The purpose of this paper is to research the relation among environmental quality and renewable energy in the RECAI country group. The study used per capita CO2 emission, energy intensity, and Aggregate National Savings as a measure of environmental quality. Other variables used in the study are renewable energy consumption, fossil fuel consumption, GDP per capita, and foreign direct investments. In the study, three different models to see different environmental quality indicators by panel quantile method for 19202090–. According to the results obtained, unlike other models, renewable energy consumption in model 1 positively affects energy intensity in all quantiles. In other words, renewable energy consumption negatively affects environmental quality. In model 1 and model 3, the coefficients of fossil fuel consumption were positive and negative, respectively. Unlike model 2, the coefficient estimates of fossil fuel consumption in model 3 were predominantly negative. Fossil fuel consumption shows a positive effect on environmental quality, which is similar to model 1. Economic growth negatively affects environmental quality in all models. There is a one-way causal relationship from renewable energy consumption to energy intensity and energy intensity to growth. [ABSTRACT FROM AUTHOR]

This study aims to explore the relationship among economic growth, CO2 emissions, fossil fuels consumption, renewable energy consumption, foreign direct investments, and trade by taking into account countries with oil reserves (export groups) and countries without oil reserves (import group). The factors affecting CO2 emissions in countries with and without oil production have been investigated by using Panel VAR (PVAR) and Granger causality methods for the period of 1990–2015. In both country groups, growth positively affects CO2 emissions. While there is a negative relationship between CO2 emission and foreign direct investments in the oil importing country group, there is a positive relationship between CO2 and trade in the oil-exporting group. PVAR analysis results illustrate that the growth hypothesis is valid in both groups of countries. In addition, when both country group examined, the countries sacrifice their national income to reduce carbon emissions, which makes it difficult to reduce emissions in the world. According to the variance decomposition results, while the CO2 variable defines itself as 98% for oil importing countries, the second important variable that pollutes the air is GDP. In addition, the variables FDI, REN and FOSSIL affect air pollution by 4% over a 10-year period. [ABSTRACT FROM AUTHOR]
