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: The study found a U-shaped EKC in Greenland, rather than the hypothesized inverted U-shape relationship. Greenland experienced an improvement in environmental quality during early development stages, but as industrial expansion took place, a positive and significant relationship between CO2 emissions and GDP per capita emerged, potentially harmful to the Arctic natural environment.

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 study fills an important empirical gap by examining the Environmental Kuznets Curve hypothesis and the impact of socioeconomic variables on ecological sustainability in Nigeria. The results support the existence of the curve, with energy consumption and total import exacerbating environmental deterioration, while total export improves environmental quality. Financial development contributes to a decrease in environmental destruction in the long run but escalates it in the short run. Urbanization causes an increase in environmental damage in the long run but a decrease in biodiversity loss in the short run.

Summary: The study did not confirm the presence of an N-shaped EKC in the emerging 7 countries but rather found an inverted U-shaped EKC. Results showed a positive and significant relationship between renewable energy and non-renewable energy with CO2 emissions, but short-term results indicated no significant relationship between economic expansion and CO2 emissions. Causality tests revealed bi-directional causality between GDP and GDP-squared.

Summary: The study reveals an inverted U-shaped Environment Kuznets Curve for APEC countries, with turning points in the impact of financial development and economic growth on the environment. There is a positive relationship between energy intensity and ecological footprint, indicating a negative impact on environmental sustainability.

Summary: This study examines the relationship between economic structure and economic complexity with environmental pollution in OECD countries, confirming the Environmental Kuznets Curve hypothesis. It finds that most OECD countries have a positive connection between economic complexity and CO2 emissions, with the service sector being the most pollutant. Policymakers should prioritize environmental impacts in service sector planning and encourage knowledge-intensive restructuring.

Summary: The study found supportive evidence for the inverted U-shaped relationship in the long-run, indicating that an increase in real GDP per capita and electricity consumption tends to mitigate long-run carbon dioxide emissions in developing countries. Country-specific findings suggested the presence of the EKC theory for Brazil, China, India, Malaysia, the Russian Federation, Thailand, and Turkey, indicating their path towards environmental sustainability. However, Mexico, Philippines, Indonesia, and South Africa failed to lend credence to the EKC theory, suggesting the need for strategies to reduce carbon dioxide emissions in these countries.

Summary: The environmental Kuznets Curve describes the deterioration and improvement of environmental quality with economic growth. However, this relationship may not follow the traditional inverted U-shaped distribution in different regions due to modern economy and policy factors. This paper conducts a quantitative linear regression analysis on economic growth and environmental pollution in a specific region, and provides high accuracy in analyzing the correlation between economy and environment compared to the traditional Kuznets curve. Suggestions and specific measures are also proposed based on the actual situation of the region.

Summary: This study introduces the use of the Armey curve hypothesis (ACH) to test the environmental Kuznets curve hypothesis (EKCH). The two hypotheses have similar inverted U-shaped curves, so they are combined into a single composite model to calculate the optimal level of government expenditures that will affect CO2 emissions for USMCA countries. The results show that only Mexico verifies the EKCH through the AC model. Additionally, the study calculates the optimal government spending level for Mexico, which will increase both per capita real GDP (RGDPPC) and CO2 emissions by 26.4% of RGDPPC.

Summary: The study used the ARDL model to test the validity of the EKC hypothesis under the moderating role of industrialization on CO2 emissions. The results showed a cointegration relationship between CO2 emissions, economic growth, economic growth squared, energy consumption, industrialization, and financial development. The findings supported the EKC hypothesis for economic growth and CO2 emissions, but not for industrialization. The study recommended transitioning to knowledge-based industrialization to reduce CO2 emissions and improve environmental quality.

Summary: Energy is important for economic growth and human survival, but it can also harm the environment. The study examines the energy environmental Kuznets curve (EEKC) for 144 countries from 1990 to 2017, finding that it holds true for higher middle-income countries but not for lower-income quantiles. The relationship between economic growth and energy consumption is positive and non-linear. The study suggests that developed countries should support developing countries in achieving economic growth while adopting energy-efficient technologies.

Summary: This study examines the greenhouse gas emissions in several EU New Member States from 1990 to 2019, using panel data and time series approaches. It identifies similarities and differences in the impact of various indicators on emissions and the agricultural sector. The research highlights the negative correlation between human development index/GDP and total GHG emissions, as well as the influence of economic growth on pollution in agriculture.

Summary: The study examines the validity of the Environment Kuznets curve with two different environment proxies, finding that it holds for ecological footprint but not for carbon emissions. Environmentally friendly indicators include energy intensity and financial development, while biomass energy consumption has a negative impact on environmental degradation. Causality findings reveal bidirectional links between economic development and emission, biomass energy consumption, and financial development, emphasizing the need to focus on policy options to improve energy efficiency for a cleaner environment.

Summary: This study investigates the relationship between nitrous oxide emissions and economic growth in Canada. The findings confirm the environmental Kuznets curve hypothesis and indicate that agricultural land use has a positive and significant effect on total N2O emissions. Additionally, Canadian exports are negatively associated with both total N2O emissions and agricultural induced N2O emissions.
