This papertries to examine how emission of CO2 responds to the growth of per capita GDP, changing share of manufacturing and international trade in India for the period 1960 to 2020. The ARDL and Cointegration methods are employed to examine the short and long run quadratic relationships of the time series data. The results suggest that a long run relation exists among CO2 emission, economic growth, manufacturing output and export as a percentage of GDP. The existence of an EKC in India is however associated with short run insignificant relation of CO2 emissions with manufacturing output and export in proportion to GDP. The long-run existence of EKC hypothesis in India, proves that economic growth is the means to environmental improvement in the long run. However, the positive relation of manufacturing share in GDP with CO2 emissions alerts for taking care of growth of manufacturing but with serious environmental management and control of emission standard and overall pollution.
