All over the world, deterioration of environmental quality has been considered as a hot issue. The growing number of industries is one of the major reasons for the enhanced level of pollution and fast degradation of environmental resources. This situation urges the corporates to involve themselves in socially responsible activities and to periodically assess the ecofriendly technologies. This paper proposes to investigate the Environmental Kuznets Curve Hypothesis, with reference to sample companies listed in BSE S&P – 500, over the period 1^st April 2005 to 31^st March 2014. In order to determine the existence of EKC relationship, the sign and magnitude of regression coefficients were analyzed. The results exhibited U shaped relationship for ROE, ROCE, and ROS. At the same time, EKC relationship, by way of inverted U shaped curve, was found for ROA. Based on the empirical findings of this study, some suggestions have been put forward to the corporates and policy makers, to control the level of energy intensity, by implementing eco-friendly technologies.
