The continuous upsurge in worldwide economic development and human activities has intensified CO2 emissions that highlighted the significant role of eco-innovation and green investment in curbing CO2 emissions. The study aims to explore the impact of eco-innovation and green investment on CO2 emissions by using the China dataset for time period 1990–2019. The study adopts the ARDL approach. The study used two proxies to determine the impact of eco-innovation, namely environment-related technologies and patents. The empirical estimates of the ARDL approach confirm the negative impact of eco-innovation and green investment on CO2 emissions confirming that these determinants result in limiting CO2 emissions in China. Based on these findings, the study suggests strengthening environmentally friendly policies and the advancement of green investment to mitigate CO2 emissions. [ABSTRACT FROM AUTHOR]

This article aims to explore the co-movement of daily returns among S&P green bonds (GB/GBs), the top five sustainable cryptocurrencies, Bitcoin, the Dow Jones Sustainability World Index (DJSWI) and the Dow Jones Sustainability Emerging Market Index (DJSEMI) to determine whether GBs, Bitcoin and sustainable cryptocurrencies are truly sustainable; in addition, it investigates hedging and diversification opportunities. Using a partial wavelet coherence framework to capture the bivariate co-movement, our findings show strong (weak) positive co-movements among GB (sustainable cryptocurrencies) and DJSWI returns, where GBs (sustainable cryptocurrencies) have a heterogeneous leading role in the short-term and long-term horizons. Results indicate moderate positive (negative) co-movement among GBs and sustainable cryptocurrencies (Bitcoin) and DJSWI in the short run (long run). Overall, the results show GB (sustainable cryptocurrencies) acts as a diversifier for Bitcoin and sustainable cryptocurrencies in most cases (DJSWI). However, increasing Bitcoin returns adversely impacts the DJSWI in the long run. Findings are equally imperative for green investors, crypto traders and policymakers, where investors and traders can earn financial and social returns, and policy-makers can deploy suitable policies for the development of sustainable cryptocurrency mining processes. The role of Bitcoin is alarming for the United Nations Sustainable Development Goals and global greener economy. [ABSTRACT FROM AUTHOR]

This study aims to examine the influence of environmental performance (PM2.5) on COVID-19 intensity. For this purpose, we employ the newly introduced Hidden Panel Cointegration test and Nonlinear Panel Autoregressive Distributed Lag model. Results indicate the asymmetric linkages between PM2.5 and COVID-19 intensity, as the positive shock in PM2.5 raises the COVID-19 intensity by 21%, whereas the negative shock in PM2.5 decreases COVID-19 intensity by 12% in long-run. On the contrary, the positive shock in stringency measures decreases COVID-19 intensity by 42.8%, while the negative shock in stringency policy increases COVID-19 intensity by 66.7%. These findings imply that higher pollution increases the COVID-19 severity while higher stringency measures slow down people's movement and reduce COVID-19 intensity. However, a sudden negative shock in lockdown increases people's interaction, leading to a higher spread of the virus. These results suggest that governments should adopt stringent action plans to contain the transmissibility of COVID-19. [ABSTRACT FROM AUTHOR]

The research work presented in this paper is focused on the investigation of damping characteristics and structural optimization of the tapered composite hybrid smart rectangular sandwich plates. The composite rectangular hybrid sandwich plate contains the constraining and base layers made of multi-walled carbon nanotubes reinforced composite (CNTRC) face sheets and the core layer made of multi-walled carbon nanotubes reinforced magnetorheological elastomer. Higher-order shear deformation theory (HSDT) and finite element (FE) formulations are employed to derive the governing equations of the CNTRC rectangular hybrid smart sandwich plate. The performance of the derived HSDT model is validated by comparing the results in terms of natural frequencies evaluated using experimental tests on the composite hybrid smart sandwich structures under different support conditions. The influence of CNT reinforcement on the damping performance of the tapered rectangular hybrid smart sandwich plates are explored. Also, the optimal ply orientations of the tapered CNTRC rectangular sandwich plates with hybrid core is identified using the developed HSDT model coupled with Genetic Algorithm (GA) to enhance the natural frequencies and loss factors. Further, it can be observed that the reinforcement of CNTs in composites significantly influences the stiffness and damping characteristics of the tapered composite rectangular smart sandwich plates.

The present article investigates the dynamic characteristics of jute fiber-reinforced sandwich composite panels with periodic cores. The sandwich panel contains the jute fibers-reinforced polymer (JFRP) composites as face layers and the silicone rubber as the core layer. The tensile and flexural properties of JFRP composite material were examined using ASTM D3039 and ASTM D7264 standards. The finite element model was developed to obtain the dynamic properties of the composite sandwich panel with conventional and periodic cores. Furthermore, the influence of end condition, core to face layer thickness ratio, and face layer to core thickness ratio on the dynamic properties of the sandwich panels are presented. The numerical results indicate that the periodic core composite sandwich panel greatly influences the structural stiffness compared with a conventional composite sandwich panel.

Green investment is a trending marketing strategy that has been endorsed as a prominent financial actor due to the growing environmental issues and business sustainability. With the introduction of green and climate bonds in the last decade, the investment in eco-friendly projects has been deemed a paradigm shift. China has been a pioneer in introducing green and climate bonds, setting a precedent for green investment in the global market. Following the green strategy, therefore, the main aim of this study is to examine the importance of green investment and green marketing for enhancing business performance. Besides, this study has also examined the critical mediating role of CSR. Data were collected from 619 respondents from Chinese manufacturing companies via questionnaires. This study employed the structural equation modeling (SEM) technique to test hypotheses in Smart PLS software. This study revealed that green marketing strategy and green investment positively complement the CSR of companies and their business performance. Moreover, results also showed that CSR plays a significant mediating rolein enhancing business performance positively by stimulating the targeted relationships. With the ascendency of being environment friendly, this study will also be a powerful magnet for practitioners and policymakers. [ABSTRACT FROM AUTHOR]

Amid raising ecological concerns, the role of sustainable financial system and emerging technologies have gained significant attention. And a relatively less attention has been given to these factors in emerging economies. Therefore, this study intends to investigate the effects of financial development and technology innovation on climate change (CO2 emissions) in Emerging Seven countries over the period 1980–2020. In doing so, we have adopted a dynamic panel data model, that is, generalized method of moments, where climate change is given as an endogenous function of financial development and technology innovation by controlling the effects of economic growth, trade openness, population, industrialization, and urbanization. The overall results exhibit that the direct effect of financial development on climate change is adverse; however, the indirect effect through moderation of technology innovation is significantly positive. These outcomes imply that technology innovation is imperative to neutralize the negative consequences of financial development on climate change. These findings advocate financial reforms that effectively encourage and incentivize firms to embrace efficient and environmental friendly technologies in the financial sector. [ABSTRACT FROM AUTHOR]
