks, suggesting that the deterioration of fish stocks increases at lower levels of development, but improves beyond a certain threshold. In addition, higher levels of foreign direct investment (FDI), education, and research and development (R&D) spending are associated with better outcomes for fish stocks. These results suggest that while early economic growth may put pressure on marine resources, sustained investment in human capital, innovation, and global integration is critical to promoting long-term marine sustainability.

The relationship between economic progress and environmental quality remains a central focus in global sustainability discourse. This study examines the link between per capita economic growth and CO₂ emissions across 128 countries from 1996 to 2022, controlling for energy consumption, trade volume, and foreign direct investment (FDI) inflows. It also evaluates the role of governance quality—measured by regulatory quality and its volatility—while considering the globalization index as a confounding factor influencing CO₂ emissions. We test the Environmental Kuznets Curve (EKC) hypothesis, which suggests that emissions initially rise with income but decline after reaching a certain economic threshold. Our findings confirm the global presence of the EKC. The analysis further shows that trade openness, governance, and globalization significantly influence FDI inflows, with FDI, in turn, reinforcing institutional quality through improved governance and globalization indicators. However, in countries with weaker governance and regulatory frameworks, FDI tends to promote pollution-intensive industrial growth, lending support to aspects of the Pollution Haven Hypothesis (PHH). We find a significant departure in EKC explained by post-COVID governance and globalization compromises, which induced the environment towards the PHH phenomenon. These results highlight the need for context-specific policy measures that align economic development with environmental constraints. Full article

As a pivotal economic province in China, Jiangsu’s efforts in civil building energy conservation are critical to achieving the national “dual carbon” goals. This paper proposes a hybrid model that integrates wavelet transform, support vector regression (SVR), and extreme learning machine (ELM) to predict the civil building energy consumption of Jiangsu Province. Based on data from statistical yearbooks, the historical energy consumption of civil buildings is calculated. Through a grey relational analysis (GRA), the key factors influencing the civil building energy consumption are identified. The wavelet transform technique is then applied to decompose the energy consumption data into a trend component and a fluctuation component. The SVR model predicts the trend component, while the ELM model captures the fluctuation patterns. The final prediction results are generated by combining these two predictions. The results demonstrate that the hybrid model achieves superior performance with a Mean Absolute Percentage Error (MAPE) of merely 1.37%, outperforming both individual prediction methods and alternative hybrid approaches. Furthermore, we develop three prospective scenarios to analyze civil building energy consumption trends from 2023 to 2030. The analysis reveals that the observed patterns align with the Environmental Kuznets Curve (EKC). These findings provide valuable insights for provincial governments in future policy-making and energy planning. Full article

The rapid expansion of plastic waste trade has intensified environmental pressures, accelerating ecosystem degradation and climate change. We examine the long-term impacts of plastic waste imports and domestic waste production on ecological footprints and greenhouse gas emissions across 20 countries representing 70% of global plastic waste trade and 45% of world GDP. Under the Environmental Kuznets Curve (EKC) framework, we explore nonlinear interactions among economic growth, urbanization, and sustainability goals. Using a panel simultaneous equations approach, we apply Pedroni, Kao, and Westerlund cointegration tests and Fully Modified and Dynamic OLS estimators to address endogeneity and heterogeneity. Robustness checks include alternative environmental indicators and the Dumitrescu–Hurlin panel causality test. Results demonstrate a stable long-run equilibrium: plastic waste imports substantially increase ecological footprints and emissions, while progress on sustainable development goals mitigates some damage. The negative GDP squared coefficient supports the EKC hypothesis, indicating that environmental impacts rise initially with growth but decline once income exceeds a threshold. These findings highlight the need for stronger international regulations, enhanced waste management infrastructures, and circular economy strategies. Focused investment in sustainable technologies and global cooperation is essential to lower environmental costs of plastic waste trade. Full article

In this study, the relationship between economic growth and carbon emissions for the period 1968–2022 in Turkey was evaluated within the framework of the EKC (Environmental Kuznets Curve) hypothesis. In addition, the impacts of renewable energy consumption and agricultural value added on carbon emissions were analyzed using the ARDL bounds testing approach. The validity of the results was also tested using the FMOLS and DOLS methods. The findings confirmed the existence of a cointegration relationship between carbon emissions and per capita income, renewable energy consumption, and agricultural value added. Long-term analyses indicate that renewable energy consumption reduces carbon emissions, whereas growth in agricultural value added leads to an increase in emissions. In addition, it has been determined that the EKC hypothesis is valid in both the long and short terms and that increases in per capita income raise emissions up to a certain threshold and have a mitigating effect when this threshold is exceeded. The results of the short-term analysis showed that the effects of renewable energy consumption vary across periods, and that agricultural value added increases emissions in the short term. This study provides empirical evidence for Turkey by incorporating sectoral variables within the EKC framework and offers meaningful insights for policymakers regarding the environmental impacts of agricultural value added and renewable energy use in the context of a developing country. Accordingly, fiscal policy instruments such as green taxation, carbon credit trading mechanisms, and financial and agricultural subsidies should be more effectively utilized in Turkey to support structural transformation in agriculture and promote the use of clean energy, in line with the findings that suggest the need for targeted agricultural and energy policies aligned with Turkey’s SDG commitments.

This study examines the symmetric and asymmetric impacts of international trade on consumption-based carbon emissions (CBEs) in the People’s Republic of China (PRC) and the United States of America (USA) from 1990 to 2018. The analysis uses autoregressive distributed lag (ARDL) and non-linear ARDL (NARDL) methodologies to capture short- and long-run trade emissions dynamics, with economic growth, oil prices, financial development and industry value addition as control variables. The findings reveal that exports reduce CBEs, while imports increase them, across both economies in the long and short run. The asymmetric analysis highlights that a fall in exports increases CBEs in the USA but reduces them in the PRC due to differences in supply chain flexibility. The PRC demonstrates larger coefficients for trade variables, reflecting its reliance on energy-intensive imports and rapid trade growth. The error correction term shows that the PRC takes 2.64 times longer than the USA to return to equilibrium after short-run shocks, reflecting systemic rigidity. These findings challenge the Environmental Kuznets Curve (EKC) hypothesis, showing that economic growth intensifies CBEs. Robustness checks confirm the results, highlighting the need for tailored policies, including carbon border adjustments, renewable energy integration and CBE-based accounting frameworks.

The readiness of businesses to address global climate change is pivotal for achieving sustainable development. However, the dynamics of business development remain underexplored, thereby limiting the depth and scope of research in this area. To this aim, the study examines the relationship between CO₂ emissions and new business density (NBD) in the top 14 countries with the highest NBD (Hong Kong, Cyprus, New Zealand, Estonia, Malta, United Kingdom, Australia, Botswana, Iceland, Latvia, Mauritius, Norway, Sweden, and Georgia) from 2006 to 2020, within the framework of Schumpeter’s theory and the environmental Kuznets curve (EKC) hypothesis, incorporating control variables such as renewable energy consumption (REC) and population size. To estimate the relationships between variables, we employ the novel Method of Moments Quantile Regression (MMQR) approach. The findings suggest that higher NBD is associated with increased CO₂ emissions. The results support the EKC hypothesis, positing an inverted U-shaped relationship between economic growth and environmental degradation, and highlight the mitigating effects of REC and population growth on CO₂ emissions. These findings emphasize the need for countries to align labor legislation with sustainable development objectives and to promote strategies grounded in environmental principles, green economic practices, and eco-friendly technologies.

This study investigates the environmental effects of agricultural trade, renewable energy use, and economic growth in a panel of 14 selected countries for the period 2000–2021. Per capita CO₂ emissions are modeled as the dependent variable using a second-generation panel data method, the Augmented Mean Group (AMG) estimator, which accounts for cross-sectional dependence and slope heterogeneity. The analysis reveals that the share of renewable energy in total energy consumption significantly reduces carbon emissions, emphasizing the role of green energy policies in environmental improvement. In contrast, economic growth is found to increase emissions, indicating the validity of only the initial phase of the Environmental Kuznets Curve (EKC) hypothesis. Additionally, agricultural imports—and in certain cases, exports—exert upward pressure on emissions, likely due to logistics and production-related externalities embedded in the trade process. Group-specific results highlight distinct dynamics across countries: while renewable energy adoption plays a stronger role in emission mitigation in developing economies, trade composition and production technology drive environmental outcomes in developed ones. The findings underscore the need to redesign trade and energy strategies with explicit consideration of environmental externalities to align with long-term sustainability objectives. Full article

This study investigates the impact of income redistribution on carbon emissions across 154 countries from 1995 to 2023, with a particular focus on carbon inequality. Using a dynamic panel approach with two-step System GMM estimations, the analysis considers three dependent variables: average per capita emissions, top 1% per capita emissions, and the ratio of top 1% per capita emissions to national average per capita emissions. Results show that income redistribution (measured in both absolute and relative terms) significantly reduces average per capita emissions in the short term. However, redistribution has no mitigating effect on the carbon emissions of the top 1%; in some models, it is even associated with increases in elite emissions and a widening of carbon inequality. These findings suggest that while redistribution may contribute to national emission reductions, it is insufficient to curb the carbon-intensive lifestyles of the wealthiest. The analysis confirms the Environmental Kuznets Curve (EKC) hypothesis and underscores the need for complementary policy tools to more effectively address the emissions of high-emitting individuals. Overall, this study contributes to the literature by linking income redistribution with emission disparities across income groups and highlights the importance of considering distributional dynamics in climate policy design.

This study employs a critical perspective: aiming to provide a subjective and socially constructed view on the impact of corporate governance and the corporate social responsibility (CSR) choices on the environmental Kuznets curve (EKC) in terms of CO₂ emissions in Brazil. This research paper bridges the gap in the literature on the EKC by toeing a qualitative approach to what has been presented using quantitative methods, and offers insights on how the trends shape organisational policies. Furthermore, it enumerates the relationship between CSR, CO₂ choices, and EKC in the Brazilian aviation industry using one particular airline as a case study. It aims to provoke further conversation on decarbonisation. It seeks to show how EKC has been treated and to contextualise the impact of the airline sector’s CSR and corporate governance on EKC. A combination of a content analysis of the narratives of sustainability reports and a semi-structured interview with a sustainability expert from the aviation sector was used in data gathering, while critical discourse analysis (CDA) was employed in demonstrating the ideological and social contexts that shape organisational narratives and decisions in practices and governance structures that are driving CO₂ reduction strategies. The findings not only confirmed the crucial role that corporate governance plays in the implementation and monitoring of CSR practices within the sector but also shows the impact of integrating sustainability goals into corporate strategies. The policies nurtured by CSR are supported by the company’s ESG and Social Responsibility Committees. In the context of the case study, the corporate decision to transit to biofuels is contributing not only to the reduction in CO₂ emissions but is also seen as an economically viable strategy with public policies and regulatory frameworks. This paper further explains the impact of geopolitical factors and the need for international cooperation because the traditional U-shaped EKC is not supported in the context of the Brazilian aviation sector. Finally, this spurs the need for collaboration among various stakeholder companies, policymakers, and nations in the global context for sustainable development to have a lasting impact. Full article

The sustainable development of the Guanzhong Plain Urban Agglomeration (GPUA), which is a pivotal Belt and Road hub, is critical for achieving the UN’s 17 SDGs. Based on the ecological footprint (EF) model, this study innovatively constructs a three-dimensional framework integrating natural and human-made capital, using the Gini coefficient and spatiotemporal analysis to evaluate resource allocation fairness in the GPUA from 2005 to 2022. Key findings include the following: (1) EF and GDP grew continuously at annual rates of 11.43% and 11.87%, while ecological carrying capacity (EC) stabilized, pushing the GPUA toward its ecological threshold under the Environmental Kuznets Curve (EKC). Moreover, the increasing Ecological Pressure Index (EPI) shows that after 2014, the GPUA has trended toward “extremely unsafe” status. (2) The ecological carrying capacity Gini coefficient (G₁, 0.1710–0.6060) fluctuated significantly, while the economic contribution Gini coefficient (G₂, 0.1039–0.3519) showed a narrow upward trend; since 2015, the comprehensive Gini (G < 0.4) indicates that the EF aligns with its EC and economic contribution. (3) The GPUA shows fair resource allocation. Tongchuan, Baoji, and Xianyang are low economic contribution and high ecological contribution; Xi’an and Yangling Demonstration Zone are high economic contribution and low ecological contribution; Weinan is low ecological contribution and low economic contribution. These findings provide critical insights for hub urban agglomerations to achieve the 17 SDGs through fair ecological resource allocation and sustainable development. Full article

The BRICS countries (Brazil, Russia, India, China, and South Africa) are responsible for forty-two per cent of global carbon emissions. These rapidly industrializing and economically growing countries are dependent on fossil fuels, which can lead to increased emissions. This research analyses the impact of economic growth, globalization, and renewable energy (RE) use on CO₂ using a unique dataset of 155 observations and a practical model. Using panel data for 1990–2020, this study examines the relationships between CO₂ emissions, GDP, RE use, and the KOF Globalization Index based on the Environmental Kuznets Curve (EKC) theory. Cointegration, unit root test, panel data analysis, and FGLS regression methods were used in this study. The results show that economic growth and globalization increase CO₂, while RE is insufficient to reduce these effects. Moreover, it is determined that globalization has an increasing effect on CO₂. This study makes a prominent contribution to the literature by examining the combined effects of globalization and economic growth on environmental sustainability. The findings emphasize the need for sustainable energy policies in BRICS countries. Full article

The tourism industry’s explosive growth has triggered severe carbon emission issues, making enhancing tourism carbon efficiency (TCE) a pressing concern for achieving sustainable tourism development. The widespread application of artificial intelligence (AI) in tourism presents new opportunities. This study applies the Environmental Kuznets Curve (EKC) theory to examine the pathways and mechanisms of AI’s impact on TCE, with a focus on China. The findings reveal that AI significantly enhances TCE, where improvements in tourism labor productivity, the rationalization of the tourism industry structure, and advancements in tourism technology are the key channel mechanisms. Heterogeneity tests indicate that AI substantially boosts TCE in eastern developed regions and areas with deficient tourism resource endowments. Furthermore, AI exhibits significant spatial spillover effects, enhancing both local and neighboring regions’ TCE. These insights provide crucial policy implications for utilizing AI to promote China’s sustainable tourism industry. Full article

This study explores the dynamic relationship between economic growth, technological innovation, and $C{O}_2$ emissions in BRICS nations, integrating the Environmental Kuznets Curve (EKC) and Innovation Claudia Curve (ICC) frameworks. Using a panel ARDL approach on data from 1991 to 2023, we investigate the long-run and short-run interactions between GDP, renewable energy consumption (RENC), foreign direct investment (FDI), urbanization (URB), and patent applications (PAs) in shaping environmental outcomes. The findings confirm the EKC hypothesis, revealing an N-shaped relationship between GDP and emissions, indicating that while economic growth initially leads to higher $C{O}_2$ emissions, this trend reverses at a critical threshold before a secondary increase occurs at higher income levels. The ICC framework identifies a cubic relationship between innovation and emissions, where technological advancements initially drive higher emissions before contributing to sustainability at later stages, though an excessive scale of innovation may reintroduce environmental pressures. RENC is found to significantly mitigate emissions, while URB and FDI display dual and context-dependent effects, highlighting the multidimensionality of sustainable transitions in emerging economies. These results underscore the importance of targeted policy interventions, such as scaling renewable energy infrastructure, promoting green innovation, guiding urban expansion, and aligning FDI with environmental objectives.
