The Environmental Kuznets Curve hypothesis is a theoretical proposition explicating the link between a locality's income level and environmental degradation. Previous studies estimated the current relationship with an unchanging parameter. However, due to changes in global conomic and political conditions, natural disasters, technological shocks, and implemented policies, the link between income and environmental degradation is about to change. The study investigates the income-pollution nexus for G7 countries-Canada, France, Germany, Italy, Japan, the UK, and the USA-from 1970 to 2014 using a novel methodology: bootstrap panel rolling window causality. In this context, this approach is advantageous for determining the link between income and pollution level in sub-sample periods, rather than assuming an unchanging parameter, and captures the hidden causal linkages between income and environmental pollution. The results confirm the validity of the EKC hypothesis in Japan and the USA, whereas in the other countries, the relationship between EF and GDP exhibits no evidence for an inverted U-shaped pattern.

This research chooses Pakistan as an ideal case to explore the connection between economic expansion and carbon emissions, by incorporating a novel approach of using coupled stochastic equations to estimate this dynamic interaction.The GDP (Gross domestic product) in Pakistan has been ascending over the time of 1960-2023, with short episodes of stagnation (mid 80s) and decline (1973, 2009). Since 2010, the growth rate has been rising annually, reaching 4.

This study examines the Waste Kuznets Curve (WKC) hypothesis by integrating it with the Tapio decoupling model to explore the relationship between economic development and e-waste imports in 45 emerging economies from 2002 to 2022. The empirical results show that (1) the relationship between economic growth and e-waste imports exhibits an inverted U-shaped curve, with decoupling achieved when GDP per capita exceeds the WKC turning point of $10,755.23; (2) Emerging economies are categorized into six quadrants based on their e-waste decoupling status: high-income non-decoupling, low-income non-decoupling, low-income relative decoupling, high-income relative decoupling, low-income absolute decoupling, and high-income absolute decoupling; (3) Most emerging economies remain in low-income non-decoupling state, with only a few countries like China and Poland achieving high-income absolute decoupling.

Concerns about global climate change, resource scarcity, and environmental degradation continue to escalate. Within this context, the circular economy has received widespread attention as a model of sustainable development. Simultaneously, China's regional economic integration (REI) strategy has been regarded as an important tool for promoting economic growth and optimizing resource allocation.

The study analyzes the impact of environmental regulations on carbon emissions in countries with different levels of emissions, utilizing two measures of carbon emissions based on: production (PBA) and consumption (CBA) accounting. Environmental regulations are measured by means of three components of the Environmental Policy Stringency (EPS) index: market-based and non-market-based instruments, and technology support. The Moments-Quantile Regression method is employed to assess the effectiveness of these policies across countries with varying levels of emissions-high, medium, and low within the Environmental Kuznets Curve.
