Russia-Ukraine war impacts on climate initiatives and sustainable development objectives in top European gas importers.

Russia holds the position of being the third largest global producer of oil and plays a significant role in the supply of oil and gas to Europe. The ongoing war conflict has the potential to impede the bilateral and multilateral relations between Russia and Europe. The ramifications of this event will have notable reverberations for environmental endeavors in Europe. The aforementioned premise forms the basis of our investigation, wherein we scrutinize the correlation among oil price, coal price, gas price, economic growth, and coal consumption, while taking into account the ramifications of the Russian-Ukrainian conflict. We adopted fully "modified ordinary least square (FMOLS), dynamic ordinary least square (DOLS), and canonical cointegration regression (CCR)" econometric techniques to gauge the nexus between factors of interest in the top 4 European Russian gas importer economies (Poland, Netherland, Hungry, and Germany). The empirical outcomes reveal substantial negative impact of economic growth and coal price elasticity on the coal consumption. On the contrary, oil and gas price elasticities depict significant positive influence on the coal consumption. Hence, this study concludes that a rise in oil and gas prices leads to an increase in coal consumption, which in turn negatively impacts environmental quality. Furthermore, the occurrence of war has the potential to impede the utilization of coal resources in Netherlands and Hungary. On the other hand, the impact of war is noteworthy and constructive in Poland and Germany. Thus, war results ecological imbalance in Poland and Germany in particular. Governments, decision-makers, stakeholders, and environmentalists must develop a long-term plan that calls for a paradigm shift away from gas, oil, and coal usage and toward more environmentally benign renewable energy sources.

Testing the impact of renewable energy and oil price on carbon emission intensity in China's transportation sector.

As the largest carbon emitter in the world, with its transportation sector contributing the largest shares of its emission, the need for a low-carbon transition economy has become a policy agenda for China because in order to reach carbon neutrality by 2050, lowering the intensity of carbon emissions in the transportation sector will be crucial. In this regard, we used the "bootstrap autoregressive distributed lag model" to explore the impact of clean energy and oil prices on the intensity of carbon emissions in China's transportation sector. The study found that an increase in oil prices decreases the intensity of carbon emissions in the short and long run. Similarly, an increase in the level of renewable energy and economic complexity declines the intensity of carbon emissions in the transportation sector. On the contrary, the research demonstrates that non-renewable energy contributes positively to carbon emission intensity. Therefore, the authorities must promote green technology to neutralize the transportation system's detrimental effects on China's environmental quality. The implications for successfully promoting carbon emission intensity mitigation in the transportation sector are examined in the conclusion.

Do financial development and renewable energy shocks matter for environmental quality: evidence from top 10 emitting emissions countries.

Creating a reliable energy supply, ecological quality, and economic development has become a global effort. Finance is at the center stage ecological transition to low-carbon emission. Against this backdrop, the present work analyses the impact of the financial sector on CO2 emissions using data from the top 10 emitting emissions economies from 1990 to 2018. Using the novel method of moments quantile regression, the findings illustrate that renewable energy usage enhances ecological quality while economic growth lowers it. The results also affirm that financial development is positively linked with carbon emission in the top 10 emitting emissions economies. These results can be explained by the fact that financial development facilities offer low borrowing rates with less restrictions for environmental sustainability projects. The empirical findings of this study highlight the necessity for policies that boost the proportion of clean energy consumption in the top 10 polluting nations' overall energy mix to reduce carbon emissions. It follows that the financial sectors in these nations must invest in cutting-edge energy-efficient technology and clean, green, and environmentally friendly initiatives. This trend will increase productivity, improve energy efficiency, and reduce pollution.

Do banking sector development, economic growth, and clean energy consumption scale up green finance investment for a sustainable environment in South Asia: evidence for newly developed RALS co-integration.

Concern about climate change is spreading around the globe. The urge to comprehend the environmental effects and take action is sharply rising. Regarding this, the banking industry has a great chance to offer a solution in terms of green financial solutions and can meet the needs of carbon-conscious organizations to combat and defend our planet. Therefore, in light of this, according to the greatest understanding of the authors, this is the first study to investigate the role of banking sector development, economic growth, and clean energy consumption in scaling up green finance investment in South Asian nations, taking carbon emissions, foreign direct investment, remittances, inflation, and trade openness as control variables. This study uses a novel residual augmented least squares-Engle and Granger (RALS-EG) co-integration to test the long-term link and the quantile autoregressive distributed lag (QARDL) econometric approach to extract the association across the quantiles (q0.05-q0.95) for the period 2000-2020. The outcomes of QARDL show that banking sector development, economic growth, clean energy, carbon emissions, foreign direct investment, remittances, and trade openness play a positive role in attracting green finance in the long term. However, only inflation has a negative influence on scaling up finance in South Asian nations. Therefore, the concerned authorities (government, central banks, environmentalists, and policymakers) are urged to implement green finance policies and strategies as suggested and recommended by the results of this study.

Climate change, insurance market, renewable energy, and biodiversity: double-materiality concept from BRICS countries.

The threat of biodiversity loss and mass extinction of species with an aftermath will shape all lives now and those to come. In this context, recent empirical studies illustrate various drivers of biodiversity for better environmental quality; however, the impact of the insurance market has not been thoroughly examined. Likewise, the possible non-linearities between biodiversity and its determinants are ignored in the current empirical literature for BRICS economies. Therefore, this work is the first to explore the effect of the insurance market, climate change, and renewable energy on biodiversity in BRICS economies using an advanced method of the non-linear autoregressive distributed lag (NARDL) method. The findings illustrated that a decline in the insurance market alleviates biodiversity loss and stimulates environmental quality. In contrast, an increasing insurance market augments biodiversity loss and negatively affects ecological quality. Furthermore, the findings uncovered that carbon emissions are detrimental to environmental quality. Lastly, the results report that reducing the level of renewable energy worsens biodiversity loss while boosting renewable energy utilization declines biodiversity loss. The policymakers and regulatory authorities in the BRICS should adopt the risk-based approach proposed by the network of greening the financial system (NGFS) to tackle the dilemma of double materiality between financial institutions and biodiversity.

Nexus between energy consumption and carbon dioxide emission: evidence from 10 highest fossil fuel and 10 highest renewable energy-using economies.

The world, addressing to achieve rapid and drastic economic growth by relying on fossil fuel energy consumption, could increase already increasing level of carbon dioxide (CO2). Therefore, there is a growing consensus that environmental sustainability by using renewable energy is the only option to avoid environmental calamity. Therefore, according to the authors' best knowledge, this is the first work to look into the short and long-run nexus between economic growth, trade openness, renewable and fossil fuel energy consumption, along with gross capital formation, population growth, and life expectancy as additional variables in top 10 highest renewable energy-using (TRU) economies and top 10 highest fossil fuel-using (TFU) economies from 1991 to 2020, by employing advanced panel data econometric approach. After demonstrating cross-sectional dependency in panel data, the Westerlund cointegration test verifies the long-term link between the variables. A cross-sectional autoregressive distributed lag (CS-ARDL) econometric technique is used to show short- and long-run coefficient values. CS-ARDL estimates confirm that the economic growth, fossil fuel energy, trade openness, and gross capital formation increase carbon dioxide (CO2) emissions levels in the short run for TRU and FEU economies, except for gross capital formation for FEU economies. However, economic growth adds to CO2 emissions for only TRU economies, while fossil fuel energy consumption enhances CO2 emissions for both groups of economies in the long run. On the contrary, renewable energy reduces CO2 emissions in the short and long run, while human capital in only the short run. The inferences of this study present new intuitions and urge governments and policymakers to develop a reliable mechanism for investing capital to diversify the energy portfolio through the energy transition process to attain sustainable economic growth and promote awareness campaigns to draw the attention of human capital to environmentally friendly, clean, and green energy sources. Overall, the results recommended energy efficiency usage and ecological friendly innovative technologies to enhance and protect environmental quality.

An all carbon dye sensitized solar cell: A sustainable and low-cost design for metal free wearable solar cell devices.

Lightweight carbon electrodes are the new candidates for photovoltaic devices due to their temperature resistivity, ease of fabrication, and skin comfortability. Herein, a sustainable and facile strategy has been proposed for metal free all carbon dye sensitized solar cell (C-DSSC), assembled by stacking carbon front electrode (CFE) and carbon counter electrode (CCE). The CFE demonstrated adequate light transmittance (70-50%) while maintaining efficient photon absorption and charge separation mechanism due to dye coated TiO2 nanorods (P25-R). The graphene dip coated carbon counter electrode (Gr@CCE) possesses remarkable electro catalytic activity towards I3-/I- redox couple with low charge transfer resistance (RCT = 0.79 Ω). The sustainable design of C-DSSC attained ~6 ± 0.5% efficiency with high photocurrent density of 18.835 mA. cm-2. The superior performance of C-DSSC is accredited to its improved charge mobility, low internal resistance, and better interfacial electrode contact. The thickness of C-DSSC is ≤3 mm eliminates the need for rigid glass in DSSC.
