In an age of fear, insecurity, and multiple and overlapping crises, the fortunes of ESG— the idea that companies should include environmental, social, and governance standards of good performance—are now steadily growing. This is all the truer in the West, where corporate financial misconduct and, more worryingly, corporate political activities impacting democratic processes, have become a matter of evident concern. Business scholars and policymakers are, however, still uncertain about which corporate activities merit an ESG label, with pressure groups pushing for their own ESG definitions and standards according to their agendas and beliefs. Against this background, this paper contributes to this Special Issues’ guiding question of how religions can act as agents of civic mobilisation by critically examining their role in addressing sustainability topics due to religious concerns from a legal perspective. This current paper hopes to create a preliminary intellectual bridge between two apparently unrelated fields of research (law and religion; corporate governance) that could help scholars in both areas to develop expertise and sophistication in applying their respective specialities to an otherwise unfamiliar area.
