Investigation of environmental kuznets curve for pollutant emission levels in dhanbad, Jharkhand

This study aims to explore the possible relationship between economic growth and pollutant emissions in Dhanbad, Jharkhand. Specifically, the focus will be on three pollutants: nitrogen dioxide (NO_2 ), particulate matter (PM10) and sulphur dioxide (SO_2 ). The results of Sequential Mann-Kendall test statistics indicate that per capita GDDP has been increasing since 2015, which is statistically insignificant. However, there is a significant SQ-MK change point for pollutant emission levels in this analysis. The study also shows that economic growth correlates with higher levels of pollutant emissions. According to the study, there is a significant negative relationship between per capita GDDP and nitrogen dioxide concentration, with a correlation coefficient of -0.72. The study also found a negative correlation between GDDP and particulate matter (PM10) concentration, with a correlation coefficient of -0.3. Furthermore, the study suggests a strong negative correlation between GDDP and sulphur dioxide concentration in the context of Dhanbad, with a correlation coefficient of -0.8. According to the EKC analysis, nitrogen dioxide concentration, particulate matter (PM10) concentration, and sulphur dioxide concentration exhibit a statistically significant U-shaped Environmental Kuznets Curve.
