ABSTRACT This study uses a quantile autoregressive distributed lag model to quantitatively evaluate the effects of economic policy uncertainty (EPU) and geopolitical risk (GPR) on volatility in carbon futures (carbon trading price [CTP]), considering both time asymmetries. The findings show that long‐term GPR CTP are more significant than short‐term effects, contrary EPU. Both EPU have predominantly positive CTP, while negatively affects factors mixed influences short term. location asymmetry reveals impacts most pronounced at higher quantiles, whereas exhibit subtle variations across different quantiles. intensify during structural shifts owing heightened events. Moreover, is proven as dominant contributor influencing fluctuation long terms. provide targeted recommendations for policymakers stabilize contribute towards achieving sustainable development.

As environmental pollution intensifies, China has begun to implement green credit policies reduce allocation highly polluting enterprises. This research examines the influence of on cash flow heavily enterprises, based implementation “Green Credit Guidelines”. The policy creates a quasi-natural experimental setting by giving businesses access an exogenous occurrence. Consequently, this paper uses data from 494 A-share listed companies in over fifteen-year period 2007 2021 and employs Difference-in-Differences (DID) model assess net effect policy, positing that scheme will prevent making money. empirical findings show significantly reduces emit lot pollutants, especially when it comes operational flow. Heterogeneity analysis reveals high-emission regions non-state-owned enterprises is affected even more significantly. Previous often overlooked as metric; however, critical indicator enterprise’s status. From angle, study adds our knowledge how schemes affect businesses. Additionally, contributes ongoing discussion regarding relationship between financial constraints China’s government ought keep encouraging creation regulations, enhance supervision state-owned pay attention low-emission establishing dynamic regulatory indicators promote ecological civilization construction transformation upgrading lagging industries.

This paper discusses the uncertainty spillover among climate policy, economic energy market and geopolitics, using time-varying parameter vector autoregression (TVP-VAR) connectedness approach. The major results show that total index (TCI) is dominated by long-term in static analysis. main transmitters are policy China (CPUC) (EPU) while receivers USA (CPUS) energy-related (ERU) when considering time frequency. Next, dynamic analysis, TCI exhibits a downward trend, net directional indicates CPUC still pure transmitter, CPUS plays completely opposite role. Finally, pairwise analysis shows exerts spillovers on EPU, ERU geopolitical risk. Conversely, more likely to accept shock of other uncertainties. contribution different uncertainties incorporated into unified research framework, explain detailed influencing channels. More importantly, this recognizes roles entire with frequency, argue reshaping global economy, situation. Some policies, including prudent firm international cooperation, depoliticization climate-related decisions, provided for promoting development, stabilizing tensions.

This paper uses the GJRSK model to estimate high-order moments of energy (oil, natural gas, and coal), carbon market, tourism stocks. Then, it utilizes a novel TVP-VAR time-frequency connectedness approach examine higher-order spillovers among them. The results show strong three markets. market is emitter volatility, skewness kurtosis spillovers; stock receiver; transmitter. From time-domain perspective, markets are time-varying, especially during extreme periods, where market’s spillover effects on stocks significantly enhanced, indicating that bear greater risk at leptokurtosis fat-tail moment. frequency-domain long-term asymmetric oil, more pronounced than short-term. Moreover, COVID-19 pandemic exacerbated higher-moment market. Meanwhile, Russia-Ukraine conflict led transmission within These findings have significant implications for cross-industry investors green finance management.

This research examines the correlation between COVID-19 pandemic and desire to engage in compensatory consuming behaviors, specifically emphasizing emotional eating as a psychological coping strategy, particularly with respect snacks sweets. Conducting sentiment analysis by using Natural Language Processing (NLP) method on posts from Sina Weibo, leading Chinese social media platform, identifies three distinct phases of consumer behavior during pandemic: anxiety, escapism, periods. These stages are marked varying degrees tendencies, illustrating trajectory initial shock seeking comfort through food means regaining sense normalcy control. The reveals notable increase expressing for consumption sweets 2020 compared 2019, indicating significant shift towards amid pandemic. reflects broader impacts crisis, offering insights into role digital platforms capturing public global crises. findings have implications policymakers, health professionals, industry, suggesting need strategies address behavioral effects natural disasters.

This paper investigates the influence of Renewable Portfolio Standards (RPSs) on reliability grids while considering key indicators, including System Average Interruption Duration Index (SAIDI), Frequency (SAIFI), and Customer (CAIDI), both without with inclusion Major Event Days (MEDs). The study adopted instrumental variable quantile regression (IVQR) method for estimation purposes. first-stage 2SLS results confirm robustness validity instruments used, Democrats’ Participation Rate, Real Household Income, Energy Capacity, which show strong relevance satisfy conditions homogeneity. Our findings demonstrated that adoption RPS policies has significantly decreased interruption power in all considered quantiles. impact is more potent states facing severe challenges. proved important role RPSs improving stability context having relatively poor reliability. In summary, obtained demonstrate significant insights related to renewable energy resilience infrastructure. Finally, suggest government authorities should promote as a tool enhancing performance different states.

This study explores the long-run relationship among environmental footprint (EnF), renewable energy consumption, use, industrial growth, and urbanization in Saudi Arabia from 1990 to 2023, employing Autoregressive Distributed Lag (ARDL) model, alongside Fully Modified Ordinary Least Squares (FMOLS), Dynamic (DOLS), Canonical Cointegrating Regression (CCR) for robustness checks. Results indicate a significant long-term variables, with adoption emerging as crucial factor reducing carbon emissions. The ARDL bounds test confirms existence of cointegration, revealing dynamic interplay energy, economic sustainability. findings show that consumption significantly reduces (CO2 emissions), supporting Arabia’s Vision 2030 goals diversification sustainable development. However, expansion, while critical still contributes increased emissions, underscoring need further investment clean technologies. also highlights role urbanization, which, essential development, poses challenges Short-term dynamics, represented by Error Correction Model, fast adjustment speed toward equilibrium, deviations corrected approximately 52% each period. offers valuable insights policymakers aiming balance growth protection, emphasizing strategic investments efficiency. research understanding energy–economy–environment interactions oil-rich economies, providing foundation future studies explore impact advanced technologies policy interventions on development

The paper illustrates the dynamic causal connection between green finance (GF) and carbon emissions (CO 2 ) from global perspective. study indicates that correlation GF CO is not uniform in different periods. has a dual effect on , negative may be caused by technological innovation, positive explained lower prices of traditional energy. Meanwhile, exerts beneficial as result environmental pressures such climate change, whereas it visible impact owing to factors imperfect financial markets. By analyzing three paths limiting highly polluting enterprises, innovation policy signals, purpose this develop theoretical framework order demonstrate significance variables. In addition, explains reasons for correlations over time view. Countries around globe can take measures according causes, which will great benefit reducing emissions. article, further makes relevant proposals improving system market, vital importance governments, others.
