Summary: This article investigates the role of fiscal policy in mitigating CO2 emissions. The study finds a positive association between fiscal policy and CO2 emissions based on the analysis of data from the Group of Twenty countries from 1995 to 2019. Therefore, the recommendation is to reconsider fiscal policy and redirect it towards supporting clean energy projects, providing incentives for projects combating environmental degradation, and relying on environmentally friendly energy.

Summary: This paper examines GHG emissions in Central and Eastern European countries from 1990 to 2019 and proposes economic policies to reduce pollution, finding an inverse N-shaped relationship between GDP and GHG emissions, and an N-shaped relationship between value added in agriculture and pollution. The study confirms a U-shaped renewable energy Kuznets Curve for overall economy and agriculture, suggesting that reducing pollution can promote sustainable development in these countries.

Summary: This study investigates the existence of the agriculture-induced environmental Kuznets curve hypothesis in 47 developing countries during 1976-2017. The findings suggest an inverted U-shaped relationship between income and CO2 emissions, while agricultural production has a negative impact on environmental quality. These empirical results provide important implications for policy makers to reassess the current production infrastructure of the agricultural sector for achieving sustainable development.

Summary: Within the EU, economic activity is rising in most developed countries, leading to increased carbon dioxide emissions. To maintain sustainable growth, the EU must quickly find solutions to pollution. The STIRPAT model considers population, wealth, renewable energy, nuclear energy, and R & D to determine their environmental impacts. The study found that population growth and fossil fuel use are major causes of environmental degradation, while renewables and higher incomes can reduce pollution in the long term. R & D investments also help lessen environmental damage, but nuclear energy has insignificant effects.

Summary: This study aims to examine the relationship between CO2 emissions, economic development, renewable energy, and agricultural production in Pakistan. The results indicate a long-term association and support the Environmental Kuznets Curve hypothesis. In the short term, crop production is negatively correlated with CO2 emissions, while renewable energy is negatively correlated with CO2 emissions.

Summary: This research reexamines the validity of the EKC hypothesis in the top three polluted nations in Africa, Algeria, Egypt, and South Africa, over the period 1970-2020. By incorporating the ARMEY curve into the Kuznets curve, the study aims to estimate the long-run drivers of environmental deterioration and determine the optimal government spending to reduce CO2 emissions. The results show that the composite model is only valid in Algeria and fails in South Africa and Egypt, with energy consumption and population identified as key drivers of environmental degradation in all three countries.

Summary: This study examines the associations between unemployment, GDP, population growth, renewable and non-renewable energy use, and ecological footprints in South Asian countries using annual data from 1991 to 2019. The findings show that GDP, non-renewable energy use, and population growth have positive effects on environmental degradation, while renewable energy use and unemployment reduce environmental deprivation. The study also confirms the presence of the environmental Phillips curve in South Asian countries. Policy instruments are proposed to reduce environmental pollution, including increasing the share of renewable energy and revising urban policies.

Summary: This study analyzes the asymmetric long-run relationship between economic growth, foreign direct investment, and carbon emissions in China, and provides strong evidence of the environmental Kuznets curve and the pollution haven hypothesis in the country. The use of advanced quantitative analysis methods validates the effectiveness of these relationships. The study recommends strengthening legal measures to further reduce carbon emissions.

Summary: This study reveals that oil returns influence renewable energy stock index returns in normal market conditions, but not in extreme market conditions. Additionally, renewable energy sector stock returns do not predict oil returns under any market conditions, however, there is a significant bidirectional causality between oil price volatility and renewable energy stock volatility at lower quantiles.

Summary: The paper examines the relationship between natural resource rents and economic growth, finding support for the natural resource bless hypothesis in the long run, but not in the short run. Economic growth has a positive impact on resource rents, and a feedback causal relationship exists between the two variables. Additionally, there is heterogeneity of results across countries in the short run.

Summary: The paper examines the causal effects of various factors on international food price volatility, including oil prices, fertiliser prices, global economic activity, and geopolitical risk. The analysis shows heterogeneous results in terms of the significance of causal linkages. Cereal prices are found to be the most sensitive to the considered variables, while geopolitical risk is the most critical factor affecting all food commodities. The findings suggest the importance of considering different market conditions and provide policy recommendations.

Summary: Climate change is a serious threat to humanity, but its spatial aspect has not been adequately addressed. This research examines the direct and indirect effects of climate change on economic growth using temperature variations. The findings suggest that climate change has no substantial effects on economic growth in general, but does have direct and indirect spillover effects in low-middle-income countries and in the hottest countries in the long run. The research emphasizes the need for international collaboration in climate change mitigation and adaptation strategies.

Summary: The paper empirically examines the effects of different categories of environmental taxes on CO2 emissions in 34 OECD countries from 1995 to 2019. The study finds a nonlinear association between environmental taxes and CO2 emissions, and dynamic panel threshold regression reveals that environmental taxes, energy tax, and pollution tax can effectively reduce CO2 emissions once a certain threshold level is reached.

Summary: This study examines the effects of natural resource exploitation on the ecological footprint in Saudi Arabia from 1981 to 2018. The results show that oil and natural gas rents have a positive symmetric association with the ecological footprint in the long run, while mineral resources have no significant impact. In the asymmetric analysis, it is found that only increases in total, oil, and natural gas rents deteriorate the ecological footprint in the long run, and decreases in natural resource rents have no effects. The shock analysis reveals that a 10% increase in total and oil rents leads to a 3% environmental degradation in the long run, while a similar increase in natural gas rents induces a 4% deterioration in environmental quality. These findings can contribute to the design of effective resource-use policies for environmental sustainability in Saudi Arabia.

Summary: This paper compares the predictive performance of the Support Vector Regression (SVR) and the eXtreme Gradient Boosting (XGBoost) models with the Autoregressive Integrated Moving Average ARIMAX (p,d,q) model for the crude oil volatility index before and during the COVID-19 pandemic. The results show that the SVR model outperforms the XGBoost and ARIMAX models in predicting the crude oil volatility index before COVID-19, while the XGBoost model provides more accurate predictions during the pandemic. The analysis of feature importance reveals that the SVR model performs better in terms of feature importance.

Summary: This study empirically examines short- and long-run determinants of entrepreneurial activity in a sample of 15 Middle East and North African economies between 2006 and 2018. Findings show that unemployment, trade openness, population density, and economic freedom are the main drivers of new business creation in the short-run, while the cost and number of procedures to start a new business negatively affect entrepreneurship. In the long-run, education, political stability, and the absence of violence/terrorism positively impact entrepreneurial activity.
