A Reference Model of Sustainability Disclosure based on four Sustainability Stock Indexes

The study proposes to develop a reference model of sustainability disclosure based on the models and requirements of four sustainability indexes - Dow Jones Sustainability Index, Corporate Sustainability Index ISE, Frankfurt STOXX and Financial Times FTSE ESG. The approach employed to develop the model is a qualitative analysis of the complementarity among the Stock indexes above mentioned alongside a literature review on sustainability disclosure frameworks. There is no consensus around what should be measured and how. Yet, there is no study in the literature that has ever discussed the models of the sustainability stock indexes and the respective data required in each one of them or compared these models and their requirements. The present study attempts to fulfill this gap by examining the initiatives and requirements of four prominent sustainability indexes. This study contributes to the sustainability responsible investment literature. The inclusion of a firm in a sustainability index can be perceived as a positive signal by investors and this can be explained by signaling theory. This analysis can help investors and/or socially responsible fund managers to screen the stocks against this reference model and determine those firms that are more adherent to it.
