This paper aims to investigate whether there are any empirical relationships among corporate disclosure of environmental, social and governance (ESG) and firms ‘operational , financial (ROE & ROE) and market performance, and if these relationships are positives or negatives or even neutral. For the purpose yearly ESG Ratings data ranging from period 2016 – 2020 has been used to find the impact on NSE 100 listed firms in India. Empirical results suggest that there is statistically significant relation between ESG Ratings and Total Asset Turnover, which indicated the operational performance of firms. A firm’s TAT seems to be positively impacted by ESG ratings at 5% level. There is a positive relation of 21% among the two variables. All the variables do not seem to be impacted by ESG ratings and hence all other hypothesis have been accepted.
