This study aims to examine the relationship between economic development and environmental degradation based on the Environmental Kuznets Curve (EKC) hypothesis. The level of CO2 emissions is used as the indicator of environmental damage to determine whether or not greater economic growth can lower environmental degradation under the EKC hypothesis. The investigation was performed on eight major international economic communities covering 44 countries across the world. The relationship between economic growth and environmental condition was estimated using the kink regression model, which identifies the turning point of the change in the relationship. The findings indicate that the EKC hypothesis is valid in only three out of the eight international economic communities, namely the European Union (EU), Organization for Economic Co-operation and Development (OECD), and Group of Seven (G7). In addition, interesting results were obtained from the inclusion of four other control variables into the estimation model for groups of countries to explain the impact on environmental quality. Financial development (FIN), the industrial sector (IND), and urbanization (URB) were found to lead to increasing CO2 emissions, while renewable energies (RNE) appeared to reduce the environmental degradation. In addition, when we further investigated the existence of the EKC hypothesis in an individual country, the results showed that the EKC hypothesis is valid in only 9 out of the 44 individual countries.

The relationship between economic growth and environmental quality has been under much dispute. Over the years, several studies have identified inverted-U shaped relationships between per capita income and some measure of environmental degradation. This has led to the emergence of a burgeoning literature on what has come to be known about as the Environmental Kuznets Curve (EKC). According to the EKC hypothesis, environmental damage increases in the early stages of economic growth, but diminishes once nations reach higher levels of income. This literature is important as it acknowledges the possibility of trade and growth being good for the environment. Against this backdrop, we have attempted to give an overview of some of the studies published on EKC and subsequently critically appraised the same. The EKC has been criticised for its simplified assumptions and the literature appears to be largely econometrically weak. It has been shown to apply to select environmental indicators for certain countries; hence its validity as a universal phenomenon remains questionable. Owing to global implications of environmental degradation, more efforts are required to examine the validity of EKC as a global phenomenon by relating a composite index of environmental degradation to a better measure of economic development across nations.

The economy that continues to grow has the impact of environmental damage. This study aims to prove empirically the Environmental Kuznets Curve (EKC) hypothesis by analyzing the relationship of economic growth with environmental damage as measured by GDP per capita, and CO2 emissions. The data used are secondary data in the form of data on GDP per capita, CO2 emissions, population growth, inflation, and control of corruption in 10 countries in the ASEAN region in 2002-2016. Data analysis using the Fixed Effect model. The results show that there is a relationship between economic growth and environmental damage that forms an inverted U curve. Economic growth will initially have a positive effect on environmental damage so that at a point of economic growth negatively affects environmental damage. By adding control variables: population growth, inflation and corruption, inflation and corruption positively impact environmental damage, while population negatively affect environmental damage.

Sustainable development with three main pillars, namely environmental, economic, and social, is the concept of country’s development to achieve inclusive economic growth, good environmental quality, and improvement of people's welfare. However, the dominance of economic factors cause various environmental problem. This phenomenon occurs in most of developing countries, including in Indonesia. The relationship between economic activity and environmental quality has been widely discussed and empirically tested by scholars. This descriptive research analysed the hypothesis called Environmental Kuznets Curve (EKC) from a perspective of sustainable development in Indonesia. EKC hypothesis illustrates the relationship between economic growth and environmental degradation forming an inverted U-curve, indicating that at the beginning of development, environmental quality will decrease along with increasing economic growth, and then reached a certain point the environmental quality will gradually improve. In this paper will be discussed how the relationship between environmental quality and economic growth in Indonesia was investigated. The preliminary results show that most of the empirical studies use the conventional approach, in which the CO2 emission used as the proxy of environmental degradation. The existence of inverted U-curve is also inconclusive. Therefore, the extension research on the relationship between economic growth and environmental quality in Indonesia using the EKC hypothesis is required.

The relationship between economic growth and environmental quality has been much under dispute. According to the EKC (Environmental Kuznets Curve) hypothesis, environmental damage increases in the early stages of economic growth, but diminishes once nations reach higher levels of income. While the notion EKC is well established, there is controversy about its shape, incidence and determinants. In this paper, we model EKC with the variables of GDP and CO2 emissions (aggregate and per capita) using alternative model specifications to bridge the gap between conventional and modern EKC literature. We also place the theoretical construct of EKC into a policy-oriented framework by incorporating the impact of four global policy periods namely, liberalisation, globalisation, world recovery and global financial crisis. We substantiate a cubic form of EKC in the Indian context for the time period 1991 to 2014. With aggregate CO2 emissions as the dependent variable, the linear, quadratic and cubic terms are all significant with the expected signs, which confirm an N-shaped EKC for India. Even with per capita emissions as the dependent variable, existence of an N-shaped EKC is established. In this case however, evidence on the cubic term is rather weak which points towards the difference in socio-psychological factors that influence the revival of upturn in the case of India. The policy period analysis does not show any distinct results, which could be due to contradictory effects on different variables and volatility in these variables.

The rapid economic growth observed in Central European countries in the last thirty years has been the result of profound political changes and economic liberalization. This growth is partly connected with reducing carbon dioxide (CO2) emissions. However, the problem of CO2 emissions seems to remain unresolved. The aim of this paper is to test whether the Environmental Kuznets Curve (EKC) hypothesis holds true for Central European countries in an annual sample data that covers 1995–2016 in most countries. We examine cointegration by applying the Autoregressive Distributed Lag bound testing. This is the first study examining the relationship between CO2 emissions and economic growth in individual Central European countries from a long-run perspective, which allows the results to be compared. We confirmed the cointegration, but our estimates confirmed the EKC hypothesis only in Poland. It should also be noted that in all nine countries, energy consumption leads to increased CO2 emissions. The long-run elasticity ranges between 1.5 in Bulgaria and 2.0 in Croatia. We observed exceptionally low long-run elasticity in Estonia (0.49). Our findings suggest that to solve the environmental degradation problem in Central Europe, it is necessary to individualize the policies implemented in the European Union.

Penelitian ini bertujuan mengidentifikasi dampak pembangunan ekonomi dan proses industrialisasi terhadap Degradasi lingkungan di Indonesia baik dalam jangka panjang maupun jangka pendek. Untuk melihat pengaruh pembangunan ekonomi dan industrialisasi terhadap penurunan kualitas lingkungan di Indonesia, penelitian ini menggunakan model Enviromental Kuznet Curve (EKC) dan dengan model Error Correction Mechanism (ECM). Hasil penelitian menjelaskan bahwa dalam jangka panjang peningkatan pendapatan masyarakat dan industrilasasi berpengaruh positif  secara linier terhadap peningkatan emisi C02 dan pada tingkat pendapatan tertentu terjadi proses perbaikan lingkungan yang ditandai dengan penurunan emisi CO2. Namun dalam jangka pendek hanya industrialisasi yeng membrikan pengaruh pada peningkatan emisi CO2. Diharapkan adanya konsesus bersama antara pemerintah dan pelaku usaha (industri) dalam mengurangi dampak pencemaran serta adanya peningkatan kesadaran masyakat dalam membantu mengurangi kerusakan lingkungan hidup.   Abstract This study aims to identify the impact of economic development and industrialization to  the environmental degradation in Indonesia, both in the long term and short term. To see the effect of economic development and industrialization to the environmental degradation in Indonesia, this research was  used Environmental Kuznets Curve (EKC) model and the model of  Error Correction Mechanism (ECM). The results of the study explain that in the long term, improvement of people's income and industrialization have positive effect linearly with the increase in C02 emissions and at a certain income level there is a process improvement environment characterized by a decrease in CO2 emissions. But in the short term only industrialization which influence on the increase of CO2 emissions Expected that the consensus between the government and businesses (industri) in reducing the impact of pollution and the increased awareness of society in helping to reduce environmental damage.

Global warming has emerged as a serious threat to humans and sustainable development. China is under increasing pressure to curb its carbon emissions as the world’s largest emitter of carbon dioxide. By combining the Tapio decoupling model and the environmental Kuznets curve (EKC) framework, this paper explores the relationship between China’s carbon emissions and economic growth. Based on panel data of 29 provinces from 2007 to 2016, this paper quantitatively estimates the nexus of carbon emissions and economic development for the whole nation and the decoupling status of individual provinces. There is empirical evidence for the conventional EKC hypothesis, showing that the relationship between carbon emissions and per capita gross domestic product (GDP) is an inverted U shape and that the inflection point will not be attained soon. Moreover, following the estimation results of the Tapio decoupling model, there were significant differences between individual provinces in decoupling status. As a result, differentiated and targeted environmental regulations and policies regarding energy consumption and carbon emissions should be reasonably formulated for different provinces and regions based on the corresponding level of economic development and decoupling status.

The paper develops a two-state-variable environmental growth model to derive the optimal growth path for the relationship between pollution and economic growth, which is used to verify the existence of the Environmental Kuznets Curve (EKC) hypothesis. It is found that the theoretical outcomes imply the existence of the EKC relationship between environmental degradation and economic growth, which is dependent on the combining effects of the pollution intensity, abatement technology of pollution emission, production technology, and the return rate of capital stock.
