This paper seeks to provide a novel approach and insight into the synergies between corporate social responsibility (CSR), environmental disclosure (ED) and financial reporting quality (FRQ) which is emerging and changing rapidly. The study examined the nexus between corporate social responsibility (CSR), environmental disclosure (ED) and financial reporting quality (FRQ) among corporate entities listed on the Nigeria Stock Exchange (NSE). Data were collected from a sample of 169 listed firms in Nigeria. The research used a panel data set comprising of 624 firm year observations spanning the period 2015 to 2017. The empirical results of the study revealed that there exists a significant relationship between environmental disclosure(ED), firm size (FS), and financial reporting quality (FRQ). However, empirical evidence shows an insignificant relationship between social disclosure (SD), leverage and financial reporting quality (FRQ). We therefore recommend a proposal for the establishment of an inductive corporate social responsibility/environmental disclosure/financial reporting framework that future scientists/scholars can institute to explore the determinants of corporate social responsibility (CSR), environmental disclosure (ED) and financial reporting quality (FRQ) in developing countries.
