Abstract: This study extends prior research and takes a robust account of the effects of economic growth on environmental quality in India, using several single-equation and system estimators and considering multiple structural breaks over ‘long’ as well as ‘short’ time periods. The long-run model is estimated on annual data for the period 1951–52 to 2015–2016. The results provide robust support for the positive and significant effects of gross domestic product and financial development and for the negative effects of trade openness and domestic investment on carbon dioxide emissions. The presence of structural breaks challenges the validity of smooth and continuous relationship between income and emissions postulated in previous research. Policy intervention, in terms of the imposition of Pigouvian tax, allocation of carbon quotas and promotion of carbon ‘cap-and-tax’ and/or ‘cap-and-trade’ systems, is needed to correct market failure, to cover the external cost of pollution and to curtail the emission of carbon. It is worth subsidizing alternative sources of energy, adopting carbon-efficient technologies and switching to carbon-neutral substitutes.
