This paper investigates the influence of environmental (E), social (S) and governance (G) disclosure, and the composite ESG disclosed by firms on their sales performance. Using the 2SLS IV regression method, the study analyses 826 global firms across seven years spanning the 2008 financial crisis to understand how firms use ESG to promote sales in normal and disruptive periods.The effects of ESG and S alone on sales are significantly positive, while no significant effect of E and/or G is found. ESG has a robust significant effect on sales in the time of market turbulence, but the effect is not robust in normal time. The interaction of E*S/E*G/S*G is also analysed. Even the effect of E alone on sales tends to be negative in our results, the interactive effect of S and E has a positive impact on sales. The study suggests ESG as a whole and S, in particular, is an effective marketing instrument. This paper is among the first to investigate the influence of ESG in whole or in part on sales using a global-level dataset, taking into account a contextual factor, i.e., market turbulence time.
