Abstract

Despite considerable research attention given to the environmental Kuznets curve (EKC), little has been known about its true form and particularly the mechanisms that explain it. Using panel quantile regression, this paper designs a multivariate framework for exploring the EKC in the European Union in the period 2004–2017 and unveils the distributional heterogeneity effect hidden therein. It reveals that complexity in the relationship under consideration turned out to be higher than evidenced or assumed in the literature so far since its shape changed the form across the conditional distribution of greenhouse gas (GHG) emissions. Moreover, the paper shows that the use of efficient energy and renewable energy has the power to outweigh the scale effect. Simultaneously, it questions the efficiency of environmental and energy taxes and opens the issue of the rebound effect and the association between energy poverty and GHG emissions.

Abstract
Despite considerable research attention given to the environmental Kuznets curve (EKC),
little has been known about its true form and particularly the mechanisms that explain it.
Using panel quantile regression, this paper designs a multivariate framework for exploring
the EKC in the European Union in the period 2004–2017 and unveils the distributional
heterogeneity effect hidden therein. It reveals that complexity in the relationship under con-
sideration turned out to be higher than evidenced or assumed in the literature so far since
its shape changed the form across the conditional distribution of greenhouse gas (GHG)
emissions. Moreover, the paper shows that the use of efficient energy and renewable energy
has the power to outweigh the scale effect. Simultaneously, it questions the efficiency of
environmental and energy taxes and opens the issue of the rebound effect and the associa-
tion between energy poverty and GHG emissions.

1 Introduction
The European Union (EU) has confirmed its commitment to tackling climate change as its
priority and an opportunity for transitioning to a low-carbon economy through its strategic
documents (European Commission, 2011, 2014). Although the EU works hard to achieve
its emission reduction targets, greenhouse gas (GHG) emissions were at a higher level in
2018 than they were in 2014 (Eurostat, 2020). At the same time, GHG emissions signifi-
cantly vary across EU countries, ranging from the average 6 tons per capita in Latvia to
24.93 tons per capita in Luxembourg in the period 2004–2018 (Eurostat, 2020). This raises
concerns and calls for new policy actions.
Understanding the association between environmental degradation and the economy is
important for creating adequate policy mitigation initiatives and consequently fully imple-
menting strategic documents. This is because adequate policy actions and measures can

... It is necessary to understand the association between environmental degradation and the economy in a country, so based on the information on its energy transition path, more adequate policy mitigation initiatives can be created [33]. Therefore, to gain better insight into counties' location of their transition trajectories, the theory of the environmental Kuznets curve (EKC) is used. ...
... However, GDP per capita has a heterogeneous effect on GHG emissions, which indicates that general economic development alone cannot reduce GHG emissions; it is necessary but not a sufficient condition. The environmental and energy policies, strategies and measures are essential factors in reducing GHG emissions; however, its effectiveness and efficiency vary across GHG distribution [33]. In order to achieve greater reductions in greenhouse gas emissions, pro-environmental and country-specific national policies are required [33], and the adaptation of energy efficiency measures in all sectors of the economy have to be accelerated [16]. ...

The Paris Climate Agreement and the 2030 Agenda for Sustainable Development Goals declared by the United Nations set high expectations for the countries of the world to reduce their greenhouse gas (GHG) emissions and to be sustainable. In order to judge the effectiveness of strategies, the evolution of carbon dioxide, methane, and nitrous oxide emissions in countries around the world has been explored based on statistical analysis of time-series data between 1990 and 2018. The empirical distributions of the variables were determined by the Kaplan–Meier method, and improvement-related utility functions have been defined based on the European Green Deal target for 2030 that aims to decrease at least 55% of GHG emissions compared to the 1990 levels. This study aims to analyze the energy transition trends at the country and sectoral levels and underline them with literature-based evidence. The transition trajectories of the countries are studied based on the percentile-based time-series analysis of the emission data. We also study the evolution of the sector-wise distributions of the emissions to assess how the development strategies of the countries contributed to climate change mitigation. Furthermore, the countries’ location on their transition trajectories is determined based on their individual Kuznets curve. Runs and Leybourne–McCabe statistical tests are also evaluated to study how systematic the changes are. Based on the proposed analysis, the main drivers of climate mitigation and evaluation and their effectiveness were identified and characterized, forming the basis for planning sectoral tasks in the coming years. The case study goes through the analysis of two counties, Sweden and Qatar. Sweden reduced their emission per capita almost by 40% since 1990, while Qatar increased their emission by 20%. Moreover, the defined improvement-related variables can highlight the highest increase and decrease in different aspects. The highest increase was reached by Equatorial Guinea, and the most significant decrease was made by Luxembourg. The integration of sustainable development goals, carbon capture, carbon credits and carbon offsets into the databases establishes a better understanding of the sectoral challenges of energy transition and strategy planning, which can be adapted to the proposed method.
... Forming an image capable of highlighting the progress made by any country in terms of climate change, green transformation and ensuring sustainable development, as well as the implementation status of the 2030 Agenda sustainable development goals (SDG) is currently possible as a result of studies with global and European coverage made by organisations such as the United Nation (The United Nations Economic Commission for Europe [UNECE], 2012;UNECE, 2021), OECD, World Bank (Laderchi et al., 2013), Global Green Growth Institute (GGGI) (Acosta et al., 2022;Acosta et al., 2021;Acosta et al., 2020;Acosta et al., 2019) and Eu-7 ropean Union [EU] (European Commission, 2022;European Commission, 2020), but also due to reports and research conducted by scientific community (Brodny & Tutak, 2023;Cheba et al., 2023;Lu et al., 2023;Wolde-Rufael & Mulat-weldemeskel, 2023;Mealy & Teytelboym, 2022;Ionescu et. al., 2022;Cheba et al., 2022;Boubellouta & Kusch-Brandt, 2023;Borozan, 2022;Batrancea et al., 2021;Rybalkin et al., 2021;Cătuți et al., 2020;Kasztelan, 2018;Pociovălișteanu et al., 2015) specifying that most of them can be found alongside other countries in rankings and comparisons. ...

Research background: The transition towards a green economy, seen as a visible alternative to climate change and the need to ensure this opportunity to future generations, is a major challenge for all of the nations of the world, regardless of their status as developed, developing or emergent. In order to highlight the current state or progress towards a green economy, the reports and research of certain institutions, as well as of the academic medium, have focused on identifying the most relevant influencing factors and choosing the quantification methods capable to generate complete and useful interpretations. Purpose of the article: The purpose of the paper is to construct an instrument that enables to measure the progress of countries in terms of the transition to green economy, where Romania is considered as a case study. In this respect, a composite index (green economy index — GEI) is being proposed, achieved by aggregating some indicators for measuring sustainable development. The method underlying the calculation of the value of the GEI aggregate index allows not only to determine the current state of greening of the economy, but also provides information on the contribution made by each of the three dimensions of sustainable development (economic, social and environmental), as well as by each indicator individually, to this progress. Methods: Constructing the aggregated index was based on an additive aggregation of three partial indicators: the economic indicator, comprised of 8 individual indicators, the social indicator, comprised of 8 individual indicators, and the social indicator, comprised of 10 individual indicators. The collected data covers the interval of 2010–2021. Findings & value added: Calculating the Green Economy Index — GEI value for each of the 12 years under analysis has permitted not only the identification of progress regarding the green transition, and the underlying of each indicator’s contribution to this evolution, but has also confirmed the results obtained by similar studies carried out by the GGGI or European Union. We consider, as a result of the selection of certain indicators considered relevant in the economic, social and environmental field, that the newly-formed aggregate index represents an effective tool that can be used to measure progress in terms of achieving the 2030 Agenda for Sustainable Development goals, by easily adapting to the particularities of other states or regions.

Factors such as investments in environmentally clean technologies, globalization, and institutional quality significantly increase environmental quality. The study aims to provide light on how environmental technologies, institutional quality, globalization, and economic growth affect a sustainable environment. In addition, this study evaluates the European Union’s carbon zero target by 2050 and the results of achieving carbon neutrality by 2030, which was put on the agenda at the UN Climate Change Conference of the Parties (COP-26). For this purpose, ten countries (Germany, Austria, Denmark, Finland, France, Netherlands, Spain, Italy, Sweden, and Switzerland) that invest in the highest environmental technology in the European Union were selected in the study. The data range of the study is from 1990 to 2019. Also, the validity of the load capacity curve (LCC) hypothesis was investigated in these countries. The CCEMG and DCCE estimators were used to estimate long-run coefficients. When the panel was assessed as a whole, the LCC hypothesis was determined to be valid by both estimators. According to country-based results, it has been determined that the LCC hypothesis is valid only for Spain. The study also includes the following observations. (i) Environmental technologies increase LCF for Austria, improving environmental quality. (ii) Globalization reduces LCF for Austria. (iii) Institutional quality variable decreases LCF for Austria and increases LCF for Germany and France. These findings suggest that to attain a sustainable environment in the future, policymakers should raise research and development budgets for environmental technology, enhance the standards of institutions, and take globalization into account.

This study extends the energy tourism growth discussion by adopting the concept of market segments when investigating tourism proxies. We adopt econometric procedures to identify potential structural breaks and cross-sectional dependence together with appropriate panel data model specifications. Causality tests are also processed to search for the direction of potential linkages. The rationale behind such an approach is to integrate the energy growth nexus discussion with the tourism growth nexus into one specification and investigate holistically potential impacts and causalities under a new, unobserved in relative literature set of variables. Interestingly, we offer to the relevant literature in the following ways: first, the concept of market segments regarding business and leisure tourism spending as a proxy for tourism expansion is used. Second, we also encompass internal consumption, by international and domestic visitors, instead of international receipts when searching for causalities. Third, we consider capital investment spending within the travel and tourism sector. This issue is less visible, if not unnoticed, in relevant studies since the vast majority adopt the concept of foreign investment spending. Our empirical findings confirm the conservation hypothesis, while the feedback hypothesis is also present in our specifications. Practical implications demand effective management within the tourism system to foster pro-environmental behavior and achieve efficient energy use within the economic system.

This paper introduces a quantile regression estimator for panel data (QRPD) with nonadditive fixed effects, maintaining the nonseparable disturbance term commonly associated with quantile estimation. QRPD estimates the impact of exogenous or endogenous treatment variables on the outcome distribution using “within” variation in the instruments for identification purposes. Most quantile panel data estimators include additive fixed effects which separates the disturbance term and assumes the parameters vary based only on the time-varying components of the disturbance term. QRPD produces consistent estimates for small T. I estimate the effect of the 2008 tax rebates on the short-term household consumption distribution.

The present study examines the heterogeneity of renewable energy consumption, Carbon dioxide emission and financial development in the global panel of 192 countries. Panel quantile regression has been used for tickling distributional and unobserved individual heterogeneity. The findings indicate that our variables in the model on each others are heterogeneous across quantiles. More specifically, the effect of renewable energy consumption on carbon emission is negative while financial development has increasing influence on carbon emission. Carbon emission decreases the use of renewable energy while financial development positively affects renewable energy consumption. The increasing effect of carbon emission and renewable energy consumption on financial development has also been found. Finally, the current study findings give important recommendations to policy makers.

The aim of the paper is to apply the Environmental Kuznets Curve (EKC) model in order to explore the link between economic complexity index (ECI) and carbon emissions, in 25 selected European Union (EU) countries from 1995–2017. The study examines a cointegrating polynomial regression (CPR) for a panel data framework as well as for simple time series of individual countries. In the model is also included the variable ‘energy intensity’ as main determinant of carbon emissions. Depending on economic complexity, the CO2 emissions pattern was found to exhibit an inverted U-shaped curve: in the initial phase, pollution increases when countries augment the complexity of the products they export using and after a turning point the rise of economic complexity suppress the pollutant emissions. The panel cointegration test indicates a long-run relationship between economic complexity, energy intensity and carbon emissions. It was also found that a rise of 10% of energy intensity would lead to a 3.9% increase in CO2 emissions. The quadratic model incorporating ECI is validated for the whole panel as well as for six countries (Belgium, France, Italy, Finland, Sweden and the United Kingdom). The graphical representation of the EKC in these countries is discussed. Policy implications are also included.

Decoupling energy consumption and carbon emissions from economic growth is at the core of the climate change debate: successful decoupling is evidence that efficiency measures can be economically sustainable. In this article, the authors analyze the underlying nature of this decoupling in the European Union from 1990 to 2014. The objective is to quantify the role of structural changes and the effectiveness of energy efficiency measures in lowering energy consumption. We decompose final energy consumption per sector, including households and transportation into three key drivers: economic growth, economic structure and energy intensity. Our results show that a significant part of the reduction in energy consumption can be attributed to structural changes, such as deindustrialization, while an equally significant part can be attributed to energy efficiency. This further corroborates the idea that much of the observed decoupling is virtual; largely due to outsourcing of energy intensive activities. Energy is then imported in the form of embodied energy in goods and services. The dynamics of these effects suggest that a shift in our understanding of decoupling is necessary. The implementation of effective energy efficiency policies, accounting for embodied energy, remain of high priority.

The relationship between CO 2 emissions, the main gas responsible for global warming, and economic growth is among the most studied themes of environmental economics. Reducing overall emissions while keeping a high pace of economic development is at the heart of the sustainable development concept. When emissions grow less rapidly than GDP environmental economists speak of relative decoupling; if emissions even decrease relative to the pace of economic growth, then decoupling is absolute. Assessing these options requires an empirical analysis of the emissions-GDP relationship. The study of this nexus has special importance for developed countries, given their historical responsibility towards global warming. At the same time, in the last decades, the same countries have been at the forefront of the fight against climate change in terms of emissions-reduction efforts. By applying cutting-edge econometric techniques, this paper aims to investigate the decoupling options, if any, for a group of European economies which can be considered as pioneers in pursuing the sustainable development goals. This question gains further importance considering that some recent studies have found positive GDP elasticities of emissions for certain developed countries, which may be seen as a cause of concern for the sustainable development path of such countries. Unlike the bulk of the literature, in this paper, we allow the income elasticity of emissions-a critical indicator for the study of decoupling-to vary over time. The reason is that the elasticity might change through the time due to the factors affecting the main drivers of the CO 2 emissions. We use a time-varying coefficients cointegration approach to investigate the CO 2 emissions-GDP relationship for 12 Western European countries over a long time period ranging from 1861 to 2015. Our main finding is that the income elasticity of CO 2 emissions is positive in all investigated countries. In addition, we find evidence in favor of relative decoupling in 8 out of the 12 European countries. This is in line with the fact that the selected European countries have shown more determination in adopting carbon reduction policies before and after the Kyoto protocol period and toward the Paris agreement compared to other leading economies such as China, United States, and Russia. For the remaining 4 cases, the income elasticity of CO 2 emissions is in excess of unity. This can be considered as a call for policymakers to take quick and relevant measures to mitigate emissions level without harming the economic development.

ASEAN (Association of Southeast Asian Nations) has contributed numerous carbon emissions during the phase of industrialization. This studymainly compares the different effects of export and import on CO2 emissions across 7 ASEAN countries over 1990–2017. In addition,we investigate how technological innovation affects carbon emissions. Stationary tests are conducted through cross section dependence, unit root of panel data, and Westerlund cointegration. The results of panel quantile regression showthat export and import both have adverse effects on CO2 emissions. EKC is valid in these countries. Moreover, population size and energy intensity increase carbon emissions. In particular, technology innovation significantly reduces carbon emissions by augmenting energy efficiency. It is important to improve eco-innovation, and expand knowledge-intensive industries in ASEAN countries.

The adoption of energy-efficient and clean energy resources is crucial in reducing greenhouse gas emissions. The study analyzes the heterogeneous effects of energy efficiency (EE), renewable energy (RE), and other variables on carbon emissions within the context of the environment Kuznets curve (EKC) hypothesis in 66 developing countries from 1990 to 2014. This study incorporates the role of EE in the construction of the EKC hypothesis, which has been neglected in the previous literature. By using panel ordinary least squares and fixed-effect panel quantile regression (PQR), we find that the impact of the decisive factors of CO2 emissions are heterogeneous across different quantiles. Specifically, EE reduces CO2 emissions across all quantiles, but the mitigation effect is strongest at the 90th quantile. RE reduces CO2 emissions and shows a substantial effect at the 10th quantile. Nuclear energy consumption reduces CO2 emissions but significantly influences carbon emissions only at the 50th quantile. GDP (Y) increases CO2 emissions, but the escalating effect of Y increases at the upper quantiles. The squared of GDP (Y2) reduces CO2 emissions and shows the strongest mitigation effect at the upper quantiles. The quantile coefficients of Y and Y2 are significantly positive and negative, respectively, thereby verifying the existence of the EKC hypothesis in developing countries. In sum, EE and RE contribute to reducing carbon emissions in developing countries. These results also verify EE as an essential factor in the formation of the EKC hypothesis in developing countries and offer some important recommendations for designing and implementing appropriate economic and energy policies to achieve environment sustainability in these countries.

The paper investigates the effect of energy taxes in the European Union (EU) across different levels of residential final energy consumption (RFEC) in the period 2005–2016. The analysis is based on quantile panel regression models that directly and indirectly consider energy taxes. More precisely, the developed models provide a multivariate framework for evaluating their effects and, at the same time, for validating the existence of the energy environmental Kuznets curve (EKC) across the selected quantiles. The results unveil significant heterogeneity in the RFEC responses across quantiles. Specifically, in less energy-consuming EU countries, an increase in energy taxes and energy prices influences stronger RFEC, and the rebound effect of real income and tertiary education is greater than in their more energy-consuming peers. Moreover, in the former, the energy EKC hypothesis holds, while in the latter, its existence is not clear, as well as the rebound effect caused by highly educated people. Consequently, EU energy policy aiming at achieving energy and environmental targets has to consider the heterogeneity in RFEC since the outcomes might be different for different energy-consuming groups of countries.

How feasible is it to eradicate poverty by 2030, whilst tackling climate change? What would be the impact of poverty eradication on emission levels and needed mitigation rates? The question is crucial as it addresses the two most critical challenges of our time. Despite the necessity to address both issues simultaneously, a significant gap exists in the empirical literature as poverty and environmental outcomes, including both the level of emissions and energy use per capita, have been researched separately. While it has been shown that no country has achieved high human development with sustainable environmental consumption, more research is needed to link emissions and energy use with poverty directly. This paper aims to fill this gap by summarizing the existing literature and by estimating the poverty-energy-emissions pathway across countries and time using country level data from 149 countries, representing the majority of global emissions, energy use and poverty. The findings show that current poverty-energy-emissions pathways can be approximated by a generalized logistic function, with extreme poverty eradication associated with relatively low levels of per capita emissions and energy use. Second, the analysis demonstrates that a weak decoupling process, between emission levels and poverty, has taken place in the last two decades. It also shows, however, that this decoupling process is less evident when energy use (rather than emissions) is considered. Finally, through a comparison of different scenarios, the study indicates that the eradication of global poverty by 2030 following the estimated pathways would mean an increase in emissions significantly higher compared to the case in which poverty is eradicated through targeted policies. The paper concludes by underlining the need for a stronger decoupling. Nonetheless given the difficulty of achieving further reductions in energy intensity, and the barriers for a complete de-carbonization of the energy system, alternative development approaches are also proposed.
