The paper examines the impact of macroeconomic variables on CO2 emissions, very few research studies are available to estimate the asymmetric impact and causality. Because of the significance of asymmetries, this paper examines the asymmetric impact of economic growth, crude oil use, and FDI inflows on CO2 emissions in the India wherein COP (Crude oil price) is comprised as the extra variable. The implicate aggressive growth of selected variables over the period 1990-2020 is also assessed. This study uses the methodology ARDL and NARDL model to determine the macroeconomics variable's effects on CO2 emission over the period 1990-2020. Additionally, also applied the EKC (Environmental Kuznets Curve) hypothesis with an application of ARDL and NARDL model. With help of the ARDL and NARDL model, the study shows the results that a rise in economic growth would reduce CO2 (carbon dioxide) emissions while a decrease in economic growth would raise CO2 emissions which indicates an inverted U-shaped Curved relationship between economic growth and CO2 emissions. The positive and negative shockwaves in COP (crude oil prices) have a satisfactory and substantial impact on CO2 emissions as well. Besides, the crude oil consumption with positive shockwave confirmations has a positive and substantial impact on CO2 emission. In addition, the results of FDI inflows support the pollution heaven hypothesis. In light of these outcomes, this paper also recommended policy implications and future research, the policy implications are where the descending flow of FDI allows limited space to India in FDI selection; however, the existence of emission merging and implementation of carbon pricing may facilitate India in achieving its environmental targets.
本文考察了宏观经济变量对二氧化碳排放的影响,很少有研究能够估计不对称影响和因果关系。由于不对称性的重要性,本文考察了经济增长、原油使用和外国直接投资流入对印度二氧化碳排放的不对称影响,其中包含了石油价格作为额外变量。还评估了所选变量在 1990 年至 2020 年期间急剧增长的影响。本研究使用 ARDL 和 NARDL 模型来确定宏观经济变量对 1990 年至 2020 年期间二氧化碳排放的影响。此外,还应用了 ARDL 和 NARDL 模型检验了环境库兹涅茨曲线(EKC)假说。通过使用 ARDL 和 NARDL 模型,研究表明,经济增长的上升将减少二氧化碳(CO2)排放,而经济增长的下降将增加 CO2 排放,这表明经济增长与 CO2 排放之间存在倒 U 形曲线关系。石油价格的正向和负向冲击对 CO2 排放也有令人满意和实质性的影响。此外,原油消费的正向冲击证实了对 CO2 排放的正向和实质性影响。此外,外国直接投资流入的结果支持污染天堂假说。根据这些结果,本文还提出了政策建议和未来研究,政策建议是外国直接投资的下降流动使印度在外国直接投资选择方面空间有限;然而,排放合并的存在和碳定价的实施可能有助于印度实现其环境目标。
