“…Considering the focus of this study, that is, to evaluate the potential effects of FDI on environmental quality (pollution haven–pollution halo) in Brazil, we anchored insights from extant studies (Ahmad et al, 2020; Al‐mulali & Foon Tang, 2013; Islam et al, 2021; Lateef et al, 2021; Opuala et al, 2023) for empirical expositions. Based on the above‐stated contending proposition, CO 2 represents the dependent variable, while FDI represents the key explanatory variable.…”

In this study, we re‐examined the pollution haven and halo hypotheses in Brazil for approximately five decades (1970–2019) while controlling for the effects of income, renewable energy and natural resource depletion. For clearer insights, the study employed both the conventional autoregressive distributed lag (ARDL) and the enhanced kernel regularized least squares (KRLS) techniques. Notably, the KRLS is a flexible machine learning nonlinear analytical technique that explains the interactions of the regressand and the regressors both at the average and across a range of quantiles. After ascertaining cointegration through the bounds tests and the Bayer–Hanck procedures, the following empirical outcomes emerged: The ARDL result suggests the acceptance of the pollution haven hypothesis in Brazil in both the short and long runs. However, the KRLS technique reveals that foreign direct investment (FDI) could enhance environmental quality (pollution halo) within the 25th quantile of the distributions of CO2 emissions. However, at the 50th and 70th quantiles, the pollution haven hypothesis is rectified. This suggests the adoption of varying policy options to ensure continuous inflows of FDI without compromising environmental quality. Additionally, among the control variables, a U‐shaped environmental Kuznets curve (EKC) structure is revealed from the influence of gross domestic product (GDP); renewable energy ensures a clean environment at all times, while resource rent ensures a clean environment only at the 25th and 50th quantiles of the distributions. Policies that could lead to clean environments in Brazil have been provided.

“…where the series that have been defined earlier retain their notations, while the subscripts i and t imply cross-sectional dimension and time dimension, b 0, b 1 -b 7 and ε it imply coefficients of the constant term, the explanatory variables and the stochastic term, respectively. It is imperative to highlight that all the panel series have been transformed into natural logarithmic values to enable interpretations on the basis of elasticities (see 3,4,56 ).…”

“…The model also avails reliable estimates amidst cross-sectional dependences. 3,30 Likewise, the procedure is equally an efficient technique in the case of weak exogeneity that may appear due to the lagged response variable in the specified equation. Furthermore, the technique prevents the endogeneity problem by adding the lagged cross-sectional averages in the equation.…”

“…The analysed results emanating from the PMG-ARDL and CS-ARDL highlight some interesting features that are critical for devising robust environmental sustainability pathways in E7 countries. Accordingly, each of the three selected EQ indicators (ECF, CO 2 D and CCO 2 ) are represented as separate models (1)(2)(3) in that other. On account of the PMG-ARDL, it is established that ENS provides significant long-term impediments to carbon emissions in the E7 countries, mostly on ECF.…”

“…It is indeed very worrisome and an issue of critical concern how the global environmental ecosystem is being compromised uncontrollably chiefly on the instance of human activities. On account of several prior studies, [1][2][3][4][5][6][7] the quest for economic advancements and overall development seems to have blindfolded humankind, leading to compromised ecosystems both in developed and developing countries. To respond to the mounting challenges of ecological imbalances, global economies have entered into several international conventions/treaties that were conscientiously constituted and crafted to ensure comprehensive abatement of continuous environmental decay.…”

Revisiting Hofstede's dimensions of national culture and environmental sustainability

This study investigates the impact of Hofstede's dimensions of national culture on environmental sustainability across 57 countries. Hofstede's national culture construct reflects and gauges the extent of the inclination of a particular national person toward either economic development or environmental preservation. Climate change and pollution have continuously devastated the environment in recent decades. The United Nations Sustainable Development Goals aim to achieve a more sustainable future and prevent further environmental destruction. This study aims to explore whether national culture significantly influences national environmental sustainability. We use national environmental performance as the proxy for national environmental sustainability and adopt the ordinary least squares regression model to explore the possible relationship with two datasets of international indices; one is proposed by Hofstede, and the other is proposed by Germanwatch. Our results show that the power distance index has a strong negative impact on the climate change performance index (CCPI), greenhouse gas (GHG) emissions, renewable energy, and energy use. Further, the masculinity index is negatively related to CCPI and GHG emissions. The individual index is also negatively related to renewable energy. Furthermore, indulgence is positively associated with climate policy. These findings support the notion that nations should consider their cultural characteristics to improve environmental sustainability. Thus, conducting a national environmental policy that aligns with national culture is suggested to achieve environmental sustainability.

Time‐Quantile and Frequency Response of Green Growth to Energy Vulnerability, Energy Uncertainty, and Geopolitical Risks

The study explains the time‐quantile‐frequency adjustments of green growth to energy vulnerability, energy uncertainties, and geopolitical risks (GPR) in the United States (US). Novel insights with notable policy implications emerged following the empirical analysis of monthly data spanning 2000 m1–2022 m12. The study implemented the Wavelet Quantile Correlation (WQC), Wavelet Quantile Granger Causality, and the Rolling Windows Wavelet Quantile Granger Causality to understand the dynamics among the variables. Evidence from WQC divulged time‐specific positive and negative interactions between green growth and its determinants. Specifically, energy vulnerability dampened green growth more profoundly in the immediate and medium terms. However, in the long term, green growth prospers amidst energy vulnerability. This outcome reflects some policy effectiveness that reduced the negative effects of energy vulnerability for green growth. The effects of energy uncertainties are similar to that of energy vulnerability, with more profound damaging effects in the lower medium horizon of the distributions. GPR dampened green growth in the short run and enhanced it in the medium term, but it reduced green growth more profoundly in the long run. The pleasant effects of energy efficiency and digitalization are observed mostly in the long run, with notable green growth‐reducing effects mainly in the short run.
