Summary: This study utilized panel data estimators to explore the association between factors such as economic complexity, human capital, renewable energy generation, urbanization, economic growth, export quality, trade and ecological footprint. The long-run estimates revealed that economic complexity, economic growth, export quality, trade and urbanization increase ecological footprint, while human capital and renewable energy generation help to mitigate ecological footprint. The conclusion suggests that investing in more renewable energy generation and efficient use of human capital can improve economic complexity, export quality, and the environment in both developed and developing countries.

Summary: This article aims to approach the research related to the environmental Kuznets curve from a new and more holistic perspective. The validity of the curve is tested using ecological footprint as the dependent variable and economic complexity index, per capita income, and trade-to-GDP ratio as the independent variables. The analysis confirms the validity of the curve for the top nine industrialized countries and shows that economic complexity decreases ecological footprint. Causality tests reveal a causal relationship from all the independent variables to ecological footprint.

Summary: This study aims to investigate the impact of economic complexity on ecological footprint by considering the N-shaped environmental Kuznets curve (EKzC) hypothesis. Two models are designed for a sample of eighty-five countries from 2001 to 2020. The findings do not support the N-shaped EKzC hypothesis in model 1, but confirm it in all income groups except for the upper-middle-income countries in model 2. Moreover, a negative relationship between renewable energy consumption and the ecological footprint is found, highlighting the importance of promoting greener energy to combat global warming.

Summary: Debates on the relationship between inclusive growth and sustainable development have been increasing in recent years. This study analyzed data from 11 developing countries in 2008 and 2018, finding that Turkey and China performed the best in terms of inclusive growth, while Pakistan and Indonesia performed the worst. In terms of sustainable development, Brazil and Pakistan ranked the lowest, while Cambodia and Thailand ranked the highest. The study also revealed a negative correlation between social inclusion and poverty with life-threatening factors of sustainable development, as well as a positive correlation between unsatisfactory medical services, education, state transparency in inclusive growth and poverty and its consequences in sustainable development. Therefore, the study suggests that developing countries should prioritize inclusive growth as a policy strategy to enhance sustainable development.

Summary: This study analyzes the impact of economic instability and geopolitical risk on traditional non-renewable energy and precious metals markets. The results show a higher level of connectedness during the Russia-Ukrainian conflict. Geopolitical risk, financial instability, and oil return are net transmitters of shocks, while gold, gas, and silver are net receivers. Gold serves as a stable asset and provides a hedge against geopolitical risk and financial instability. The findings highlight the importance of considering geopolitical risk and financial instability in investment and production decisions in metals, precious, and energy markets.

Summary: This paper investigates the relationship among the climate change index, green financial assets, renewable energy markets, and geopolitical risk index using Quantile Vector Autoregressive (QVAR) and wavelet coherence (WC) methods. The study finds that the Total connectedness index (TCI) varies depending on the quantile, with the highest TCI originating in the upper quantile. The TCI decreases after the second wave of COVID19 but increases during the first 100 days of the Russia-Ukraine conflict. Furthermore, the results show that Geopolitical risk (GPR) acts as a net transmitter of the climate change index during the Russian invasion of Ukraine. The green bond and clean energy markets are negatively correlated with the GPR at the extreme 10th and 90th quantiles. The wavelet coherence analysis confirms the QVAR results, suggesting that the climate change market can serve as a safe haven against GPR during the Russian invasion. The study emphasizes the importance of the climate change index, green financial assets, and clean energy in financial markets and their role in international peace and reducing geopolitical risk.

Summary: The recent progress report on the Sustainable Development Goals (SDG) 2022 highlights the existence of a policy gap at the global level in achieving SDG 7. The Energy Transition is identified as a possible means to achieve this objective. However, the geopolitical risks associated with global interconnectedness might impede the energy transition process. Therefore, a policy framework is needed to isolate the impacts of geopolitical risks and maximize the positive impacts of energy transition drivers.

Summary: This study examines the relationship between three Blockchain-based platforms (AIB, TIX, and BCDN) and global ESG indexes (ESG and SESG). The results show that BCDN has a higher coherence with ESG and SESG investments compared to AIB and TIX, but this coherence decreases with lower quantiles and shorter-term perspectives. Additionally, all Blockchain-enabled innovations significantly contribute to ESG-screened businesses under normal and bullish market conditions, except for the AIB-SESG pairs. Only BCDN and AIB provide network-transmitting functions in a bull market and a normal market respectively, indicating the market state-dependency of Blockchain-based innovation spillovers. Therefore, expecting significant contributions from BCDN or AIB in creating ESG markets and achieving sustainable objectives necessitates a focus on market conditions.

Summary: Energy saving, emission reduction, and low carbon development are crucial for sustainable development globally and for China's dual carbon target. The digital transformation of enterprises plays a significant role in reducing carbon emissions by improving technological innovation, internal control, and environmental information disclosure. Based on a text analysis of annual reports from Shanghai and Shenzhen listed companies during 2012-2020, the study measures the level of enterprise digital transformation and empirically investigates its impact on carbon emission intensity. The findings show that enterprise digital transformation effectively reduces carbon emissions, and this effect remains robust even after conducting various tests. The study also analyzes the heterogeneity and concludes that the impact of digital transformation is stronger in regions with strong intellectual property protection and capital-intensive enterprises. However, it does not differ based on enterprise types, environmental regulation intensity, and information infrastructure construction. This paper discusses the path choices for enterprises to reduce carbon emissions, offering insights for businesses to seize opportunities in the new wave of technological and green economic transition.
